现行规范中荷载分项系数的比较及修定建议

The comparison and suggestion on the partial coefficient for the loads in the current criterion

根据概率极限状态计算原则 ,计算了综合考虑三种不同荷载效应组合与单独考虑各荷载效应组合下的最优荷载分项系数 ,比较得出现行规范中取用荷载分项系数的利弊 ,并提出了相关修订建议 .

According to the Probabilitybased limit state design method, the optimum partial coefficient for the loads under the integrated consideration of three different loadeffectcombinations and that under the consideration of each loadeffectcombination, were calculated in the paper. The advantages and disadvantages of the partialcoeffient for the loads in the current criterion were compared. And eorrelative method of modification was put forward.
