摘要：
This paper presents a 3D nonlinear finite element method to analyze hysteresis behavior of simply supported steel-concrete composite beam under low cyclic reverse loading. The calculation method for damage variables of concrete under uniaxial load was proposed, the unloading rule of concrete was given, and the hysteretic stress-strain relationship of concrete and the cyclic constitutive model of steel were constructed. Finite element models of prism specimens of concrete, specimens of steel and simply supported steel-concrete composite beam were established through ABAQUS. The test results of hysteretic stress-strain relationship of prism specimens of concrete under uniaxial cyclic loading of compression or tension, hysteretic stress-strain relationship of specimens of steel under uniaxial cyclic loading of tension and compression, and the hysteretic load-deflection relationship of the simply supported steel-concrete composite beam, hysteretic load-slip relations of beam end and hysteretic load-lateral deformation curves of stud were analyzed, the analysis results are in good agreement with the experiment results from references.
