Abstract:Structural system of concretefilled steel tubular column and steel reinforced concrete beam is used in Futian Railway Station to support the large span underground structure. Static load test of the joint between concretefilled steel tubular column and steel reinforced concrete beam was carried out. The test scheme was introduced and the joint crack and failure mode were summarized. The joint was analyzed by the finite element method. It is proved that the test results of load\|deformation and load\|strain are close to the results of the numerical simulation by comparative analysis. The structural system can be applied in the similar underground structure.

Keywords:concretefilled steel tubular column； steel reinforced concrete beam； joint； finite element method
