| Abstract: | A method is presented for analyze the behavior of concrete-filled steel tubular (CFST) arch with truss ribs, which considering the material and geometric nonlinear property. A finite element program based on this method is introduced. In the program, beam element and combined CFST constitutive is used. The method of solution used is that of the mixed procedure (incremental method + modified Newton iteration). Using this method, to analyze a CFST arch with truss under the load, some useful conclusions are reached. |
