作者对之前开发的原型模型进行了改进，以模拟受地震影响的城市地区的火灾蔓延行为。在新模型中，地震运动和火灾加热都被认为是建筑构件损坏的原因。损坏会影响着火建筑物的燃烧行为以及建筑物之间的火灾蔓延行为。为了验证新模型，对 1995 年神户地震后的火灾蔓延进行了模拟。将数值模拟获得的火势蔓延行为与观测数据进行了比较。关于被烧毁建筑物的数量达成了合理的协议。
The prototype model previously developed by the authors was improved in order to simulate the behavior of fire spread in an earthquake-affected urban area. In the new model, seismic motion and heating by fire are both considered as the causes of damage to building components. The damage affects the burning behavior of a fire-involved building, as well as the behavior of building-to-building fire spread. For validation of the new model, a simulation of the fire spread that followed 1995 Kobe earthquake was conducted. The behavior of the fire spread obtained by the numerical simulation was compared with the observed data. Reasonable agreement was obtained with regard to the number of burned buildings.
