摘要
本文运用有限元方法以一座 6× 50m的连续梁桥为工程背景 ,采用二级设防两阶级设计思想 ,即设计地震 (50年基准期、1 0 %超越概率 )作用下的强度验算和罕遇地震 (50年基准期、3 %超越概率 )作用下的延性验算 ,进行了地震反应分析及抗震性能评价。
This study aims to clarify the earthquake response analysis of a 6×50m continuous beam bridge and give the evaluation of its earthquake resistance performance. The finite element method is performed, and the analysis adopts the methodology of two-level defence and two-stage design, that is, the level of 10% probabilities of exceedance in 50 years(P1) is adopted to control the strength of the structure, and the level of 3% probabilities of exceedance in 50 years(P2) is adopted to control the ductility of the structure.
