摘要
为了评估公共建筑在地震后的安全性能,提出了基于建筑信息模型(BIM)和美国下一代性能评估方法 FEMA P-58的地震次生火灾模拟方法。在该方法中,建立了基于BIM建筑火灾数值模型快速建模方法,并开发了水炮和排烟风机的数值模型;提出了基于FEMA P-58的消防设施震害预测方法。实现了石家庄国际展览中心在典型地震情景下的地震次生火灾模拟,结果表明该展览中心震后排烟性能下降,但满足人员疏散要求。
To assess the fire protection performance of public buildings after earthquake,a simulation method on post-earthquake fires was proposed based on building information model(BIM)and FEMA P-58(the next-generation building seismic performance assessment methodology of USA).In this method,a modeling method based on BIMs was established to quickly create the fire numerical model of a building,and the numerical models of water cannons and smoke exhaust fan were developed;a prediction method of the seismic damage of the fire protection facilities was proposed based on the FEMA P-58.A post-earthquake fire simulation of Shijiazhuang International Expo Centre was performed under a classic earthquake scenario.The results indicate that the performance of smoke extraction decreases but can meet the requirement of people evacuation.
