摘要
以青岛海湾大桥沧口航道桥为例,利用ANSYS有限元软件建立了斜拉拱桥三维空间有限元模型,并利用子空间迭代法对桥梁结构的自振频率和振型进行了计算与分析。计算结果可为该桥的设计、施工以及使用阶段的健康检测和维护提供参考。
Taking the Cangkou Navigational Bridge of Qingdao Bay Bridge as an example,a cable-stayed arch bridge three-dimensional finite element model is set up by ANSYS software,and the bridge structure self-vibration frequencies and mode shapes are calculated and analyzed by subspace iteration method.The calculation results can provide the reference for the bridge design,construction and detection of health and the maintenance in the use phase.
