摘要
采用大型通用有限元程序ANSYS对大跨度连续刚构桥进行三维地震动态时程分析,分析比较不同桥墩结构形式对连续刚构桥抗震性能的影响。分析结果表明:与采用双肢薄壁实心墩的刚构桥相比,采用双肢薄壁空心墩的刚构桥其位移反应更大,各构件轴力以及面内弯矩减小,而各构件的面外弯矩均增大。
The ANSYS-based 3D time-history analysis of earthquake is applied to a continuous rigid frame bridge, and the influence of various piers on the seismic response of the bridge, It is Concluded compared to bridge with solid pier, bridge having hollow pier has a larger displacement, and the axial force and the in-plane moment are smaller, but the out-plane moment of each component is larger.
