【摘要】 大跨度连续梁桥一般只设置一个固定墩,在地震荷载作用下,纵桥向的地震荷载的绝大部分由固定墩来承受.通过对一座实际大跨度连续桥梁的地震反应分析,讨论了不同支座类型对其结构动力特性及地震反应的影响.更多还原

【Abstract】 Due to the large- span continuous girder bridges only installing a fixed pier. And bridge bearing is vulnerable in earthquake , the fixed bearing of the large - span continuous girder bridges almost undertaked all the seismic load . however,based on a real large - span continuous girder bridge, the paper studied the different type of bearings influenced on structural dynamic property and seismic response更多还原
