This paper simulates initial stress of steel tubes and self-stress of concrete by applying load of uniformly distribution surface and applying temperature load on concrete, establishes the entity model of concrete-filled steel tubular members by means of ANSYS finite element, and analyzes the laws of influences of initial stress of steel tubes and self-stress of concrete on concrete-filled steel tubular members, and on this basis fits computational equation for bearing capacity of concrete-filled steel tubular members. Relative to numerical result, this fitted computational formula has higher accuracy.
