非对称Y型大悬臂式混凝土结构的地震响应分析

Seismic Response Anaylsis of Non-symmetric Y-type Cantilever Concrete Structure

非对称Y型大悬臂式混凝土作为一种新兴的工程结构,在桥梁结构工程中得到广泛的应用。对地基-大悬臂混凝土结构建立了三维模型,并运用有限元的动力分析方法,对其进行了动力响应分析,得到混凝土结构悬臂端在地震波时刻的位移响应和应力响应,分析了在三种抗震烈度下,结构悬臂端的行为,为工程抗震性能评估提供了参考依据。

As a new engineering structure,non-symmetric Y-type concrete structure has been widely applied in bridge engineering. In this paper,the three dimensional of large cantilever concrete structure is analyzed by finite element dynamic analysis method. The displacement response and stress of the concrete cantilever are obtained,at the same time,the behavior of concrete cantilever is analyzed under three different seismic intensity.
