Open publisher page 0 citations

Abstract

Based on the viscoelastic stochastic FEM, built with FEM in space and scatter method in time, this paper proposed the plane finite element model of response analysis of concrete frame structures, in which a linear three parameter viscoelastic model was adopted. The program of finite element was developed and used in analyzing the response of concrete frame structures and the creep law of concrete. The numerical results indicate that this method has high precision and efficiency, and adapt to operation of engineering.
