In order to reflect the true state under seism about the long-span composite truss frame, the analysis should embody the initial influence of static loads.

This paper sets up the FEM model of the composite structure through ANSYS, simulates the floor, truss, shear connector by the shell, rigid frame and connector elements.

The utility model relates to a composite concrete jumbo beamcolumn frame with built-in steel truss, belonging to a jumbo frame structure system applied in the high-rise building.
