Analysis of Elastic-Plastic Responses of a New Single-Story Frame-Bent Structure during an Earthquake Based on the Transfer Matrix Method of Multibody System

Abstract

Finite element methods, such as the ANSYS, are widely used as traditional structural dynamic analysis methods. Due to the low calculation efficiency of the ANSYS, there is a hindrance factor in using the finite element method to compute the elastic-plastic responses of special engineering structures. In this paper, we detail a pioneer study in which the transfer matrix method of multibody system (MS-TMM) was introduced to analyze the dynamic responses of civil engineering structures. Although the responses obtained by the MS-TMM are similar to the responses obtained by the ANSYS, the ANSYS requires a greater amount of computation time. The results indicate that the MS-TMM can satisfy the requirements of calculation efficiency and calculation accuracy.
