| 摘 要： | 本文结合南京长江第二大桥南汊桥和上海市杨浦大桥两个桥例 ,建立了有限元模型 ,在考虑边跨主跨跨径比、梁墩刚度、支座单元等影响因素的情况下 ,分析了结构的横桥向地震反应及其变化特征 ,以便为桥梁概念设计阶段结构总体抗震性能的考虑提供参考。 |
| 关 键 词： | 斜拉桥 横向地震响应 |

| Abstract: | With two examples of Nanjing No.2 Bridge and Shanghai Nanpu Bridge, the transverse seismic response of cable-stayed bridges is analyzed in this paper, considering the ratio of side span and main span, the rigidity ratio of beam and pier, the bearings, etc. We hope the paper will work as a reference for consideration of the anti-seismic performance of the overall structure in the stage of conceptual design. |
| Keywords: | cable-stayed bridge transverse seismic response |
