几种边界约束条件下受火钢梁行为的比较分析
Comparative analysis of different restrained beams in fire condition
摘要
Abstract
Based on FE simulation, this paper presents the numerical results of the behavior of steel beams at elevated temperature. The developing course of the behavior of steel beams with several extreme restraints such as simply, hinged and fully supports is systematically investigated, as well as its critical temperature. Furthermore, some detailed parametric analysis is described, including beam span, different levels of applied load and load types. The results show that the boundary conditions can significantly affect the behavior of steel beam in fire; otherwise, the load ratio and beam span have great influence on the behavior of restrained beam while the influence of load types is little, even can be neglected .关键词
