Reinforcement Bar

Structural building information modeling (S-BIM) for reinforced concrete walls based on parametric technique has studied. There are structural analysis and design packages for reinforced concrete structures. 3D BIM platforms which are recently developed and widely adopted in the construction industry are mostly experiencing a difficulty in interoperability with structural analysis and design packages. The modeling of reinforcement placement in the reinforced concrete structures can not be performed using current BIM platforms based on the result of structural analysis and design. This study develops the algorithm and implementation of integrated reinforcement bar placement system by creating a database that stores the results of structural analysis and design so that overall reinforced concrete model including re-bar can be built. Utilization of S-BIM can reduce the time of engineering, the production of working drawing and shop drawing.

The construction industry is facing the Building Information Modeling (BIM) paradigm and all its potential. In order to this paradigm becomes largely adopted and fully utilized, the interoperability issue must be properly addressed. While the IFC schema covers the data model necessary for data exchange, the processes occurring daily in the industry need to be better known. In this sense, this paper reports a research that explored the design process of reinforced concrete structures using BIM based systems. To reach this goal, a case study was developed in a structural design company, where the researcher collected data by participant observation, interviews and documental analysis. After the data collection and the analysis of the internal design routines and external communications during the design process, process maps were elaborated containing all the activities developed during the contracted projects. Furthermore, it was appropriately registered the information requirements for each one of the activities using the IDM (Information Delivery Manual) standards. It was possible to characterize the design process of reinforced concrete structures in the studied company when using BIM based systems, as well as to identify the stakeholder information requirements. After the processes and information flows analysis it was also possible to propose a new optimized workflow. This workflow aimed to reduce the number of analogic activities during the studied design process, as well as helped to propose new information exchanges following the IDM methodology.

Purpose Additive manufacturing (AM) and building information modelling (BIM) are emerging trends for which it has been claimed that both increase both efficiency and productivity in the construction industry. This study aims to synthesise and aggregate the literature addressing BIM integration in the AM of concrete structures and to exploit the joint value creation potential. Design/methodology/approach This study firstly applies a mixed-review method to achieve mutual corroboration and interdependency between quantitative and qualitative research approaches. Bibliometric mapping is applied to identify, map and synthesise the relevant literature. Scoping review is used to examine the extent, gap, range and nature of the research activity. Afterward, a cross-situational analysis, the threats, opportunities, weaknesses and strengths2 matrix, is proposed and applied to exploit the joint value creation potential of different aspects of AM and BIM. Findings The study reveals a substantial interest in this field. However, progress in terms of integration is slow compared to the rapid development in interest in the two trends individually. The literature discusses or conceptualises such integration at building-scale, while prototyping or proof-of-concept processes are only rarely used. The study identified 12 joint value creation potentials through the integration of BIM in AM for concrete structures, which can create value by enabling more optimised designs, automated construction processes and data analytics that can apply throughout the building life-cycle process. Originality/value The advancements of BIM integration in the AM of concrete structures are analysed and joint value creation potentials are proposed. The study proposes a cross-situation analysis that can be applied to structure joint value creation potentials from the multi-dimensional integration of different factors and topics, especially for emerging technologies.

Precast Elements

Currently, prefabricated reinforced concrete structures are widely used for the construction of buildings of various functional purposes. In this regard, has been developed SP 356.1325800.2017 "Frame Reinforced Concrete Prefabricated Structures of Multi-Storey Buildings. Design Rules", which establishes requirements for the calculation and design of precast reinforced concrete structures of frame buildings of heavy, fine-grained and lightweight structural concrete for buildings with a height of not more than 75 m. The structure of the set of rules consists of eight sections and one annex. The document reviewed covers the design of multi-story framed beam structural systems, the elements of which are connected in a spatial system with rigid (partially compliant) or hinged joints and concreting of the joints between the surfaces of the abutting precast elements. The classification of structural schemes of building frames, which according to the method of accommodation of horizontal loads are divided into bracing, rigid frame bracing and framework, is presented. The list of structural elements, such as foundations, columns, crossbars, ribbed and hollow floor slabs and coatings, stiffness elements and external enclosing structures is given; detailed instructions for their design are provided. The scope of the developed set of rules includes all natural and climatic zones of the Russian Federation, except seismic areas with 7 or more points, as well as permafrost zones.

Deformation Diagrams

Problems when calculating reinforced concrete structures based on the concrete deformation under compression diagram, which is presented both in Russian and foreign regulatory documents on the design of concrete and reinforced concrete structures are considered. The correctness of their compliance for all classes of concrete remains very approximate, especially a significant difference occurs when using Euronorm due to the different shape and sizes of the samples. At present, there are no methodical recommendations for determining the ultimate relative deformations of concrete under axial compression and the construction of curvilinear deformation diagrams, which leads to limited experimental data and, as a result, does not make it possible to enter more detailed ultimate strain values into domestic standards. The results of experimental studies to determine the ultimate relative deformations of concrete under compression for different classes of concrete, which allowed to make analytical dependences for the evaluation of the ultimate relative deformations and description of curvilinear deformation diagrams, are presented. The article discusses various options for using the deformation model to assess the stress-strain state of the structure, it is concluded that it is necessary to use not only the finite values of the ultimate deformations, but also their intermediate values. This requires reliable diagrams "s–e” for all classes of concrete. The difficulties of measuring deformations in concrete subjected to peak load, corresponding to the prismatic strength, as well as main cracks that appeared under conditions of long-term step loading are highlighted. Variants of more accurate measurements are proposed. Development and implementation of the new standard GOST "Concretes. Methods for determination of complete diagrams" on the basis of the developed method for obtaining complete diagrams of concrete deformation under compression for the evaluation of ultimate deformability of concrete under compression are necessary.
