波纹钢腹板斜拉桥动力特性分析

摘要

Taking the corrugated steel web cable-stayed bridge as the engineering background,the paper analyzes the dynamic properties of the bridge structure by applying finite element software Midas/ Civil,and obtains the first ten vibration mode,frequency and cycle,so as to provide some theoretical basis for bridge seismic design and wind-resisting design.%以某波形钢腹板斜拉桥为工程背景，采用有限元软件 Midas／ Civil 对桥梁结构动力特性进行分析，得到前10阶振型、频率、周期，从而对桥梁的抗震设计及抗风设计提供理论基础。
