摘要：
The mechanical behavior of concrete-filled steel tubular column (CFSTC) joint was modeled and analyzed using the finite element software ANSYS. The problems were taken from the substantial structure of a subway station located in Futian, Shenzhen, China. Different types of joints used in the structure, including column capital and transverse beam joint, column footing and downward beam joint, and column and ground floor beam joint, were modeled under various loading conditions namely, bending moment, shear forces and axial forces. Distribution of principal stress, shear stress and deformation of the CFSTC joint as well as its components, including the steel columns, beams, reinforcing ring, pile cap and uplift pile etc, were analyzed and compared with the allowable strengths. Then an improved structural design and reinforcement scheme was proposed.
