The 3D free vibration properties of the cable stayed bridge on Wuhu Yangtze River bridge, which is of 180 m+312 m+180 m span, are analyzed by space bar FEM model and also by space bar slab solid hybrid FEM model.

• 针对芜湖长江大桥主桥 180 m +312 m +180 m的斜拉桥 ,分别采用空间杆系有限元模型与空间杆系 -板-实体混合单元有限元模型分析了桥梁的空间自振特性 ,两种模型的计算结果取得了较好的一致。
