摘要：
The tests of joints are completed, including the ultimate bearing capacity tests on K type concrete-filled rectangular steel tube truss joints. The nonlinear finite element model of concrete-filled rectangular steel tube truss joints is also built. Steel tubes, concrete within tubes and the interface between steel and concrete are modeled by shell, 3D entity and contact element in finite element model, respectively. The constitutive model of steel tubes and concrete is elastic-plastic, while the interface is described by column's friction law. The nonlinear finite element numerical simulation calculation of concrete-filled rectangular steel tube truss joints is performed. The results keep in with those from tests.
