Abstract:
Authors used nonlinear finite element method to calculate and produce the compression-strain relationship of concrete-filled steel tube specimens under different shrinkage function influence. The initial adhesive stress between concrete and steel tube was substituted for the influence of shrinkage function. Influences of lengthways shrinkage function, radial shrinkage function and both directions' shrinkage function on the compression-strain relationship of concrete-filled steel tube were summarized by analyzing the calculation curves. The results show that the shrinkage functions of concrete will decrease the proportion limit, yield strength and modulus of elasticity of high-strength concrete-filled steel tube specimen, and have a bad influence on the ultimate bearing capacity of concrete-filled steel tube.
