Post-earthquake fires occur frequently, and the seismic damage to non-structural components results in dangerous fire and evacuation environments. Both firefighters and trapped people will face serious threats to life during the rescue. Consequently, a simulation framework of an indoor post-earthquake fire rescue scenario based on building information model (BIM) and virtual reality (VR) is proposed herein. Information of structural and non-structural components is extracted from the BIM. Subsequently, the seismic damage of non-structural components is predicted according to the time-history results and fragility curves. Moreover, a smoke visualization method combining volume rendering and the particle system is also proposed. A case study of a 19-story hospital is conducted using the proposed method for establishing the fire rescue scenario. The results show that the established VR scenario has high realism and smooth interactivity, and the influence of smoke on the fire rescue is more significant than that of fallen debris.

地震后经常发生火灾，非结构性组件遭受地震破坏会导致火灾和疏散环境。营救过程中，消防员和被困人员都将面临严重的生命威胁。因此，本文提出了一种基于建筑物信息模型（BIM）和虚拟现实（VR）的室内震后火灾救援场景的仿真框架。结构和非结构成分的信息是从BIM中提取的。随后，根据时程结果和脆性曲线，预测非结构性构件的地震破坏。此外，还提出了一种结合体绘制和粒子系统的烟雾可视化方法。使用所提出的方法建立消防救援场景，对一家19层医院进行了案例研究。
