Application of PDS-FEM to Seismic Failure Analysis of Reinforced Concrete Bridge Pier
Abstract eng: Particle-Discretization-Scheme (PDS) is a new discretization scheme which uses a pair of basis functions that discretize a function and its derivatives using characteristic functions, and PDS-FEM is an FEM which is implemented with PDS. It is straight forward to numerically solve a crack problem by means of PDS-FEM. This paper presents an application example of PDS-FEM to seismic structure response analysis of an RC bridge pier. A sophisticated non-linear elasto-plastic constitutive relation is used for concrete, and a detailed model is made. It is shown that the processes in which the pier is damaged and partially failed due to seismic loading are computed. Large plastic deformation as well as initiation and growth of local cracks in concrete are computed.
