原始语种摘要: Through the monitoring of the displacement of the middle accross section in concrete filled steel tube (CFST) arch with 0.26 rise-span ratio, which fixed at both ends under the condition of uniform loading, as well as the strain and the ultimate bearing capacity of outer steel pipe and inner core of concrete which combined with ABAQUS for simulation analysis of bending process. Meanwhile, based on the ABAQUS simulation software with cohesive elements as the main research method in the constitutive model of concrete was put forward. The actual simulating and experiment results shows that the local failure characteristics of core concrete of CFST arch is similar to those of uniaxial compression on concrete short columns, and there is only compressive stress exists among the middle accross...
