| Abstract: | There are two main kinds of approach to simulate the dynamic behavior of the concrete filled steel tubular(CFST) frame structures,i.e.,three dimension finite element method and fiber model based on nonlinear fiber beam-column.The three dimension finite element method is limited to be used because of it's computational efficiency and convergence.In order to study the seismic performance of the CFST frame structures,the nonlinear fiber beam-column element based on the OpenSees platform is used in this paper.A... |
