Abstract: In order to verify the mechanical properties of the key joints of a certain special engineering of steel-concrete composite structure system, key joints were analyzed by ABAQUS nonlinear software. The result of theory analysis was compared with experimental study. Some reasonable suggestions were presented for design of steel-concrete composite structure system and joints.

Keywords: steel-concrete composite structure; nonlinear ; key joint
