摘要
结合实际工程,利用有限元原理,对混合梁斜拉桥的动力特性进行分析,计算出一座混合梁斜拉桥的前十阶自振频率及其对应的振型,并结合混合梁斜拉桥的结构特点,重点分析了边跨辅助墩的设置对结构动力特性的影响。
Combined with the practical projects,the article analyses the dynamic characteristics of a compound beam cable-stayed bridge by the finite element principle,calculates the foremost 10 natural vibration frequencies and the corresponding vibration types of a compound beam cable-stayed bridge,and focuses analysis on the influence of installing the supporting piers at the side span on the dynamic characteristics of the structure according to the structure characteristics of compound beam cable-stayed bridge.
