摘要:
通过对建筑火灾的背景分析和研究现状的回顾,指出了进行建筑火灾可靠性研究的必要性。介绍了蒙特卡罗随机有限元计算的基本原理、随机数的产生办法和模拟次数的确定,最后作者采用通用有限元程序ANSYS计算了混凝土简支梁在不同温度、保护层厚度和荷载下的火灾可靠性。
Abstract:
Reviewing the background of building fire and the research status quo of the concrete structure under fire,this paper points out the necessity of the research on reliability of buildings underfire.The principle of Monte-Carlo stochastic finite element method,the production of random figure and the determination of smiulation tmies are introduced.At lasta, concrete simple beam under fire is smiulated using general purpose finite element program ANSYS.The reliability of the beam under fire is computed as an example for different temperatures,load conditions and coverage depths.
