| 摘 要： | 结合宜宾长江公路大桥斜拉桥的工程设计实例,采用大型有限元分析程序A N SY S,选取空间BEA M 4、LIN K 8及M A SS21单元建立动力计算模型。用子空间迭代法对宜宾长江公路大桥主桥的动力特性进行了计算,根据桥址场地地震动参数,用反应谱法和时程分析法进行地震反应对比分析,并按桥规对结构进行抗震性能验算。结果表明,宜宾长江大桥主桥抗震结构体系采用弹性索体系是合适的。 |
| 关 键 词： | 宜宾长江公路大桥 斜拉桥 动力特性 地震反应 |

| Abstract: | An engineering design case about Yibin Yangtze River Highway cable-stayed bridge is investigated,using the finite element analysis program ANSYS.Element BEAM4?Element LINK8?Element MASS21 are used in the dynamic FEM.The dynamics characteristics of the main bridge of Yibin Yangtze River Highway bridge are analyzed by sub-space iteration method.According to the earthquake dynamic parameters of the bridge site the earthquake response is analyzed using the earthquake response spectrum method and the time history analytical method.And the aseismic capability check is processed according to bridge standards.The results of the analysis prove that the elastic cable system is appropriate for the seismic structure system of the main bridge of Yibin Yangtze River Highway bridge. |
| Keywords: | Yibin Yangtze River Highway Bridge cable-stayed bridge dynamic characteristic earthquake response |
