Study on Seismic Response Analysis of 3-D Structure

This paper describes the parallel finite element analysis of large scale 3-D structural dynamic problems based on the Domain Decomposition Method (DDM) with preconditioner using Balancing Domain Decomposition (BDD) for massively parallel processors. This domain decomposition has been implemented within a finite element code for linear implicit transient dynamic analysis. Time integration is performed using Newmark-βconstant average acceleration method. The parallel finite element code uses an MPI-based message passing approach to provide portable parallel execution on shared, distributed and distributed shared memory computers. 3-D structural dynamic problems have been conducted on supercomputer to evaluate the performance of the implicit parallel linear finite element code. Results indicate that the proposed methods are highly adaptive for parallel computing and superior in performance.
