Full textAbstract:
The main cause of defects and damage to balcony plates can be considered the so-called temporary factor, which has a far from positive effect on the general state of the structure - the impact of atmospheric-sphere precipitation, strong temperature differences. In addition to the temporary factor, the destruction of the balcony slab can be influenced by mistakes made during installation, no drains and overstrain of the balcony slab due to excessive load on it, which causes the formation of cracks. The basis for the survey was the check of the technical condition of the balcony slabs of a three-story multi-storey brick residential building in order to determine the degree of wear, possible defects and assess the possibility of further operation of the slab. A structural solution analysis was carried out to assess the technical condition of the building structures. Loads acting on the structures, impacts and operating conditions, the quality of structures, materials and connections were established. This also took into account factors such as the geometric dimensions of structures and their sections; presence of cracks, splits and destruction; condition of protective coatings; broken adhesion of reinforcement to concrete; presence of reinforcement rupture; condition of anchoring of longitudinal and transverse reinforcement; degree of corrosion of concrete and reinforcement. As a result of visual and measuring control, defects and damages having the requirements of operation and leading to a malfunction of the structure were revealed. The results set forth in the article may be of interest to specialists of expert organizations who are engaged in the examination of residential apartment buildings in order to assess the actual state of bearing structures, in particular balcony slabs

The application of structural insulated panels (SIP) was mainly limited to wall panels in the past. In order to evaluate the flexural performance of SIP two-way slabs, an experimental research on the flexural behavior of four full-size two-way slabs, made of SIP panels or fiber reinforced structural insulated panels, was presented in this paper. The bending capacities and the strains in the face layers were studied and compared with those of ordinary reinforced concrete two-way slabs. Testing results verified that, strengthening of glass fiber reinforced polymer sheets could obviously improve the flexural capacity of SIP slab. Fiber reinforced structural insulated panels could substitute ordinary reinforced concrete slabs in residential or light commercial buildings.

Постановка задачи. Изучение прочности и трещиностойкости сборных плит перекрытий при аварийных воздействиях в результате взрывов газовоздушной смеси в помещениях жилых зданий. Результаты. Выполнена оценка прочности и трещиностойкости сборных плит при взрывных воздействиях. Даны рекомендации по изменению схемы армирования типовых плит перекрытий жилых зданий для обеспечения их сохранности и пригодности к дальнейшей нормальной эксплуатации после воздействия внутренних дефлаграционных взрывов газовоздушной смеси. Выводы. Путем расчетов с использованием предложенной модели установлено, что стойкость сборных междуэтажных перекрытий жилых зданий к внутренним взрывам газовоздушной смеси в общем случае не обеспечена. Необходимая прочность и трещиностойкость может быть достигнута путем изменения схемы армирования типовых железобетонных плит без изменения их конструкции и технологии изготовления. Statement of the problem. The strength and crack resistance of prefabricated floor slabs under emergency impacts as a result of explosions of the gas-air mixture in the premises of residential buildings are investigated. Results. The strength and crack resistance of prefabricated slabs under explosive impacts have been evaluated. Recommendations are provided for changing the scheme of reinforcement of standard floor slabs of residential buildings to ensure their safety and suitability for further normal operation following the exposure to internal deflagration explosions of a gas-air mixture. Conclusions. By means of calculations using the suggested model, it was found that the resistance of prefabricated interfloor floors of residential buildings to internal explosions of the gas-air mixture is generally not ensured. The required strength and crack resistance can be achieved by changing the reinforcement scheme of typical reinforced concrete slabs without changing their design and manufacturing technology.

The research and analysis of technical conditions, deflections, and bearing capacity of subjected to fire impact reinforced concrete slabs of raised “panel per room” typical design model 1-480a of a five-storey residential building in Lviv are present. A study of the technical condition of floor structures in the area of high temperatures. In the area of intense fire a decrease in the bearing capacity and rigidity of the shelf of the tent floor slab under the action of high temperatures was found. Due to the fire impact, the thin plate of raised panel slabs completely loses load-bearing capacity, with large sagging deflections, caused by the plastic elongation of the wire reinforcement due to the action of high temperature. The developed design of the reinforcement of the riced plate slab is considered.

Full textAbstract:
In order to promote the usage of structural insulated panels (SIP) as floor and roof for residential buildings, the bending capacity of SIP should be improved. In this paper, fiber reinforced polymer sheets were used as strengthening materials. The new variation of SIPs, which is called Fiber Reinforced Structural Insulated Panel (FSIP), was tested in this paper. Five one-way slabs were subjected to uniformly distributed loads till failure. It is observed that the flexural bearing capacity and stiffness of the slabs were affected by the thickness of foam core and the strength of FRP sheet. By strengthened with FRP sheets, the one-way slab of structural insulated panel can be used for floor and roof in residential and light commercial buildings.

Full textAbstract:
A comprehensive study of the operational reliability of reinforced concrete structures of residential buildings includes an analysis of design documentation, inspection of the site, strength and deformation tests, and an assessment of the impact of the environment. This allows you to identify defects, determine the current condition and reliability of structures, and identify elements that require repair or replacement. The key aspects are the characteristics of the structures, expected operational loads and the impact of external factors. An integrated approach ensures a comprehensive assessment of the condition and reliability of reinforced concrete structures. A comprehensive survey of the technical condition of reinforced concrete structures (foundation and floor slabs) of a five-story residential building was carried out in accordance with SP RK 1.04.101-2012. It was found that the structures are in good condition, but some defects were identified that require compliance with the rules of technical operation. The conducted survey of the reinforced concrete structures of the five-story residential building made it possible to assess their technical condition. The foundation and floor slabs are in good condition, without serious defects. However, some minor defects have been identified, such as hairline cracks in the slabs, which do not affect the load- bearing capacity. To ensure the durability of the structures, compliance with technical operation rules is required.

Works execution organization at reconstruction and renovation of residential and public buildings after the fire for embedded systems with usage of slabs lifting method at restrained urban conditions were considered. The paper suggests usage features of the slabs lifting method at building reconstruction conditions after the fire. The technology of reconstruction with the usage of slabs lifting method allows to practically refuse the use of lifting cranes and to reduce significantly (up to 50%) the required building area compared with the lifting crane construction methods of embedded structures. It allows to perform the reconstruction without restriction of traffic on adjoining streets and to perform construction in restrained urban conditions.

The authors consider objects of large-panel residential buildings, namely floor slabs, in this study. In view of the fact that the existing design of the slabs was carried out according to the old technical and regulatory documentation to comply with the requirements of modern regulatory documents «StroyPanelKomplekt» proposed new design solutions for the floor slabs of 97 series. The main design features of the slabs after the change in design solutions are: increased cross-sectional area of the working reinforcement (from 6 mm to 8 mm), increased concrete protective layer up to 25 mm. Therefore, before the start of mass production of these slabs, full-scale tests were carried out by «StroyPanelKomplekt» together with the department «Construction production and geotechnics» of PNRPU. The tested slab P3-6-501 is a floor element for large-panel residential buildings of the 97th series. The slab in the building is supported on four sides by internal and external wall panels, concrete design class B15. The design class of the working fittings is A400. During the tests, the indicators necessary for assessing the strength, stiffness and crack resistance, as well as the nature of destruction were controlled, including: the values of the loads causing the controlled limit state; product deflections; crack opening width. To measure the deflections, we used measuring instruments and instruments with a scale division of 0.01 mm, namely, 6PAO deflection meters. To measure the width of the crack opening during the tests, an MPB-2 microscope with a scale of 0.05 mm was used. The test results are presented in this article.

This paper aims at advancing on the validation of indicators of building concrete frames' sustainability from an integrated, life cycle perspective. A case study approach investigates (i) feasibility of comparing sustainability performance of different flooring systems; and (ii) similarity between environmental indicators trends for a typical flooring system and corresponding whole superstructure. Three residential buildings are analyzed, using either prestressed concrete flat (PCF) slabs or reinforced concrete waffle (RCW) slabs and flat beams exposed to a marine environment. SimaPro 7.3 supports calculation of the environmental indicators. Service life estimation is used to ensure functional equivalence and to form a basis for life cycle costing. PCF slabs showed best functional/technical and economic results but were outperformed by RCW slabs' environmental results. Most environmental indicators showed the same trend for both typical floor and whole superstructure.

Full textAbstract:
The paper deals with strengthening structures against punching shear with focus on strengthening of existing concrete foundation slabs. These can be slabs of basements of residential, administrative and other buildings. Also, foundations slabs placed on piles can be considered. This is very specific case of strengthening where only one surface of the structure is accessible. Strengthening is often designed using massive new bearing elements, which are space-demanding. Attention is paid to the development of technology that minimizes the resulting constraints on the surrounding area and is sufficiently effective. Inspiration is strengthening of ceiling flat slabs with additional shear reinforcement. Compared to the ceiling slabs, a larger load must be bear to the foundation structures and therefore the shear reinforcements demand larger dimensions. Mechanical expanded anchors are used for anchoring on the inaccessible side. A significant contribution of mechanical anchoring is demonstrated in the tests results which make possible more efficient design of additional punching reinforcement.

Full textAbstract:
Lebanon is one of the countries which are at high risk of experiencing rock falls. In order to ensure public safety, engineers must take into consideration this risk. In the past years, numerous researches were conducted on the behavior of horizontal structural elements, slabs, of different types under dynamic impact load. Reinforced concrete flat slabs are commonly used slabs in residential buildings. To build a profound understanding of the structural behavior of the slabs under such loadings, it is important to investigate the effect of energy dissipation on the equivalent impact force, mid-span deflection and damage pattern. In this study a sample reinforced concrete slab of 500 x 1000 x 100 mm dimensions is considered. The aim of this paper is to find how these factors vary with the increase in energy as the drop load resembling the real rock fall is left to drop freely from different heights 0.6 m and 1 m.

Full textAbstract:
Floor slabs are one of the integral load-bearing elements in buildings. When it comes to their serviceability limit state (SLS), one of the key aspects is their dynamic behaviour. In case of residential or administrative buildings, the knowledge of dynamic behaviour of slabs is important in terms of hygiene (psyche) of the user. When speaking of buildings such as medical facilities or laboratories that are using delicate machinery, the knowledge of the dynamic behaviour is important in order to prevent vibration induced damage to given machinery. Therefore, the aim of this paper is to provide a brief overview of standards applicable for assessment of dynamic behaviour, present various methods for calculation of first natural frequency, as well as to present outlines for in-situ measurements, all with special regard to voided slabs.

Full textAbstract:
Construction of cost effective houses is a dilemma among the impoverished population in developing countries. The ever increasing price of traditional building materials results in high capital investments for residential buildings. Palmyrah is a significant economic resource, widely spread all over the northeast region of Sri Lanka. This research explores the technical feasibility of using heartwood of Palmyrah as a reinforcing member in lightly loaded concrete elements. Initially, mechanical properties of Palmyrah were examined through static bending, tensile, and compressive tests. Percentages of water absorption, dimensional stability, and anchorage bond strength were investigated to envisage the suitability of Palmyrah as reinforcement. Next, several short span slabs and beams reinforced with Palmyrah strips were subjected to tests. It was observed that Palmyrah reinforcement enhanced the moment capacity of the slabs and beams compared to unreinforced sections. Experimental failure loads of slabs and beams were higher than theoretically predicted values with Palmyrah reinforcement. Further, Palmyrah reinforced beams and slabs underwent flexural failures. Thus, it is concluded that heartwood of Palmyrah has the potential to be used as reinforcement in lightly loaded slabs and beams. Further research is recommended to investigate the durability and serviceability issues.

As mass timber construction becomes more widely adopted, there is an incentive to use thinner, lighter panels. Research sponsored by the American Wood Council and WoodWorks explores the relative performance of 5-ply CLT and 5-ply equivalent panels to 3-ply CLT and 3-ply equivalent panels both bare and with topping slabs. In addition to the comparison of thicker and thinner panels, assemblies using resilient mats and gypsum concrete topping slabs were also developed to meet the IBC residential code minimum performance. Results and acoustic analysis will be presented along with a discussion of the non-acoustic considerations of the move to thinner mass timber structural panels.

The deterioration or ageing of the existing infrastructures coupled with increased safety requirements necessitate immediate strengthening. Developing long lasting and cost effective repair techniques and materials continue to capture the attention of concrete professionals worldwide. The main purpose of this investigation was to extend the life span of a multi-storey precast reinforced concrete structure built in Riyadh 40 years ago. The condition assessments relied on analytical tools, visual, field and laboratory experiments for core samples collected from the building. The analytical checks of the building revealed considerable deflections of some slabs because of design error. The field and chemical analysis tests performed, confirmed the occurrence of durability defects as a result of poor workmanship during the construction stage. Several state-of-the-art repair techniques and materials were used for enhancing the service life of the structure at a minimum cost. The Repair strategy implemented included, removal of the deteriorated concrete, pouring a bonding agent on the surface of the damage, followed by injecting high strength cementitious grouts, supporting the deflected slabs using I-section steel beams, using cathodic protection to prevent corrosion, strengthening the columns and beams using carbon fiber reinforced polymer (CFRP) sheets, and steel jackets.

This paper presents various case studies of examined and calculated live loads on reinforced concrete structures. These case studies accumulated information and data of existing structures about their design live loads and acquired detailed drawings showing the reinforcement in their floor slab sections. The actual occupancy loads that act on the floor slabs were assessed, and the ultimate loads that an individual slab section should be able to support were calculated using the methods recommended by ACI, CP-114, CP-110, and the yield line theory. A reinforced concrete slab panel was also tested to check the validity of the theoretically predicted ultimate loads. The results were compared to find a safety margin and, if necessary, recommend lower live load outlines for cost reduction. The case studies showed that there is sufficient margin to reduce design live loads on the floor slabs of residential buildings, especially in multistory apartment blocks. Moreover, it was found that the live loads, especially on residential buildings, could be decreased to two-thirds of the code values without risking floor overloading.

Full textAbstract:
Given the importance of structural analysis, slabs, particularly those made of solid concrete, have several models that allow analyzing them and obtaining the necessary efforts for their dimensioning, among them the grate analogy method. Since this is attractive for this purpose, since it has a simple approach without losing efficiency, this work proposes to study, using this approach, the mechanical behavior, in the linear elastic regime, of solid slabs of a residential floor. Thus, the general objective is to obtain the efforts and displacements of the referred pavement with this technique. For that, a computational code was developed in the Scilab programming language. In order to establish a comparison with other methods, the pavement was also analyzed using Kirchhoff's plate flexion theory and using shell finite elements with the aid of the SAP2000 software. It can be proved, through the study, the efficiency of the analysis of slabs through grid analogy. In addition, the importance of the study is verified considering the floor coupled to the beams, as well as taking into account the cracked state of the concrete, ensuring the achievement of more realistic results, which is important for design purposes.

The results of the study of the technical condition of 14 round-hollow slabs according to the series II-03-02 within the basement of two entrances of a residential building after a fire, lasting about 8 hours. More than 40 years passed from the commissioning of the building to the fire, and all this time the basement slabs were in a non-aggressive environment, but with high relative humidity, which had a positive effect on increasing the concrete strength of typical slabs. Inspection of slabs in adjacent rooms for a long time of operation did not reveal significant defects from their humidification and insufficient thermal insulation properties of the floor above the basement.
 In the inspection area, some floor slabs above the basement were found to be defective due to high temperatures, which reduced their rigidity.
 The information obtained from the survey is necessary to perform verification calculations to determine the load-bearing capacity and stiffness of the floor slabs and compare them with the data from the survey results. The data of test calculations are also needed to substantiate the need for reinforcement work on the slabs, to ensure their further normal operation on the operating loads on the ground floor.
 To analyze the impact on the deflections of slabs of constant and payloads, some of their actions are considered and verified calculations of the deflections of the floor slabs for the four adopted separate stable modes of normal operation.
 A histogram of the change in the actual deflections of the floor slabs above the basement is constructed, according to the analysis of which the area with the largest deflections is clearly traced, which indicates the location of the highest temperatures in this place. That is, the level of vertical deformations of floor slabs can determine the relative temperature distribution within them. Deflections of slabs due to high temperatures should be considered as damage that interferes with normal operation and significantly reduces the durability of slabs.
 Considered after the fire condition of the slabs showed that in the absence of impact on them payloads, the obtained additional temperature deflections are greater than the calculated, which are obtained by verification calculations for the action of full operating loads.
 Also offered different options for strengthening both the slabs themselves and the seams between them, for their joint work on different combinations of loads.

Abstract This paper discusses a case study of a residential building in Benghazi that features slab-on-grade foundations supported by expansive soils. Although such structures are uncommon in the area, they can suffer serious damage due to volumetric changes in the soil caused by wetting and drying. The building has a total plan area of 200 m², with tie beams located 1.2 m above the formation level, and expansive soil used as backfill. After being moistened and lightly compacted, 100 mm thick concrete slabs were poured between the tie beams, resulting in varying slab sizes. Following a month of heavy rainfall, significant cracking—longitudinal, diagonal, and warping—occurred in the slabs due to uneven deformation from the expansive soil. The paper includes photographs of these deformations and cracks, along with an analysis of the geotechnical properties of the expansive soil, including its swelling and shrinking characteristics. It also employs an approach to predict the pressure exerted on the slabs due to differential heave.

Korea has the world's most strict inter-floor noise regulations. In order to build an apartment house with more than 30 units, it must meet the minimum requirement of impact sound level, single number quantities of 49 dB. These regulations make it hard to expand residential tall wood building in Korea. For making quality satisfied CLT floors, as the preliminary investigations, the effects of wood species and CLT panel joints on the vibration and sound insulation performance of CLT were analyzed. The natural frequency range of the CLT slabs is from 20 Hz to 22 Hz. There were no significant differences depending on wood species and CLT panel joint type. As the stiffness of the slabs increased, the floor impact sound insulation performance also improved. The deflection model for CLT slabs was developed and validated with the actual deflection derived by acceleration spectrum. The measured value was 62 ~ 87% of the predicted value.

This research aims to compare Timber concrete slabs (TCC) with solid slabs (RC) to show that TCC may be used to minimize building weight and construction costs. Moreover, the purpose of this project is to use CypeCAD software to design a one-way TCC slab and a two-way solid slab, analyze the data supplied in the software, and compare the findings according to the Eurocode standard. The results illustrate that although the timber concrete composite slab is a new constructive solution and is little used in many constructions, it is less expensive compared to the conventional solution adopted in many countries around the world. This system (TCC Slab) accounts for 62% of the total cost of constructing a solid slab with the same size and architecture. Overall, the TCC slab is cost-effective compared to the solid slab with beams, which can reduce 38% of the total cost of construction. Additionally, the results showed that the TCC slab represents a phenomenal potential to be utilized in residential structures from an economic standpoint, as it is less expensive than a two-way solid slab with a beam (RC slab).

The scientific work is devoted to a comprehensive study of the stress-strain state of prefabricated hollow-core floor slabs, establishing the nature of deformation, as well as determining the characteristics of crack resistance, deformability and load-bearing capacity experimentally under short-term loads. The experimental data obtained were confirmed by theoretical calculations. The scientific novelty of the experiments carried out within the framework of the presented work lies in the improvement of the principles of direct design of floor slabs from commercially produced beam slabs, the possibility of determining the stress-strain behavior of a slab structure using the formed ends. The method of monitoring the stressed behavior of a slab structure was also further developed. For the first time, the results of full-scale experimental studies of the stress-strain behavior of a prefabricated slab, carried out using the hydraulic loading method, have been obtained, and the features of the deformation of a slab embedded in the wall of a multi-story building have been experimentally established. The article provides recommendations for the practical use of the research results obtained, and also develops technical specifications for the production of concrete slabs during design and construction. The developed proposals were used in the construction of residential buildings in Kharkiv. When using the recommended grade of concrete C25/30 (instead of the actual grade C20/25 tested), the rigidity of the slab increases and its deflections will be smaller. Based on the data obtained from the experimental testing of the slabs, a generally positive test result should be stated. During further serial production of slabs, periodic testing of batches of slabs should be carried out in accordance with DSTU B V.2.6-53:2008. In this case, the slabs are accepted according to the indicators of strength, rigidity, crack resistance, fire resistance limits, frost resistance limits, as well as water resistance of slabs intended for use in aggressive environments. Keywords: concentrated load, testing, concrete, calculation, deflection, transverse force.

There are no clear design standards for the reinforcements or concealed beams under partitions in reinforced concrete slabs which often appear in reinforced-concrete residential buildings. Designers, in most cases, have to rely on engineering experiences after a simple calculation to design such reinforcements or concealed beams. In this paper, we built a finite element model of such reinforced concrete slabs in SAP2000. The element for the plates was layered shell element. By changing the span , thickness and boundary constraints of the plate, the materials of the partition , the diameter of the reinforcements to analyze the force of the plate. Based on results analyzed, we discuss the internal forces of such plates, and offer suggestions for the selection of partitions and design of reinforcements.

This article presents the visual and instrumental investigations, along with the necessary engineering and technical decisions, for restoring load-bearing structures of multi-storey residential buildings damaged by fire due to war. It is economically advisable to replace and strengthen 20% of the emergency floor slabs and 16% of the load-bearing walls to allow residents to return to their homes as soon as possible. The temperature during the fire was determined using specific samples of damaged materials, building structures, and equipment, which allowed for a more accurate assessment of the damage to brick walls and prefabricated reinforced concrete floor slabs. The possibility of further use of the building was also determined based on a survey and necessary measurements of its structures, including the determination of physical and mechanical characteristics (crack width, flexures, concrete strength, brick grade, and mortar grade). The prefabricated reinforced concrete round hollow floor slabs had delaminated along the ribs between the hollows, showing sagging. The bricks had changed colour and were destroyed to a depth of 120 mm (internal walls were destroyed to this depth on both sides). Considering the extent of the damage to the load-bearing structures, it is recommended that the inter-floor ceilings, load-bearing walls, and partitions be replaced and strengthened. For structures that do not require replacement or reinforcement, the justification for their continued safe operation has been completed in accordance with the construction standards and regulations in force in Ukraine.

Full textAbstract:
Precast concrete (PC) slabs are widely used in the assembly of concrete residential buildings. The PC slabs are manufactured at the factory and then arranged in stacks for transport to the construction site for assembly. Currently, optimization of the stacking plans for PC slabs focuses on yard-space utilization and transportation efficiency and rarely considers the assembly sequence; secondary sequencing of prefabricated elements is required during construction to meet the lifting scheme, which leads to increased construction preparation time and risk of worker injury. To enable stacking crews to generate stacking plans rapidly and systematically to improve the on-site lifting efficiency of the components, this paper proposes a storage-location allocation model with two objectives: reduce secondary-sorting workload and increase stacking stability for PC slabs. At the same time, it must match the characteristics of the problem. To prevent the solution from falling into the local optimum during the evolution of the particle swarm optimization algorithm, we introduce an elitist learning strategy, which can improve the solutions when the group converges. Finally, we verify our allocation model and optimization algorithm through example simulations. The simulation results show that, compared with the traditional method, the stacking plans generated by this method have a lower secondary-sorting workload and higher stacking stability when using the same number of storage racks.

Abstract The regular slab is often supported by a beam in modern construction, With a modest slab width and a big beam deep, the weight is transmitted from beam to column. Because of the flat slab, architects may construct partition walls wherever they are required. It is popular since it assists with weight reduction, stimulates quick development, and is did-not expensive. Similarly, since its debut, the classic slab has brought benefits such as greater rigidity. It offers a higher weight bearing capacity while also being good and economical. Grid slabs are required if the span is higher than one span, while grid beams are given if the span is less than one span. Grid slabs are good for longer spans with large loads because they eliminate voids that would otherwise result in dead load. Some slabs are less costly and more resistant to vibration. The study’s purpose is to determine which of the three slab varieties, regular slab, flat slab with drop, and grid slab, is the most benefits. a G+5 This study looked at storey displacement, shear force, bending moment, and storey drift in a residential multi-story structure with different slab.

Article considers the case of optimizing design solution for foundation of a 10-storey residential building on sandy soils. Optimization was achieved through experimental work with 2*2*0,2 m reinforced concrete slabs and 5000 cm2 stamps. During slabs testing slab settlements, in concrete and reinforcement, as well as contact pressure under slab were measured. During stamps testing displacements of the stamp and surrounding soil were measured at 21 points. As a result of the tests deflection slab mode, slab-soil contact stresses, changes in radius of curvature, relative deformation of concrete and reinforcement in upper and lower parts of the slab during loading were obtained. Results of experimental data made it possible to select a foundation model, which was later used for foundation design. Recommendations are given for determining soil deformation characteristics, modeling soil-plate interaction, as well as economic efficiency of foundation design solution.

This paper presents the bending characteristics of sawdust-crete laminated composite slab. The materials used in the laboratory experiments include: Ordinary Portland Cement, river sand, gravel, sawdust, plywood, nails, reinforcement bars, stirrups and water. Manual mixing method was adopted and all sawdust-crete ingredients were batched by weight. A total of 48 slabs of size 1200mm x 1000mm x 100mm, 1200mm x 1000mm x 125mm, 1200mm x 1000mm x 150mm and 1200mm x 100mm x 175mm were cast for flexural strength from the mix ratios 0.75:1:2:2 and 0.75:1:3:3. Out of the 48 slabs cast, 32 were produced from sawdust-crete laminated composite (with 12.5mm and 20mm as the thickness of plywood for the laminate), 8 were produced from normal concrete ingredients (coarse aggregates, fine aggregates, cement and water) with 10mm rebar and mix ratio of 0.45:1:2:4. The remaining 8 slabs were made from plain sawdust-crete with mix ratio of 0.75:1:3:3. During the experiment, the maximum deflection for the slab was observed to occur at the slab with size 1200mm x 1000mm x 100mm no matter the core content used to produce the slab while the minimum deflection occurs at the size 1200mm x 1000mm x 175mm. The deflection of slab decreases with increase in slab thickness while flexural strength increases with increase in slab thickness. The flexural strength results of slab were compared by percentage difference and the results shows that there is significant difference between the two sets of slabs. Also, by comparing the results of plain sawdust-crete slab to that of sawdust-crete laminated composite slab, the result show that laminates with plywood increases flexural strength up to 68.4%. Conclusively, laminated sawdust-crete can be used for slabs that is not carrying too much load like residential houses.

The reinforced concrete slabs were designed under static load according to ACI-318R-2014 and then the adequacy was checked under harmonic dynamic loading. The static loading consists of dead load and residential live load considering according to ASCE-07-2010. Modeling analysis was performed to determine the eigenvalues and eigenvectors values and then frequency response analyses of the slab by finite elements method that adopted for analysis. The results indicated that in case of self-compacted reactive powder concrete rather than normal concrete gave deflection less and also there was a different result of deflection according the type of slab boundary condition supports.

This study aims to identify waterproofing materials and methods for specific underground structure components through experimental evaluations and to assign waterproofing performance ratings similar to existing apartment house grades. These performance ratings will serve as foundational data to prevent leakage in joint residential complexes. This study proposes composite and self-adhesive sheet waterproofing as effective methods, emphasizing the significance of sheet waterproofing materials for excellent performance. The need for improved waterproofing materials to address long-term permeability issues is also highlighted. This research provides essential data for future waterproofing performance ratings; therefore, contributing to construction quality and safety in joint residential complexes.

The experience of many years of operation of large-panel buildings in various regions of our country has revealed a number of significant problems. They are connected both directly with the very design features of the buildings of the first industrial period, and with the quality of their manufacture, namely, deviations from the design solutions of structural elements in the manufacturing process. They did not affect the overall safe operation of buildings, but they did affect the performance of these structures. These include floor slabs for residential large-panel buildings, supported on two sides by a beam scheme, which, during the manufacturing process, received a deviation in the thickness of the protective layer of reinforcement from the design values in the direction of increase. This, in turn, during operation led to an increase in the deflection of floor slabs, in some cases more than the normative ones. Modern research has revealed the effectiveness of the use of alternative solutions - three-layer floor structures, which provide increased performance characteristics of panel buildings.

Full textAbstract:
A common practice in the construction of residential and commercial buildings in Saudi Arabia is to insulate the outer walls and windows only. Other building components such as the roof, columns and slabs, and doors are usually neglected. Moreover, vital components such as the roof and windows are especially neglected in commercially built residential and commercial buildings. The aim of this study is to put this common impression and practice to the test by quantifying the contribution of every building component to the overall air-conditioning load of the building. The hypothesis evaluated in this paper is that despite the common practices, there could be an optimum selection of insulators for the building components that yields the lowest energy consumption and maximum savings not only in energy costs but also installation costs. The required air-conditioning load is determined using manual calculations and the HAP software package for 1022 possible configurations. The findings of the analysis point to the importance of the roof, as it is the major contributor to the thermal load, followed closely by columns and slabs, with 44.2% of the overall cooling load. It is found that a single wall consisting of 2 cm of cement plaster, 20 cm of cement–polyurethane brick, and 2 cm of cement plaster is less expensive and has higher thermal resistance than any of the more expensive double walls. The study found one scenario of possible configurations with the optimized selection of building materials and their insulation materials that provides the most effective insulation at the lowest cost.

As building codes are pushing towards higher energy efficiency and the arrival of nearly Zero Energy Building (nZEB) requirements for all new buildings are just around the corner the need for alternative, high efficiency heating and cooling solutions for nZEB’s is greater than ever. Also as experience with renewable energy sources has proven the energy demand and energy generation rarely overlaps and it does not allow to fully utilise some renewable energy sources. This is a simulation study that focuses on integrated cooling and energy storage system utilising phase-change materials (PCM). Several types of thermally activated slabs with different PCM thicknesses were simulated in order to find the most optimal PCM thickness with melting point temperature that can support passive cooling methods based on adiabatic cooling principles. Two calculation tools were used for the study – IDA ICE 4.8 and U-NORM 2012-2 to calculate the properties of the slabs and potential of application in well insulated residential building in Baltic climate. The results showed that the optimal thickness for thermally activated PCM layer (large flat containers) range from 25 mm to 90 mm, and for layers with no thermal activation – 180 mm and more. Moreover the results show that apart from energy storage the thermally activated panel can increase thermal comfort conditions.

A residential building, a brick/concrete structure built up in 1990s was used for many years. Since a deep foundation pit construction was being done in the north, the residents were worrying about the cracks in the building and its safety. Therefore, the following works were done such as the spot checks of the building engineering quality were done; the test and analysis were carried out over the cracks development after the foundation pit was backfilled, the influence assessment of the foundation construction under the mutual effects of pilings and anchor rods over the residential building structure was also conducted; finally the recheck calculation and safety evaluation were made over the building structure. The result shows that the foundation digging leads to new cracks on the nearby residential building but does not endanger its structural safety; after the foundation was backfilled, the hidden danger on the building’s northern side slop was eliminated and the structure cracks tend to be stable; the complete engineering structure is safe and in conformity with the requirements of safety and anti-vibration during the construction period, however, the multiple-pore slabs’ piecing affects the structural integrity and vibration proof performance.
