01/12/2001  Nonlinear finite element analysis was applied to various types of reinforced concrete structures using a new set of constitutive models established in the fixed-angle softened-truss model (FA-STM). A computer code FEAPRC was developed specifically for application to reinforced concrete structures by modifying the general-purpose program FEAP. FEAPRC can take care of the four

Further, it is discussed how the finite element method may be applied effectively in the analysis of different types of reinforced concrete structures. In particular, it is explained that special precaution must be exercised in order to develop efficient and reliable solution algorithms for the nonlinear equations. Several computational examples are presented involving nonlinear collapse or ...

This paper deals with three-dimensional nonlinear finite element analysis of concrete structures. A new three-parameter failure criterion, formulated in terms of three stress invariants, is suggested for plain concrete. The criterion can accurately describe available experimental data throughout the stress range from tensile stresses to high compressive stresses. The constitutive matrix of a ...
