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 stress-strain relations, creeping,
shrinkage and temperature changes.
Appropriate methods are developed for each structural type. 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 in combination
with this book.
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.
