Investigations On Material Constitutive Models Of Three-Dimensional Nonlinear Finite Element Analysis On Rc Structures

In this paper, the constitutive models of concrete, steel and bonding-slip for three-dimensional finite element analysis (3D-FEA) and its application are discussed. The subroutine of DIANA is developed and nonlinear 3D-FEA of RC beam and columns are carried out to verify above models. 3D-FEA results have good agreements with the test results. Therefore, it can be concluded that 3D-FEA can simulate the nonlinear behaviors of RC structure and members, in which constitutive models of concrete, steel verified in this paper are applied.
