Dynamic Analyses of Semi-Rigid Connection Low Yield Point Steel Frames

Abstract:

Based on the analysis for 10 series (altogether 50) of finite element analytic models, the time-history analysis is discussed in this paper to investigate the relations between frame parameters of semi-rigid steel frames, these parameters include the frame's floor number, the frame's span number, especially the rotation stiffness of beam-to-column connections. Comparing with the steel frame structure, the ductility of semi-rigid steel frame structure is improved with the reduction in the rotation stiffness of connections. Furthermore, semi-rigid steel frame structure under seismic loads has a good seismic performance.
