An architectural floor plan includes elements that determine movement of people within the architectural space and that play an important role in relating people and architecture. Especially since modern times, various shapes that deviate and escape from a floor plan by means of right-angled constitution have arisen and have been used as elements of architecture. Therefore, it is necessary to consider "a floor plan". We propose an index that classifies floor plans from a person's view, analyzing them by the modified box-count method comparing results, and proposing consideration.

This study proposes a technology that allows automatic extraction of vectorized indoor spatial information from raster images of floor plans. Automatic reconstruction of indoor spaces from floor plans is based on a deep learning algorithm, which trains on scanned floor plan images and extracts critical indoor elements such as room structures, junctions, walls, and openings. The newly developed technology proposed herein can handle complicated floor plans which could not be automatically extracted by previous studies because of its complexity and difficulty in being trained in deep learning. Such complicated reconstruction solely from a floor plan image can be digitized and vectorized either through manual drawing or with the help of newly developed deep learning-based automatic extraction. This study proposes an evaluation framework for assessing this newly developed technology against manual digitization. Using the analytical hierarchy process, the hierarchical aspects of technology value and their relative importance are systematically quantified. The analysis suggested that the automatic technology using a deep learning algorithm had predominant criteria followed by, substitutability, completeness, and supply and demand. In this study, the technology value of automatic floor plan analysis compared with that of traditional manual edits is compared systemically and assessed qualitatively, which had not been done in existing studies. Consequently, this study determines the effectiveness and usefulness of automatic floor plan analysis as a reasonable technology for acquiring indoor spatial information.

This study case comes from a large-scale comprehensive gymnasium that is under construction. It is a frame structure, and the total height is 23.5m, and the main beam in 2nd and 4th floor are post-tensioned bonded pre-stressed concrete structure with a longs span to 27m. As the thickness and the ration of steel bars of the bottom slab could not bear the load caused by construction and besides, before the terminal tension, the bracing to support the template could not be demolished to turnover; so, the plan that needs to tense from the upper floor to lower floor recurrently has not been adopted. Another construction process that proposes to tense the beams in one floor as soon as they are casted .However, Due to construction time limit and cost, this plan was not carried out. At last, we combining the two plans. In our plan, pre-stress tension and building construction were carried out simultaneously. According to accurate analysis of construction propose and flow, with careful check on main components, security, economics and building functions are uniformed together optimally.

Analysing traditional residential architecture in the Balkan region, we notice a widespread use of a split level horizontal house plan. The paper studies and presents examples found in Greece, Macedonia, Bulgaria, Serbia, Montenegro, Bosnia and Herzegovina and Croatia. Based on spatial, functional and structural analysis of the house plans, depending on the reasons for the horizontal floor level split and the types of its implementation, there are different groups of buildings. One group features a structural floor level split in order to match the line of the terrain; because of the implemented floor structure; or because of a bay window or a projection construction on the façade. In the other group of buildings the reasons are of a functional nature rooted in climate, social or religious sphere. Here the floor level difference is achieved by applying secondary construction elements and certain interior details. Having conducted the analysis, we can conclude that the implementation of various horizontal floor plan level in traditional, vernacular architecture is quite significant and inspirational for the modern design process in residential houses. It shows how dynamism and complexity can be achieved in a simple way, without any partitions, giving a picturesque effect of a basic interior space.

Floors have a key role in the seismic behaviour of structures, especially in multi-story buildings. The in-plane behaviour of a floor system influences the seismic response of the structure significantly and affects the distribution of lateral forces between seismic resisting systems and over the height of the structure. In buildings where the seismic resisting systems are in the same location in plan on each floor over the height of the building, inertial and displacement compatibility shear forces are the principal shear forces generated at the interface between the floor system and the seismic-resisting system. These two are called interface diaphragm forces. These interface forces must be transferred into the appropriate lateral load resisting system and the interface must be well designed and detailed. Determination of the magnitude of the interface loads on concrete diaphragms are not well understood and still a matter of debate. There is no consensus of a design procedure for determining the diaphragm actions and distribution into the seismic resisting systems. In this paper, interface forces generated in floor diaphragms by asymmetrical actions of the braced framing system on each side of the building in the direction of analysis have been investigated. A numerical study using Numerical Integration Time History Analysis (NITH), has been undertaken to evaluate the interface forces of concrete floor diaphragms in a 12-story braced steel building. The results of nonlinear time history analyses using ground motion records from three different earthquakes are presented.

Over the years, Mobile Mapping Systems (MMSs) have been widely applied to urban mapping, path management and monitoring and cyber city, etc. The key concept of mobile mapping is based on positioning technology and photogrammetry. In order to achieve the integration, multi-sensor integrated mapping technology has clearly established. In recent years, the robotic technology has been rapidly developed. The other mapping technology that is on the basis of low-cost sensor has generally used in robotic system, it is known as the Simultaneous Localization and Mapping (SLAM). The objective of this study is developed a prototype of indoor MMS for mobile mapping applications, especially to reduce the costs and enhance the efficiency of data collection and validation of direct georeferenced (DG) performance. The proposed indoor MMS is composed of a tactical grade Inertial Measurement Unit (IMU), the Kinect RGB-D sensor and light detection, ranging (LIDAR) and robot. In summary, this paper designs the payload for indoor MMS to generate the floor plan. In first session, it concentrates on comparing the different positioning algorithms in the indoor environment. Next, the indoor plans are generated by two sensors, Kinect RGB-D sensor LIDAR on robot. Moreover, the generated floor plan will compare with the known plan for both validation and verification.

The operation of the high-line speed cattle abattoir studied follows a plant-created hazard analysis and critical control point (HACCP) plan that is recognized by the Canadian Food Inspection Agency. Measurement of bioaerosols is not a part of this plan. In this study CFUs in air of selected abattoir processes were enumerated after impinging air onto tryptic soy agar plates with a slit air sampler for 10 to 20 min. The total viable count (TVC) per liter of air was calculated for each sample following incubation at 30°C for 24 h. Monthly samples were collected on the hide removal floor and the carcass dressing floor from March 1998 to April 1999. Mud tag, dirt, and wetness of incoming hides were scored subjectively on the hide removal floor. The other processes were sampled in 3 separate months. The TVC at two locations on the hide removal floor (center of hide removal floor [CHF] and top of hide puller [THP]) had a strong association to each other (r = 0.84; P < 0.001). The mean TVC at the CHF and THP was 10.0 and 11.5, respectively, and the TVC for individual samples ranged from 2 to 42 at these locations. The TVC means for all the other processes ranged from 0.01 to 0.7. Tag and TVC on the hide removal floor had a different seasonal distribution with TVC being highest in the warm months (April to October 1998) and lowest for November to April 1999. No significant relations between TVC and the dirt and wetness variables were evident for the CHF and THP locations on the hide removal floor. It was concluded that the control of aerosols in the hide removal floor should be treated as a critical control point in the HACCP plan.

Three-dimensional reconstructions of indoor environments are useful in various augmented and virtual scenarios. Creating a realistic virtual apartment in 3D manually does not only take time, but also needs skilled people for implementation. Analyzing a floor plan is a complicated task. Due to the lack of engineering standards in creating these drawings, they can have multiple different appearances for the same building. This paper proposes multiple models and heuristics which enable fully automated 3D reconstructions out of only a 2D floor plan. Our study focuses on floor plan analysis and definition of special requirements for a 3D building model used in a Virtual Reality (VR) setup. The proposed method automatically analyzes floor plans with a pattern recognition approach, thereby extracting accurate metric information about important components of the building. An algorithm for mesh generation and extracting semantic information such as apartment separation and room type estimation is presented. A novel method for VR interaction with interior design completes the framework. The result of the presented system is intended to be used for presenting a large number of apartments to customers. It can also be used as a base for purposes such as furnishing apartments, realistic occlusions for AR (Augmented Reality) applications such as indoor navigation or analyzing purposes. Finally, a technical evaluation and an interactive user study prove the advantages of the presented system.

Bu33333333ilding with irregular floor plan has the eccentricity of force to the centre of building isappears to be more susceptible to deformation and damage when subjected to earthquake movements than with regular floor plan. This study aims to determine the seismic performance of buildings with the irregular floor plan in displacement and drift by service and ultimate performance limit.The object of research is Padang Pariaman public works office building. The evaluation method used non-linear static analysis(Pushover) which is one method to evaluate the seismic performance of the building.Pushover analysis performed by providing a static load in the lateral direction gradually to achieve a specific displacement target. This research is based on SNI-1726-2012, ATC-40 and FEMA 356. The results of the analysis show that the maximum lateral force of 10909.9 kN occurs in step-6 pushover analysis with a displacement of 0.165 m, maximum drift = 0.0705 m and maximum in-elastic drift = 0.025 m.This means the building is included in the IO (Immediate Occupancy) performance level. Although there is damage from small to medium level, still has a big threshold against the collapse, which means the building is safe against the earthquake.

Abstract The presented paper deals with an analysis of the legislative, hygienic, functional and operational requirements for the design of detached houses and individual dwellings in terms of typological requirements. The article also presents a sociological survey about the preferences and subjective requirements of relevant public group segments in terms of living in a detached house or an individual dwelling. The aim of the paper is to define the possibilities for the optimization of typological requirements. The optimization methods are based on principles already applied to contemporary detached house preferences and trends. The main idea is to reduce the amount of floor space, thus lowering construction and operating costs. The goal is to design an optimized floor plan, while preserving the hygienic criteria for individual residential dwellings. By applying optimization methods, a so-called rationalized and conditioned floor plan results in an individual dwelling floor plan design that can be compared to a reference model with an accurate quantification comparison. The significant sources of research are the legislative and normative requirements in the field of house construction in Slovakia, the Czech Republic and abroad.

The European seismic code 8 (Eurocode 8) classifies buildings as planwise regular according to four criteria which are mostly qualitative and a fifth one, which is based on parameters such as stiffness, eccentricity, and torsional radius, that can be only approximately defined for multistory buildings. Therefore, such plan-regularity criteria are in need of improvement. ASCE seismic code, according to a different criterion, considers plan (or “torsional”) irregularity in a building when the maximum story drift, at one end of the structure, exceeds more than 1.2 times the average of the story drifts at the two ends of the structure under equivalent static analysis. Nevertheless, both the ASCE approach and the threshold value of 1.2 need to be supported by adequate background studies, based also on nonlinear seismic analysis. In this paper, a numerical analysis is carried out, by studying the seismic response of an existing R/C school building taken as the reference structure. Linear static analysis is developed by progressively shifting the centre of mass, until the ratio between the maximum lateral displacement of the floor at the level is considered and the average of the horizontal displacements at extreme positions of the floor at the same level matches and even exceeds the value of 1.2. Then, nonlinear dynamic analyses are carried out to check the corresponding level of response irregularity in terms of uneven plan distribution of deformation and displacement demands and performance parameters. The above comparison leads to check the suitability of the ASCE approach and, in particular, of the threshold value of 1.2 for identifying buildings plan irregularity.

It further explains how Velázquez, by means of geometric composition, achieved double centrality and why nearly half of those who look at his masterpiece perceive that the point of view is opposite the mirror. The spatial analysis of the floor plan confirms that, according to the law of reflection, the image in the mirror is coming from the large canvas. The correct floor plan follows from the Renaissance perspective system, and its understanding leads to further revelation of its universal use.

Full textAbstract:
This article presents the findings of a study on assessment of the increase in building’s response due to accidental torsion when subjected to seismic forces. Critical stiffness and geometrical parameters that define buildings torsional response are examined including: (1) the ratio, Ω, between uncoupled torsional frequency ωθ to uncoupled translation frequencies in the direction of ground motion ωx or ωy, (2) floor plan aspect ratio, b/r, which is a function of the floor dimension and radius of gyration. The increased response is assessed on symmetric multi-storey buildings using both static and dynamic analysis methods specified by ASCE-7 and considering parameters affecting the torsional response. It was concluded that static and dynamic analysis procedures predict different accidental torsion responses. Static analysis based on the Equivalent Lateral Force (ELF) method predicts more conservative accidental torsions responses for flexible structures with Ω < 0.7~0.80, while the responses are less conservative for stiffer buildings. The conservativism in static analysis method is attributed to the response amplification factor, Ax. Floor plans and their lateral support system having frequency ratio Ω = 1 will also have a torsional radius equal to radius of gyration, and will experience drop in torsional response relative to more torsionally flexible buildings. This article presents a procedure to overcome the shortcomings of static and dynamic analysis procedures in terms of estimating accidental torsion response of symmetric building structures.

In the 16th century the Society of Jesus built a large number of churches following the Tridentine model of a Latin cross and a single nave. However, the shift towards this model did not entail the abandonment of the central floor plan, especially in the 17th century. The acoustics of these spaces can present phenomena linked to focalizations which increase the sound pressure level. The church of San Luis de los Franceses, built by the Jesuits for their novitiate in Seville (Spain), is an example of a Baroque church with a central floor plan. Although the church has hosted different congregations since its inauguration it is currently desacralized and used for theatres and concerts. The acoustics of this church were studied by the authors through in situ measurements and virtual models. The main objective was to analyse the evolution and perception of its sound field from the 18th to 21st centuries, considering the different audience distributions and sound sources and the modifications in furniture and coatings. Analysis of the evolution of its sound field shows that the characteristics have remained stable, with a notable influence of the dome on the results for the different configurations studied.

The shape of a building largely contributes to its energy consumption. The current study utilized metrics of surface-to-volume ratio, surface-to-floor ratio, area-to-perimeter ratio, and volume ratio to evaluate building energy performance. Also, the paper focused on the relation between the air-conditioned room and non-air-conditioned room. This approach affects both the design stages of the floor plan and the main designing factors that decide which spaces would become air-conditioned spaces such as those mostly occupied by residents or non-air-conditioned space such as staircases and elevators. The heating load and cooling load were calculated using the new equation based on the location of non-air-conditioned spaces and envelope ratio facing the outdoor. Both the width-depth ratio and envelope ratio were analyzed using the IES_V.E (Integrated Environmental Solutions Virtue Environment) program. It turns out that, as the non-air-conditioned spaces increase, both heating load and cooling load were reduced.

Reinforced concrete buildings utilizing structural walls for lateral load resistance are the predominant form of construction in Chile for buildings over four stories. Typical buildings include a large number of walls, with ratios of wall cross-sectional area to floor plan area of roughly 3% in each principal direction. Based on the good performance of RC buildings in the March 1985 earthquake, requirements for closely spaced transverse reinforcement at wall boundaries were excluded when Chile adopted a new concrete code in 1996 based on ACI 318-95. In recent years, use of three-dimensional linear models along with modal response spectrum analysis has become common. Since 1985, nearly 10,000 new buildings have been permitted. Although the newer buildings have similar wall area to floor plan areas as older buildings, newer walls are thinner and buildings are taller, leading to significantly higher wall axial load ratios.

Aiming at the floor heave of transportation concentrated roadway on the West Wing (TCRWW) of No. 1 Coal Seam in Danhou Mine, it affects underground coal transportation and mine safety production. First, the lithology and structure of the roadway floor were sampled and tested, and it was found that it contained clay minerals with high hydrophilicity. Secondly, starting from the mechanical mechanism of the roadway floor, a mechanical model of the roadway floor is established. By increasing the floor anchoring layer thickness m1, the floor deformation can be effectively controlled to guarantee the stability of the surrounding rock of the roadway. Thirdly, the FLAC3D numerical simulation analysis of the roadway deformation under the existing support scheme of the roadway is consistent with the measured deformation results on-site, thereby revealing that the existing support scheme and parameters are not reasonable. Finally, the unreasonable support scheme and parameters of the existing roadway were disclosed, and an antifloor arch structure was proposed: “quicklime bottom paving + prestressed anchor cable + concrete arc beam + metal mesh + C20 high-strength concrete filling.” This floor treatment plan is adopted for the industrial verification of the test section of TCRWW. Engineering practice shows that the optimized roadway support scheme has a better effect on the deformation control of the roof-to-floor and rib-to-rib, thereby effectively ensuring safe and efficient production in the mine.

This Paper aims to analyze the performance level of Pasar Butung post-fire on December 15, 2010. The fire was centered on the 1st and 2nd floor. Data retrieval include visual observation, carbonation test, concrete hammer test, concrete core test and tensile test of steel reinforcement that was held on January, 2011. All data that was taken will use to analyze the structure. Observations indicate that the temperature of the fire around 400oC. Beams and columns on floors 1 and 2 had cracks and the quality of concrete fell 62% from 21.15 MPa to 14 MPa at the outer cross-section. While the floor plates 2 and 3 having a width of cracks and residual concrete quality is only 11.57 MPa. Pushover analysis (static lateral load) is a nonlinear static analysis that can provide detailed information about the collapse behavior of structures against earthquake loads, while the performance point is the magnitude of the maximum displacement of the structure during an earthquake plan. Results of 3D nonlinear static pushover analysis on the structure of Pasar Butung shows that performance point is achieved when the base reaction V reach 484.97 tons with displacement of 0.021 m (2.1 cm) at step 3. Results of analysis showed that the performance of the structure is still within the limits of Life Safety.

The frame construction of an apartment complex that consists of multiple buildings encounters various uncertainties, owing to the complex relationships between units of work. Currently, the period of such a construction is calculated based on the number of floors of the highest building in the complex. This study quantitatively analyzes an apartment frame construction period using a queue model and evaluates the validity of the estimated period. In this regard, a methodology is proposed for analyzing the construction period by applying the concept of a customer and a server. A case study on the duration of an apartment frame construction period is conducted with the Korea Land and Housing Corporation, which has supplied the largest number of apartments in South Korea. It was found that the stable state of a queue system was observed when the rate of server utilization was applied to the basement and above-ground floors. However, a stable state was not reached on the ground floor. This study includes non-working days in its calculation and quantitatively analyzes uncertainty factors during construction. Therefore, the findings can be practically utilized to quantitatively plan the durations of work units in an apartment frame construction.

Wireless networks in a room are strongly influenced by interference. To overcome the interference and so that the performance from the wireless network is getting better, then optimization is done. There are several types of propagation that can interfere with the performance of wireless networks, which include the number of transmitters (access points), free space loss, Received Signal Strength (RSSI), coverage that can be served, measuring attenuation on barriers (concrete walls, soft partitions, doors, and floors).This research is an analytical study where the purpose of this study is to determine the position of access point a good in the Shari'ah Faculty Building and the Law using the method of Bayesian probability. The first stage of this research is to determine the distance of the signal reception to find out the strength of the signal with manual random sampling so that the data obtained varies. The second stage is to determine the position of the access point with a choice of several points so that the best position can be compared based on the plan of the Syari'ah Faculty and Law Building. The last step is calculating probability by the method of Bayesian probability.The results of this study are the position of the access point best on the 3rd floor, namely at position B with a probability value of 13 while on the 4th floor the position of access the point best in position A with a value of 10, position D with a value of 13 and position E with a value of 13.

To successfully implement a hazard analysis critical control point plan, prerequisite programs are essential. Sanitation standard operating procedures are an important part of such a plan and can reduce contamination levels so that food safety and quality are not adversely affected. Noncontact surfaces in the shell egg processing plants can serve as a reservoir of cross-contamination. The objective of this study was to assess the efficacy of sanitation programs used in a variety of shell egg processing facilities (in-line, off-line, and mixed operations). Fourteen different noncontact surfaces were sampled in nine commercial facilities across the southeastern United States. Non–egg-contact surfaces were defined as those where the shell egg does not come into direct contact with the surface or with the fluid from that surface. Gauze pads soaked in sterile phosphate-buffered saline were used for sampling at the end of a processing day (POST) and again the next morning prior to operations (PRE). Aerobic plate counts (APCs) and numbers of Enterobacteriaceae were determined. No significant differences (P > 0.05) were found between POST and PRE counts for either population recovered from the 14 sampling sites. Only samples from the floor under the farm belts, nest-run loader, washers, and packer heads were reduced by 1 log CFU/ml of rinsate for APCs or Enterobacteriaceae counts. APCs of more than 104 CFU/ml of rinsate were recovered from many samples. Highest APCs were found on the floor under the farm belt and on shelves of the nest-run carts. High APCs were found on the wheel surface for off-line carts and on the loading dock floor. Highest Enterobacteriaceae counts were found in samples from the floor, drain, and nest-run egg cart shelves. A lack of significant difference between POST and PRE counts indicates that current sanitation programs could be improved. These data suggest that traffic patterns for the movement of eggs and materials through the plant should be reevaluated so that cross-contamination is reduced.

Full textAbstract:
Τwo new documented non-linear static (pushover) procedures on asymmetric single-storey R/C buildings are presented in detail herein, aiming directly at the Near Collapse state. Both procedures apply relative to the “Capable Near Collapse Principal reference system” of the single-storey building. The main objective of the two proposed procedures is to fully consider the coupling between torsional and translational vibrations of the floor-diaphragm under translational seismic excitation of the building’s base. The first pushover procedure, which is a Direct Displacement-Based one, uses floor enforced-displacements as action. In the second pushover procedure, which is a Force-Based one, the floor lateral static forces are applied eccentrically to centre of mass using suitable inelastic design eccentricities (dynamic plus accidental ones). The floor enforced-translations/rotation and the appropriate inelastic dynamic eccentricities used in the two proposed procedures derive from extensive parametric non-linear response history analysis and are given by figures or equations. In order to clarify in detail and evaluate the new pushover procedures, a torsionally-flexible, double-asymmetric, single-storey R/C building is seismically assessed. The validation of both procedures relative to the results of non-linear response history analysis shows that both predict with safety the in-plan displacements of the building.

The purpose of the study is to identify the main typological, space-planning, constructive, stylistic and town-planning features of residential buildings designed by the Municipal union of Novosibirsk housing cooperatives in the years of the first five-year plan. Research objectives: 1) To substantiate the need for a transition to stone construction and the benefits of the development of quarterly residential buildings in Novosibirsk during the first five-year plan; 2) Determine the main types and types of housing, the development of which was engaged Gorshilsoyuz in the study period; 3) Analyze the most characteristic objects designed by Gorzhilsoyuz in the 1930s. The method of work is based on a comprehensive analysis of archival materials from the Novosibirsk State Archive (GANO) and funds of the Museum of the History of Architecture of Siberia named after S.N. Balandin (Novosibirsk), as well as literary sources and materials of periodicals. The novelty of the research lies in the fact that for the first time, based on an analysis of residential building projects created by the Gorzhilsoyuz, their architectural and typological features and compositional and stylistic features are identified and compared in detail. Founded in 1925, the Municipal union of Novosibirsk housing cooperatives (Gorzhilsoyuz) began its activities with the design of wooden residential buildings for housing cooperatives. In the years of the first five-year plan, this organization switched to the design of stone multi-apartment residential buildings based on socialist type housing principles. If in the previous period, most residential buildings had a unified space-planning solution, which did not include other functions besides housing, in 1928–1932 the city began to embody the original projects of new types of not only multi-family buildings, but also quarterly residential complexes, which included in their structure public housing and service facilities. The first example of a quarter residential development of the city was the “garden-quarter of a new type” of the housing cooperative “Pechatnik”. The design of residential buildings involved professionals Gorzhilsoyuz. The corner multisection apartment building had in the ground floor: shops, a dining room, a pharmacy, a kindergarten, a red corner; in the basement were: showers, bathrooms and laundry. Decorative belts and rizalits were the main architectural elements of the main facade. In 1929–1930 housing cooperatives “Medrabotnic” and “Khimik” built two corner multi-section residential buildings according to the projects of the Gorzhilsoyuz. Multi-apartment building “Medrabotnic” consists of four sections. Standard ordinary end sections had two apartments on the floor: three- and four-room apartments, each of which housed a kitchen, a bathroom, and a bathroom. A store was designed on the first floor of the rotary section, and on each floor above are two three-room apartments (without bathrooms) and one four-room (second to fourth floor) apartments. The residential building of the “Khimik” was the first five-story building in Novosibirsk and was conceived as a communal house. The house provided separate sleeping areas for: adults and children. However, due to the change in the ideological line of the government, the project was converted into an apartment building with shops on the ground floor. The facades of the house spatially overlap with the facades of the building “Medrabotnic”. The residential four-storey building of the housing cooperative “Rabochaya piatiletka”, built in 1930 according to the drawings of the Gorzhilsoyuz, was designed as a communal house. The project was supposed to accommodate people in separate age groups. On the ground floor there was a dining room with a kitchen, administrative rooms and bedrooms for the elderly. On the second floor there were the bedrooms of adults and children of eight years of age. The third and fourth floors were occupied by bedrooms of adults and children up to 16 years. Half of the fourth floor had social functions. The basement was allocated for laundry, boiler room and pantry products. However, in connection with the Decree of the Central Committee of the CPSU (b) “On work on the restructuring of life” (dated May 16, 1930), the dormitory was re-planned, and later became an administrative building.

In tropical countries, there is a need for air conditioning systems, especially for high-rise buildings to provide comfort for their residents. For this reason, it is necessary to plan an air conditioning system using a ceiling duct with a VRV / F (Variable Refrigerant Volume / FLOW) system setting so that the load and capacity are appropriate and more efficient. In calculating the cooling load, starting from the sensible load and the load, and calculating the size of the ducting. The research method used to plan an air conditioning system using a ceiling duct with VRV / F system settings is the observation method by taking the required data. Perform calculations and analysis with the data obtained. So that after planning the total load on the 5th floor = 270,752.79 Btu / hr (79.3498kW), the 6th floor = 280,568.37 Btu / hr (82,227 kW), and the 7th floor = 229,690.66 Btu / hr (67.3157kW). The size of the ducting supply used is: Height = 75mm-450mm, Width = 75mm - 450mm and the size of the ducting return used is Height = 75mm-450mm, Width = 75mm-450mm. From the planning results, it is determined that the air conditioning system uses a ceiling duct system with VRV / VRF system settings. The advantages are Easy Maintenance, high reliability, large capacity use, space-saving design, different indoor units in one system, and using R410 type refrigerant.

The improvements in (3D) three–dimensional underlying examination and processing assets have permitted the effective and safe plan of taller constructions. These constructions are the outcome of expanding metropolitan densification and financial suitability. The pattern towards continuously taller constructions has requested a move from the conventional strength based plan approach of structures to an emphasis on obliging the general movement of the design. Presently a day's supported cement (RC) divider outline structures are generally suggested for metropolitan development in zones with high SE danger. Presence of shear dividers bestows an enormous solidness to the sidelong power opposing arrangement of the RC building. Appropriate specifying of shear dividers can likewise prompt bendable conduct of such constructions during solid quake shaking. One of the remarkable boundaries impacting the shear divider (SD) SE (SE) conduct outline structures is the SD region proportion. In this manner a scientific examination is performed to assess the impact of Shear Wall Area to floor zone proportion (SW/FZP %) on the SE conduct of multistoried RC structures with delicate story at ground floor. For this reason, 12 structure plans that have Five, Eight and Twelve stories with SW/FZP % going somewhere in the range of 0.70% and 1.31% in the two ways are created. Here, the conduct of these plans under quake stacking is evaluated via doing Response Spectrum Analysis and Linear Time History Analysis utilizing primary examination programming E-TABS. Reaction Spectrum Analysis is finished by SE code IS 1893:2002. Straight Time History Analysis is completed by considering the three ground movement records to be specific Bhuj, Chamba and Uttarkasi. The primary boundaries considered in this investigation are the connection SW/FZP % has with base shear and rooftop dislodging, story uprooting and story float. The logical outcomes demonstrated that building plans with SW/FZP % equivalent to 1% acted sufficiently under tremor loads. Furthermore when the SW/FZP % expanded past 1% it is seen that the improvement of the SE presentation isn't as huge.

The paper describes space-planning and structural concept in source-efficient buildings that provides multiple functions of the rooms and large-span space.The main load-bearing structures of two adjacent storeys are metal trusses with parallel chords between which (between top and bottom chords) intermediate storeys are designed and the space between trusses is occupied by the free plan storeys. Bottom and top chords of the truss resist together with floor structure forming two-storey steel-reinforced concrete unit. To calculate value of deformation capacity for nodal connection a numerical experiment focused on modelling a part of building from solid finite elements has been performed. The results of performed analysis are the average values of stiffness of nodal interface of solid floor slab on corrugated deck and truss chords for finite elements KE 55 of typical layout (of flat finite elements). The obtained average values of stiffness were introduced into structural design of flat finite elements. Taking into account flexibility of floor slab that supported by middle trusses for the given structural concept leads to decreased span bending moments and increased support bending moments by 25% compared with hinge support of floor.

This paper introduces an automated image processing method to analyze an architectural floor plan database. The floor plan information, such as the measurement of the rooms, dimension lines, and even the location of each room, can be automatically produced. This assists the real-estate agents to maximise the chances of the closure of deals by providing explicit insights to the prospective purchasers. With a clear idea about the layout of the place, customers can quickly make an analytical decision. Besides, it reduces the specialized training cost and increases the efficiency in business actions by understanding the property types with the greatest demand. Succinctly, this paper utilizes both the traditional image processing and convolutional neural networks (CNNs) to detect the bedrooms by undergoing the segmentation and classification processes. A thorough experiment, analysis, and evaluation had been performed to verify the effectiveness of the proposed framework. As a result, a three-class bedroom classification accuracy of ∼ 90% was achieved when validating on more than 500 image samples that consist of the different room numbers. In addition, qualitative findings were presented to manifest visually the feasibility of the algorithm developed.

Excavation and observations from 1984–6 on the Leadenhall Court site in the City of London revealed elements of the fifteenth-century market building known as ‘The Leadenhall’. The truncated foundations were located in various areas of the site; 177 medieval moulded stones were found reused in later cellar walls; and a fragment of the west wall survived to its full height of 11.17m encased between Victorian buildings. The recording and subsequent study of these features, together with a reassessment of such plans and drawings of the building as have survived, established the ground plan of the quadrangle and chapel, and made possible a complete reconstruction of the north range of this important civic building. The methodology used in the reconstructions is described with particular emphasis upon the analysis of the moulded stones. In conclusion, both the design of the structure and the documentary sources are studied to show how it may have been intended to function.The arcaded ground floor functioned as part of a common market, while the upper floors were intended to be a granary. For convenience, however, this dual-purpose building is referred to as the ‘garner’ throughout the text.

Full textAbstract:
This paper presents an approach to build a spatial database for indoor environments. It will be presented the main requirements for the implementation of an object-relational database for the representation and analysis of indoor environments, which considers the solutions for both type of representations, floor plan and schematic map. These representations consider the high number of information found in an indoor environment and the fact that they are disposed in different floors of the structure. The relationship between objects and their attributes defines the links and restrictions between them. Hence, the model should describe the entities and their interrelationships, as well as the attributes of the elements and their characteristics. After the database was developed, it was implemented an algorithm that calculates routes between points in the indoor environment, considering not only the shortest distance but also the floor change. The model was tested by Antunes and Delazari (2019) using an application and some interviews with users to evaluate the elements included in the database considering a navigating task. Some results pointed out the need to insert new information in the database regarding physical characteristics (color, material) of elements found in the indoor environment to assist users during orientation and navigation tasks. Moreover, it is necessary to include elements from the outdoor environment used as reference points in the cartographic representation.

Full textAbstract:
In this study, analysis and evaluations were carried in order to determine the optimum conditions of reinforced concrete mansard roof applications. In total 96 mansard and 24 non mansard structure analysis were performed. The constructed models are symmetrical from all directions and it is modeled under the minimum conditions allowed by the regulation. As the column span, the distance between the columns was determined as 4 meters. The span conditions were determined as 3 spans, 4 spans, 5 spans and 6 spans by evaluating the parcel sizes and zoning conditions. Thus, a total of 120 calculation models were created. The base shear force, column moments and the maximum top displacement values were discussed in concordance with these calculations. As a result of the analysis, the graphical values of the mansard buildings were examined along with the non mansard buildings from the 3rd floor to the 8th floor, according to the zoning plan. In this study, graphs of parcels, span values and the number of storeys were drawn by keeping the values constant, and evaluations were made on the same graphs with and non mansard. In addition, by looking at the movements of the graphs obtained from this study on the same series, equations were adapted to the graphs and the series created with these equations were expanded and stochastic parabolic cones were formed at the shear force for 10 storeys, in the column moments. The mean values for the top displacement chart were taken and when the 20-storey displacement value was placed on this curve, it was determined that it appeared at a point very close to the estimating equation curve. Based on the analysis results, it is understood that it is possible to create a set of estimations for different number of storeys and plans.
