摘要
桥梁结构的动力特性是结构抗风性能和抗震性能研究的基础。以在建的某跨海大桥为工程背景,采用通用有限元软件ANSYS建立本桥空间有限元模型。计算分析了不同的索塔形状(双曲海豚塔和主直副曲海豚塔)斜拉桥的动力特性。分析结果表明:两种结构的斜拉桥的振型基本相同,但双曲海豚塔斜拉桥的频率较主直副曲海豚塔斜拉桥的高。
Taking a cross-sea bridge under construction as the engineering background, using the general finite element software ANSYS, this paper established the bridge spatial finite element model. It also calculated and analyzed the dynamic characteristics of cable-stayed bridge in different tower shapes （hyperbolic dolphin tower and main-straight vice-curve dolphin tower）.
