Plastic Hinges

The plastic hinge is a key concept of the theory of frames that differentiates this theory from the remaining models for structural analysis. This chapter is exclusively dedicated to define this concept and describe the different models of plastic hinges. It also discusses the differences of implementation between plastic hinges in steel frames (Sections 6.1-6.4) and those in reinforced concrete structures (Sections 6.5-6.6). This chapter is based on the ideas presented in Chapter 5 and it allows formulating the models for elasto-plastic frames that are introduced in the next chapter.

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.

<p><strong>Abstract.</strong> Presentation consists of three parts, which are interconnected:</p><ol><li>BIM application for plants treatment and other complicated structures in the field of water management</li><li>Statics of water management structures in the BIM environment</li><li>Application of Common Data Environment (CDE) for water management</li></ol><p>Two areas – statics and water management technology – are crucial for water management structures. Speaking of statics, we mean the statics of reinforced concrete structures. In our company AQUA PROCON s.r.o. we deal with this area comprehensively, ie. from the initial design in the BIM architectural and construction software, through transferring a load-bearing model to BIM software for 3D reinforcement modelling to evaluating model in static design software. All communication is held in Common Data Environment (CDE). Within this environment, a three-way communication is carried out by the designer, contractor and contracting authority. Part of our performance is also above-standard support for reinforced concrete contractors. We provide models of reinforced concrete structures in LOD 400. The use of Common Data Environment (CDE) does not concern only statics, but also the work of all other professions and project participants. Our activities and workflows are based on the philosophy of OPENBIM and IFC.</p>

Strength Criteria

Themodern stage of modelling of behavior of reinforced concrete structures is associated with the widespread use of numerical methods. Thedistinctive paper is devoted todevelopment and numerical implementation of methods of structural analysis including progressive collapse analysis of spatial plate-shell reinforced concrete structures with allowance for physical nonlinearity, crack formation and inducedanisotropy. The relevance of the research topic is substantiated, the current status of research on this topic in Russia and abroad (including various aspects dealing with types of diagrams for modelling of reinforced concrete structures,construction of general deformation models of reinforced concrete, strength criteria for reinforced concrete structures and methods of structural analysis) is analyzed, the goals, objectives and boundaries of the study are determined, the provisions constituting scientific novelty, theoretical significance and practical significance are formulated, publications on the topic are under consideration. It should be noted that generallyfurther improvement and modifications of reinforced concrete models and their integration incontemporarysoftware systems for structural analysis remain very important. It is assumed that developing methods of analysis of reinforced concrete structures will replace multi-iterative approaches to the solution of physically nonlinear problems and move from the practically possible high-precision analysis of individual structures to the analysis of complex structural systems with allowance for various factors of physical nonlinearity and anisotropy. As a result,reliability of design solutions will increase significantly. The strength criteria used in this way, in turn, will also eliminate a number of errors in existing methods for strength analysis.

Abstract Conventional structural analysis of buildings in reinforced concrete is performed considering beam-column connections as rigid. However, experimental results prove the existence of relative rotations in beam-column connections of reinforced concrete structures, showing the partial transfer of bending moment. In this study the influence of the stiffness of beam-column connections on the global stability and in the column bending moments of buildings in reinforced concrete was investigated. A building was designed with rigid connections and deformable connections to identify the importance of considering the influence of the stiffness of the beam-column connections in the overall stability of monolithic and in the redistribution efforts in reinforced concrete structures. In order to determine the stiffness rotation of deformable connections, two analytical models available in literature were used, and a comparison between the results obtained by each analytical model was also performed. Based on the results, it is concluded that neglecting the influence of the stiffness of the beam-column connections on the analysis of monolithic reinforced concrete structures may result in different solutions compared to the real behavior of the structure. The stiffness values obtained with the analytical models usually differ from the condition of rigid connections, suggesting an adjustment on the standard consideration of rigid connections adopted by the computer programs of structural calculation.
