摘要
桥梁结构的动力特性(固有频率、振型)是结构动力分析、抗震分析的重要参数,是进行谐响应分析、谱分析和瞬态动力学分析的基础。采用ANSYS有限元软件对某独塔单索面斜拉桥的振动频率及振型进行分析,并讨论其主要结构参数对其动力、抗震性能的影响,为某桥的动力、抗震设计提供参考。
The dynamic performance of the bridge structure(natural frequency, vibration mode) is an important parameter for structure dynamic analysis and seismic analysis, and is the basis for harmonic response analysis, spectrum analysis and transient dynamic analysis. The ANSYS finite element software is used to analyze the vibration frequency and vibration mode of a single-pylon single-plane cable-stayed bridge. The article discusses the influence of the main structural parameters on its dynamic and seismic performances, which can be referenced for the dynamic and seismic design of this bridge.
