考虑目标使用期的地震作用组合的分项系数
Partial factor in load combination of earthquake action considering the target period of usage
【摘要】 以概率理论为基础的概率极限状态设计方法已成为国内外主要的结构设计方法。以可靠度理论为基础,通过引入目标使用期,对地震作用组合的分项系数进行修正,并编制了相应的程序,对修正后的荷载组合的可靠度水平进行了验证。
【Abstract】 Probabilistic limit state method based on the probabilistic theory has been accepted worldwide.Based on reliability theory,by introducing the target period of usage,the partial factor in load combination of earthquake action has been correspondingly modified in this article,and the verification of reliability level of modified load effect has been obtained by compiled programs.
