摘要
结合几座钢管混凝土拱桥的动力测试和有限元动力计算结果 ,分析了钢管混凝土拱桥的自振频率、振型及阻尼等动力特性 ,并对结构的动力设计提出建议。
The dynamic characteristics including self vibration frequency, mode of vibration and damping of concrete filled steel tubular arch bridges are analyzed with the results of dynamic tests and finite element calculations of several such bridges. Some suggestions about the dynamic design of the structure are presented.
