摘要
总结了国内外变截面门式刚架抗震设计和地震反应研究的主要方法及研究现状,指出了我国开展变截面门式刚架进行地震反应研究的必要性和迫切性,针对我国现有规范(程)中变截面门式刚架抗震设计规定的不足,对变截面门式刚架的地震反应进行了研究分析,提出了变截面门式刚架地震反应分析和设计方法的研究方向。
This paper summarized the recent progress in the seismic response analysis and major earthquake design methods of the portal frame structures with tapered members at home and abroad, as well as pointed out the necessity and urgency to study the seismic response of this type of structure. In allusion to the insufficiencies of earthquake design items in some specifications for these structures in China, the paper carried out the research on seismic response of these structures under earthquake. And the future prospect of seismic analysis and design methods for these structures under earthquake is also predicted.
