( Huasen Architecture ＆Engineering Design Consultants Ltd., Shenzhen 518054, China)Abstract: The fuute element modes for joints of steel truss-concrete core wall and joint of steel beam column were established with the software ABAQUS based on the project of the museum of contemporary art and planning exhibition in Shenzhen. Results indicate that the elastic-plastic nonlinear analysis considering large deformations can simulate the bearing behavior of joints satisfactorily and the joints are safe under the most damaging load case.
Keywords: joint of cantilever steel truss and core wall; large-span spatial structure; nonlinear; finite element analysis
