The light steel portal frames with tapered members have been the main structure form of single- story long-span industry and warehouse building in China. In this paper, the development of research on stability and seismic response of portal frame with tapered members at home and abroad is reviewed briefly, the progress in the research on theoretical analysis, experimental investigation, and design method for the stability and seismic response of the frame is introduced. Meanwhile the problems in these two aspects and its practical application are pointed out also. In allusion to the insufficiencies of stability and seismic design items in some specifications for these structures in China, some suggestions for the stability, the seismic response, and the ultimate bearing capacity judging method of this type of structure are presented. |
