Abstract: In order to study the aseismic behavior of concrete-filled rectangular tubular repaired structure, the hysteretic behavior under cyclic loading is analyzed based on a quasi-static test of a two-span, three-storey concrete-filled rectangular steel tubular repaired frame (CRSTRF). Based on the hysteretic curve, the top layer framework curve and the corresponding resilience model are obtained. The ductility characteristics, stiffness and strength degeneration are studied. Nonlinear finite element method is adopted in applying the resilience model to the degeneration equation of concrete elastic module and the numerical simulation of the test is carried out. The results show that a good agreement is reached between the theoretical analysis and available experimental results.
