- Abstract
Traditional welded joint in steel frame design can be seen as completely rigid joint. And the high strength bolt end-plate joints have been used with popularity in multi-story frames because they have the advantages of requiring shorter assembly times, better seismic performance and good ductility. The performance of this kind of structure model under the condition of progressive collapse has not been analyzed. So, this paper aimed to solve this problem. ANSYS is applied in this article for the analysis of the performance of the capacity of unilateral extended end-plate connections through the method of numerical simulation and comparing with rigid joint. Then applying corner-general force curve of semi-rigid joint to the numerical analysis by using SAP2000. Establishing separate frames with rigid joints and semi-rigid joints, and analyzing the performance of each frame in the condition of progressive collapse. The analysis results show that the resistance of steel frame with semi-rigid joints is superior to rigid frame structure. It has better ductility, and is conducive to the further development of catenary stage.
