Abstract:
In the concrete dam construction, it is very necessary to strengthen the real-time monitoring and scientific management of concrete temperature control. This paper constructs the analysis and inverse analysis system of temperature stress simulation, which is based on various useful data collected in real time in the process of concrete construction. The system can produce automatically data file of temperature and stress calculation and then achieve the remote real-time simulation calculation of temperature stress by using high performance computing techniques, so the inverse analysis can be carried out based on a basis of monitoring data in the database; it fulfills the automatic feedback calculation according to the error requirement and generates the corresponding curve and chart after the automatic processing and analysis of corresponding results. The system realizes the automation and intellectualization of complex data analysis and preparation work in simulation process and complex data adjustment in the inverse analysis process, which can facilitate the real-time tracking simulation and feedback analysis of concrete temperature stress in construction process and enable you to discover problems timely, take measures timely, and adjust construction scheme and can well instruct you how to ensure project quality.

Abstract:
The currently existing deterministic models for determination of structure service life do not take into account to the full extent variety of factors that have an effect on them and also stochastic characteristics of the used natural materials and conditions for manufacturing construction products, possible errors during the process of designing and construction etc. More trustworthy approach determining longevity and growth rate of destruction processes for structures in future periods can be obtained with the help of statistic methods that take into account a probabilistic essence of the process. The paper presents a possible approach of the probabilistic analysis on reinforced concrete structure service life while assessing rates of variation in depth growth of carbonization in a concrete protective layer on the basis of the existing experimental and calculated data pertaining to changes of the given index in reinforced concrete structures of various types. Variability of the existing approaches for determination of structure longevity as a whole has been shown firstly due to various number of basic vаriables used in calculations. Stochastic processing of the data on parameters of carbonization depth in the concrete protective layer has been carried out and this processing has made it possible to determine variation rates which allow to assess the presupposed service life of reinforced concrete structures having similar characteristics and being operated under analogous conditions. A definitive non-uniformity in statistic indices has been established that testifies about the necessity to increase accumulation of data on the investigated characteristics and to execute its processing more thoroughly. An expedience in usage of a concrete impermeability as a main factor determining its longevity has been established on the basis of statistical assessment of the existing data.

Abstract. An analysis of modern capital construction state shows that the material and technical base of the construction industry does not allow the production of effective building materials and products in the required quantity without due consideration of the economic burden on the environment, and now significant financial costs are required to restore the ecological balance of the natural zone. Power plant fly ash is a man-made raw material for many industries, which is utilized up to 92% in dry form and is of practical interest in the production of effective thermal insulation building materials and products as a filler and an aggregate. In view of the instability of the chemical and mineralogical composition, the content of raw fuel, as well as the pozzolanic activity, the study of the profitability of the production of pozzolanic cements and concretes based on them was carried out, with an increase in sulfate resistance, corrosion resistance of the aggregate while preventing thermal cracking. The expediency of autoclaved gas-ash-slag concretes production with the use of cement with high content of highly basic minerals ‒ alite and tricalcium aluminate is proved. The technology of obtaining ash-alkaline cellular concrete using ash-removal and alkaline component is given. The economic efficiency of cellular ash-containing concretes is justified by the replacement of sand with ash, a 1.2-1.5-fold reduction in lime consumption compared to lime-sand concrete and a reduction of approximately 2 times the capital costs for extraction and processing of raw materials. Comparative physical and mechanical parameters of autoclave and non-autoclave aerated concrete products are given. The process of manufacturing products by vibro-vacuuming and vibratory compaction of ash concrete is presented. The strength data of vacuum concrete are given, which are 30-40% higher than that of vibro- compacted concrete from a rigid mixture. The investigated value of shrinkage as a result of the water-reducing effect of ash, provides a decrease in the water-cement ratio of concrete. Autoclaved and non-autoclaved aerated concrete can compete with such an effective thermal insulation material as mineral wool. They are more effective materials for low-rise and frame housing construction than traditional brick and concrete.

Abstract:
In this paper, Big Data is considered as an "umbrella" term that combines various concepts, technologies and methods of data processing in distributed information systems that provide a qualitatively new useful information (new knowledge). The stages of "standard" research in the Big Data approach are described. A brief description of the Big Data ecosystem, which consists of several main categories, is given. Various projects and initiatives at the national and international levels are considered, as well as examples of the use of Big Data in business, economy, and society. As concrete examples of the construction and use of analytical platforms for Big Data, successful socio-economic research carried out by the authors as part of research teams at the Plekhanov Russian University of Economics is presented. The Big data metaphor is certainly successful, since it naturally connects a complex of concepts, technologies and methods of Big data with the economy by hinting at a connection with other well-known metaphors –"Big oil", "Big ore", etc.

Abstract:
A fully automated computer program is developed for the optimum design of steel space trusses acting compositely with a concrete slab placed on top. The program sizes the truss members to meet the requirements of the load and resistance factor design specification of the American Institute of Steel Construction using the load combinations of ANSI. Earthquake loading is not considered. The optimum size is based on minimum cost, regarding the amount of welding required at the joints and of the member itself. The total cost is based on all steel work in the truss. Once the truss configuration has been defined, and it has been ensured that linear elastic behavior exists, the structure is analyzed for the construction process, to make sure that no overstressing will take place in any structural element at any time during construction and service. The analysis and design principles are presented and an actual design case is solved. (Abstract shortened with permission of author.)

Abstract:
In this thesis, several aspects of GPR data processing for RC bridge decks are studied. First, autofocusing techniques are proposed to replace the previous expensive and unreliable human visual inspections during the iterative migration process for the estimation of the velocity/dielectric permittivity distribution from GPR data. Second, F-K filtering with dip relaxation is proposed for interference removal that is important for both imaging and the performance of post-processing techniques including autofocusing techniques and CS-based migration studied in this thesis. The targeted interferes here are direct waves and cross rebar reflections. The introduced dip relaxation is for accommodating surface roughness and medium inhomogeneity. Third, the newly developed CS-based migration is modified and evaluated on GPR data from RC bridge decks. A more accurate model by accounting for impulse waveform distortion that leads to less modeling errors is proposed. The impact of the selection of the regularization parameter on the comparative amplitude reservation and the imaging performance is also investigated, and an approach to preserve the comparative amplitude information while still maintaining a clear image is proposed. Moreover, the potential of initially sampling the time-spatial data with uniform sampling rates lower than that required by traditional migration methods is evaluated.

Abstract:
Bibliography: pages 128-132.<br>A micro-computer based package for the analysis and design of prestressed flat slabs is presented. The constant strain triangle and the discreet Kirchhoff plate bending triangle are combined to provide an efficient "shell" element. These triangles are used for the finite element analysis of prestressed flat slabs. An efficient out-of-core solver for sets of linear simultaneous equations is presented. This solver was developed especially for micro-computers. Subroutines for the design of prestressed flat slabs include the principal stresses in the top and bottom fibres of the plate, Wood/Armer moments and untensioned steel areas calculated according to Clark's recommendations. Extensive pre- and post-processing facilities are presented. Several plotting routines were developed to aid the user in his understanding of the behaviour of the structure under load and prestressing.

Abstract:
The aim of this research is to improve the efficiency of the construction process through the application of electronic data interchange (EDI). This thesis describes the development and application of EDI messages. The messages described are targeted to provide a means for transferring construction specific information during the construction process. The definition of electronic data interchange and its technical issues are first described. The nature of EDI, replacing paper based communication with electronic messages, impacts on the way in which business is conducted, and also has far reaching legal implications due to the reliance of many legal systems on paper documents and signatures. The business and legal implications are therefore discussed in detail. The application of EDI in the construction industry is investigated by means of a literature review. This work is furthered by a longitudinal study of the construction industry's application of EDI, which consisted of two surveys at a five year interval. A model of the information flows within the traditional construction process is developed to assist in the identification of information flows suitable for EDI. A methodology for message development was produced. The methodology was then applied to develop a description data model that could be utilised in the existing bill of quantity and trading cycle messages. The bill of quantity message set was at a stage ready for trial. To determine the issues related to implementation specifically in the construction industry a trial implementation of this message set was undertaken. The official implementation undertaken by EDICON is described. Software was also developed to undertake the trial. This software was tested and proved the message set developed was suitable for the transfer of bill of quantity related information during a construction project. The factors causing the failure of the implementation of the bill of quantities message set are discussed. A number of these factors are considered valid for all construction project information flows. Finally, the use of shared project models to re-engineer construction information tasks is recommended as a means of achieving significant benefit from electronic data exchange in the construction process.

Abstract:
In July 2004, Electric Boat Corporation decided to retrofit Graving Dock 3 at its Groton, Connecticut shipyard with a reinforced concrete wall designed and constructed to replace the existing cellular cofferdams that comprise the dock. Since the cofferdams are of various heights and have deflected in different ways over the years, an efficient method was needed to capture the as-built configuration of the graving dock before design of the wall could be finalized. The owner, design agent and contractor chose a combination of 3D laser scanning, post processing, and CAD modeling to capture this as-built condition. The resulting three dimensional CAD surface model of the dock became integral with the design of the wall and its construction. This paper will provide an overview of the reasons laser scanning was chosen and a description of how the laser scans were taken and processed. The paper will also discuss how a CAD model was created from the processed data, and more significantly, how the model was used in the development of design and construction drawings. The paper will conclude with a look at how 3D laser scanning is being used on other projects at Electric Boat, for both shipbuilding and facilities.

Abstract:
Строительно-технические свойства бетонов, используемых для замоноличивания стыков конструкций, имеют важное значение. С увеличением водоцементного отношения расширение бетонных образцов во время обогрева возрастает по величине и уменьшается по продолжительности своего развития. Обогрев в условиях частично-исключенной массоотдачи интенсифицирует расширение и рост прочности, а тепловые процессы закрепляютрасширяющуюся структуру. К бетону заделки стыков конструкций предъявляются определенные требования по плотности, так как бетон заделки несет также функции антикоррозийной защиты. Предварительное выдерживание напрягающего бетона в нормальных условиях до его термообработки позволяет набрать необходимую прочность. Выполненные опыты показали, что сцепление арматуры с напрягающим бетоном несколько выше чем с обычным бетоном. С увеличением водоцементного отношения и температуры изотермического выдерживания величина сцепления арматуры с бетоном после его термообработки снижается. Замоноличивание стыков предусматривает использование литых бетонных смесей, что дает возможность применения суперпластификаторов. Их присутствие снижает электрическое сопротивление бетонной смеси и увеличивает водоудаление. Важной является проблема морозо и водостойкости бетонов стыков, связанная с обеспечением его долговечности. Результаты проведенных исследований показали достаточную морозостойкость и водонепроницаемость напрягающего бетона для обеспечения эксплуатации замоноличенных стыков конструкций. The construction and technical properties of concrete used for monolithic joints of structures are important. With an increase in the water-cement ratio, the expansion of concrete samples during heating increases in magnitude and decreases in duration of its development. Heating under conditions of partially-excluded mass transfer intensifies the expansion and growth of strength, and thermal processes fix the expanding structure. Concrete sealing joints of structures are subject to certain density requirements, since concrete sealing also carries the functions of corrosion protection. Preliminary exposure of tensile concrete under normal conditions to its heat treatment allows you to gain the necessary strength. The performed experiments showed that the adhesion of reinforcement with tensile concrete is not much higher than with ordinary concrete. With an increase in the water-cement ratio and the temperature of isothermal aging, the adhesion of the reinforcement to concrete after its heat treatment decreases. The monolithization of joints involves the use of cast concrete mixtures, which makes it possible to use superplasticizers. Their presence reduces the electrical resistance of the concrete mix and increases water removal. An important problem is the frost and water resistance of concrete joints, associated with ensuring its durability. The results of the studies showed sufficient frost resistance and water tightness of the straining concrete to ensure the operation of monolithic joints of structures.

Abstract:
This report summarizes activities undertaken to support and ensure that the Illinois Department of Transportation utilizes the best demonstrated available technology for design and construction of full-depth hot-mix asphalt (HMA) pavements and HMA pavements on rubblized Portland cement concrete pavement (PCCP). To achieve this goal, the researchers reviewed pavement design and special provisions for full-depth asphalt and rubblization projects as well as full-depth asphalt and rubblization project performance via condition surveys and deflection measurements. They also modified design inputs as needed from the review of literature and responded to specific issues related to full-depth asphalt and rubblization design and construction. The researchers studied 32 rubblization projects on the interstate system and found this rehabilitation technique is providing good to excellent performance that exceeds design expectations. They provided input on proposed changes to full-depth hot-mix asphalt pavement on rubblized PCCP specifications as well as provided input on the RoadTec 1105e material transfer device. Analysis of traffic speed deflectometer data obtained on several hot-mix asphalt and rubblized pavements resulted in the development of analysis algorithms.

Abstract:
The Sagamore Parkway Bridge consists of twin parallel bridges over the Wabash River in Lafayette, IN. The old steel-truss eastbound bridge was demolished in November 2016 and replaced by a new seven-span concrete bridge. The new bridge consists of two end-bents (bent 1 and bent 8) and six interior piers (pier 2 to pier 7) that are founded on closed-ended and open-ended driven pipe piles, respectively. During bridge construction, one of the bridge piers (pier 7) and its foundation elements were selected for instrumentation for monitoring the long-term response of the bridge to dead and live loads. The main goals of the project were (1) to compare the design bridge loads (dead and live loads) with the actual measured loads and (2) to study the transfer of the superstructure loads to the foundation and the load distribution among the piles in the group. This report presents in detail the site investigation data, the instrumentation schemes used for load and settlement measurements, and the response of the bridge pier and its foundation to dead and live loads at different stages during and after bridge construction. The measurement results include the load-settlement curves of the bridge pier and the piles supporting it, the load transferred from the bridge pier to its foundation, the bearing capacity of the pile cap, the load eccentricity, and the distribution of loads within the pier’s cross section and among the individual piles in the group. The measured dead and live loads are compared with those estimated in bridge design.

Abstract:
Recent advances in visual sensing technology have gained much attention in the field of bridge inspection and management. Coupled with advanced robotic systems, state-of-the-art visual sensors can be used to obtain accurate documentation of bridges without the need for any special equipment or traffic closure. The captured visual sensor data can be post-processed to gather meaningful information for the bridge structures and hence to support bridge inspection and management. However, state-of-the-practice data postprocessing approaches require substantial manual operations, which can be time-consuming and expensive. The main objective of this study is to develop methods and algorithms to automate the post-processing of the visual sensor data towards the extraction of three main categories of information: 1) object information such as object identity, shapes, and spatial relationships - a novel heuristic-based method is proposed to automate the detection and recognition of main structural elements of steel girder bridges in both terrestrial and unmanned aerial vehicle (UAV)-based laser scanning data. Domain knowledge on the geometric and topological constraints of the structural elements is modeled and utilized as heuristics to guide the search as well as to reject erroneous detection results. 2) structural damage information, such as damage locations and quantities - to support the assessment of damage associated with small deformations, an advanced crack assessment method is proposed to enable automated detection and quantification of concrete cracks in critical structural elements based on UAV-based visual sensor data. In terms of damage associated with large deformations, based on the surface normal-based method proposed in Guldur et al. (2014), a new algorithm is developed to enhance the robustness of damage assessment for structural elements with curved surfaces. 3) three-dimensional volumetric models - the object information extracted from the laser scanning data is exploited to create a complete geometric representation for each structural element. In addition, mesh generation algorithms are developed to automatically convert the geometric representations into conformal all-hexahedron finite element meshes, which can be finally assembled to create a finite element model of the entire bridge. To validate the effectiveness of the developed methods and algorithms, several field data collections have been conducted to collect both the visual sensor data and the physical measurements from experimental specimens and in-service bridges. The data were collected using both terrestrial laser scanners combined with images, and laser scanners and cameras mounted to unmanned aerial vehicles.
