室内火灾性状的计算机模拟研究

Study on the Computer Modeling of the Properties of Indoor Fire

本文通过使用室内火灾热平衡方程，运用计算机模拟技术，重点讨论了实际室内火灾状态下的温度－时间曲线随火灾荷载、开口因子、开窗率、壁面导温系数等影响参数变化而变化的规律，并以当量时间来判定温度对建筑构件的损伤程度。

With the help of the heat balance equation of indoor fire, the paper mainly discusses the changing law of temperature-time curve under the condition of the real indoor fire with the changing parameters such as fire load, opening factor, opening ratio of the window, thermal conductivity of the wall surface etc. by using computer modeling technology. The damage of the temperature to the building elements is judged by using equivalent time.
