摘要
Abstract
Considering the steel ratio, slenderness ratio, and the material strength as the main variable parameters, based on the determination of the stress-strain relation of the steel and core concrete under the cyclic loading, use the finite element software ANSYS to calculate the concrete-filled rectangular steel tubular columns under cyclic loading in the whole process, which simulates the mechanical properties of concrete-filled rectangular steel tubular columns in actual earthquake. Research shows that: the load versus displacement hysteretic curves of concrete-filled rectangular steel tubular columns was relatively full "spindle" .without obvious pinch phenomenon. After the limit load, model structure still showed good ductility and post-deformation. The concrete-filled rectangular steel tubular columns can meet the requirements of the real projects with large span and heavy load.关键词
