| Abstract: | Steel initial stress is a matter of interest to engineers and technicians when concrete filled steel tubular (CFST) structures are used in long span bridges and highrise or superhigh buildings. Based on the steel follow up strengthening and concrete bounding surface constitutive relationships, this paper writes a nonlinear finite element program for calculating complete curve of CFST compression bending trosion members under the initial stress. It has many characteristics such as in selecting constitutive relationships, setting the finite element model and solving the nonlinear point, so it not only saves many calculating time but also solve the actual engineering matters satisfactorily. |
