摘要
通过有机结合FDS和ANSYS,采用热力耦合数值模拟的方法,对某钢筋混凝土建筑火灾倒塌案例进行再现分析。通过FDS模拟,获得现场温度随时间变化的情况以及火灾中压溃破坏的5根钢筋混凝土柱的时间-温度曲线。用ANSYS计算钢筋混凝土框架的不同温度下的变形和受力性能。研究结果可为灭火救援安全评估、建筑火灾荷载风险评估等性能化分析提供思路和方法。
By combining the FDS and ANSYS, and utilizing the numerical simulation of heat-force coupling, reproduced and an- alyzed the fire-collapsed case of a reinforced concrete building. By FDS, the change of temperature with time, and the timetemperature curve of 5 reinforced concrete column crushed in the fire were gotten. By ANSYS, the deformation and mechanical performance of the reinforced concrete frame under different temperature was calculated. The research can provide some new methods and ideas for the performance analysis on the security evaluation of emergency rescue and the issue evaluation of building fire load.
