摘要
如今轻型门式刚架被广泛应用,但在规范及文献中对门式刚架的整体抗震性能均未作出明确的规定。本文利用ANSYS对门式刚架进行有限元分析,重点研究门式刚架在循环荷载下的破坏机理,承载能力及变形能力,以用于评价门式刚架的整体抗震性能及设计的合理性。
Lightweight portal frame is widely applied now, however seismic performance of Lightweight portal frame was not clearly defined in hysteretic and literature. In this paper, ANSYS is used to make finite element analysis of the portal frame, this paper focuses on the portal frame＇ s Failure mechanism, carrying capacity and deformation capacity under cyclic loading, is proposed to estimate the seismic capacity and design rationality.
