| 摘 要： | 采用时程分析法,对三向地震动作用下的波形钢腹板混凝土箱拱新型结构的地震特性进行分析,通过与混凝土腹板的混凝土箱拱动力特性和地震响应特点的对比,得出该新型拱圈结构具有较优越的抗震性能。同时,把三向地震作用的结果与在两个主方向(纵桥向和横桥向)同时施加地震动的计算结果进行比较,得到竖向地震动对波形板箱拱地震响应的影响程度。

| Abstract: | The seismic analysis of a new arch structure subjected to three-directional ground motions,which is the reinforced-concrete arch bridge with corrugated steel webs,is carried out by using the time-history analysis method.Comparing with the reinforced-concrete arch bridge with concrete webs,the new arch structure has a better dynamic and seismic performance.Then,the effect of vertical ground motions on the arch bridge with corrugated steel webs is discussed by a comparison of the seismic responses from the three-directional ground motions and the two-directional(transversal and longitudinal direction) ground motions. |
