Computational Methods for Reinforced Concrete Structures

The book covers the application of numerical methods to reinforced concrete structures, To analyze reinforced concrete structures linear elastic theories are inadequate because of cracking, bond and the nonlinear and time dependent behavior of both concrete and reinforcement, These effects have to be considered for a realistic assessment of the behavior of reinforced concrete structures with respect to ultimate limit states and serviceability limit states, The book gives a compact review of finite element and other numerical methods, The key to these methods is through a proper description of material behavior, Thus, the book summarizes the essential material properties of concrete and reinforcement and their interaction through bond, These basics are applied to different structural types such as bars, beams, strut and tie models, plates, slabs and shells, This includes prestressing of structures, cracking, nonlinear stressstrain relations, creeping, shrinkage and temperature changes, Appropriate methods are developed for each structural type, Large displacement and dynamic problems are treated as well as short-term quasi-static problems and long-term transient problems like creep and shrinkage, Most problems are illustrated by examples which are solved by the program package ConFem, based on the freely available Python programming language, The ConFem source code together with the problem data is available under open source rules at concrete-fem,com, The author aims to demonstrate the potential and the limitations of numerical methods for simulation of reinforced concrete structures, addressing students, teachers, researchers and designing and checking engineers, Ulrich Haussler-Combe, Prof, Dr,-Ing, habil, studied structural engineering at the Technical University Dortmund and gained his doctorate from the Karlsruhe Institute of Technology (KIT), Following ten years of construction engineering and development in computational engineering, he came back to KIT as a lecturer for computer aided design and structural dynamics, Since 2003 he has been professor of special concrete structures at Dresden University of Technology,
