加拿大卡尔顿大学开发了火灾风险计算机模型CUrisk,用以评估四层木结构商品建筑的火灾安全设计。该模型包括系统模型和许多子模型。系统模型用于设定风险分析框架及控制子模型数据流。它还负责计算每个火灾场景的生命危险值。其他子模型包括火灾增长、烟气运动、边界失效火灾蔓延、人员反应和疏散以及建筑造价和经济损失等模型。利用子模型的输出数据,系统模型可计算三个决策参数:对生命的预期风险、对受伤情况的预期风险以及消防成本预期。这些参数是以可能的火灾场景及相关概率为基础的。文章简要介绍了CUrisk模型,并介绍了运用该模型对四层商业建筑所进行的多火灾场景风险分析的结果。
Carleton University in Canada developed CUrisk, a computer model of fire risk, to evaluate the fire safety design of four-storey wooden commodity buildings. The model includes the system model and many sub-models. The system model is used to set the risk analysis framework and control sub-model data flow. It is also responsible for calculating the value of life-threatening for each fire scene. Other sub-models include models for fire growth, smoke movement, the spread of border-dead fires, personnel reactions and evacuation, and construction costs and economic losses. Using the sub-model's output data, the system model calculates three decision parameters: the expected risk to life, the expected risk to an injured condition, and the expected cost of firefighting. These parameters are based on possible fire scenarios and related probabilities. The article gives a brief introduction to the CUrisk model and presents the results of a multi-fire scenario risk analysis of four-story commercial buildings using this model.
