摘要
采用有限元数值分析方法,对立体桁架屋盖结构在不同参数影响下的抗火性能进行了研究,得出了立体桁架结构中杆件应力随温度增长的变化规律以及不同参数对立体桁架抗火性能的影响,旨在为立体桁架屋盖结构的性能化抗火设计提供依据。
The paper adopts the finite element numeric analysis method, researches the fire-resistance performance of the three-dimension pipe truss roof structure affected by parameter, concludes the changes law of the member stress ratio with the increasing temperature in the three-dimension pipe truss structure, so as to provide some reference for the fire-resistance design for the three-dimension pipe truss roof structure.
