摘要

摘要: 由于规范对失效概率的取值与实际情况不符,针对年失效概率考虑随时间其结构老化使可靠性降低,且是一个变加速增加的过程,对该过程采用新的线性递增进行模拟,在一定程度上符合客观情况。在桥梁结构设计基准期内,失效概率在结构老化进行阶段每年按10%线性增加,从而推出改进的年失效概率函数。

Abstract: The specification of the failure probability does not match the value with the actual situation. According tothe fact that the reliability of a structure would be reduced on its ageing with time, which was taken into accourct inthe fuilure probability, and was also an increasing process of changing acceleration, so a new linear increment couldbe used to simulate this process, which conformed to the objective situation to some extent. In the bridge designreference period, the failure probability in the aging phase would be linearly increased by 10% per year, by whichthe modified annual failure probability function was proposed.
