高温下门式刚架结构的有限元计算分析

FEA ANALYSIS OF PORTAL FRAME STRUCTURE AT HIGH TEMPERATURE

首先对高温下门式刚架结构的极限状态进行详细的阐述,然后建立火灾下高温门式刚架的有限元计算的理论模型,编制相关的有限元程序,对其高温下的变形进行相关的有限元计算分析,并与试验结果进行比较,验证了计算结果的正确性,为火灾高温下门式刚架的设计计算提供相关的指导理论依据。

Firstly the limit state of the portal frame structure at high temperature is described in detail,and then the FEA model of the portal frame structure at high temperature is established,and the FEA program is also compiled.The displacement of the door type steel frame structure under the high temperature is be calculated using this FEA program,and the results are verified with the test data. All of these can provide a basis for the design guidance to the portal frame structure at high temperature.
