Analysis on Dynamic Characteristics of Y-shape Bridge Based on Grillage Theory

摘要:

基于梁格理论采用通用有限元程序软件SAP2000对典型人字形桥梁结构的振动频率及振型进行了模拟分析,并讨论了主要结构参数对其动力特性的影响,可为人字形桥梁的动力设计提供参考。

Abstract:

The structure of Y-shape Bridge is an effective way for solving the city traffic problem. Based on the grillage theory and using common finite element software SAP2000, the vibration frequency and shaking type of structure of Y-shape Bridge are analyzed, and main structure parameter, impacting on its dynamic characteristics are discussed. The result could be a reference for the design of Y-shape Rridge.
