Abstract
An overall structure composed of the steel frame and cold-formed thin-walled steel structure is analyzed based on the finite element method. According to whether to take the modelling of the cold-formed thin-walled steel composite walls and floors into consideration, and the difference between the actual (elastic) floor and rigid one, several models are established for comparison. Thus, the vibration periods, inter-story displacement angles under wind loads and horizontal frequent earthquakes and the internal forces of the steel frame under various load combinations of each model are obtained. The results show that the lateral stiffness of steel frame—cold-formed thin-walled steel structure is significantly improved compared with that of the pure steel frame structure. The assumption of rigid floor is suitable for the Mechanical behaviors based on the finite element method analysis of this kind of structure, and the bending moment and shear forces of the frame have been greatly reduced so that the cross sections of the steel beams and columns can be diminished to achieve better economy in practical engineering.
