服役工业厂房风险分析方法探讨

Study on risk analyzing method for existing industry building

以概率与数理统计学为基础,考虑时间因素,探讨了服役工业厂房风险分析中失效损失程度概率分布的数学模型及其统计方法和相关参数取值,结合抗力衰减概念将其引入服役工业厂房的风险分析中.算例分析表明:按此方法计算的风险值要高于常规方法计算的风险值,使对服役工业厂房的风险分析更加符合实际.

Based on probability theories and time effect, a thorough study on the probability function model of failure loss degree, its statistics method and the choice of corresponding parameters is carried out. The model, combining the concept of resistance attenuation, is applied to the risk analysis of existing industry concrete buildings. A case study indicates that the risk value calculating with the paper's method is higher than that with the common method. It is concluded that the method of the paper is more reasonable in practice.
