摘要
通过对我国京沪高速铁路设计中的一座三跨预应力混凝土斜交箱形连续梁桥缩尺模型自振特性参数的测试 ,比较了正交、斜交箱梁的固有频率的差异 ,通过与空间结构分析结果的对比 。
Vibration Characteristics test was carried on a model of one three spanned prestressed concrete(PC)shew continuous box girders,which was designed in Jing Hu high speed railway of China.We discuss the difference between the results of test and 3D FEM analysis with two cases of orthogonality and shew,and explore the dynamic properties of skew box girders.
