摘要
矮塔斜拉桥是国际上一种新型的桥梁结构,具有跨越能力大、经济性好和造型美观等特点。以某实际工程矮塔斜拉桥为例,运用有限元软件MIDAS/CIVIL对该结构进行有限元建模,并对其进行动力特性分析,得到该结构的自振频率和振型,该研究可为矮塔斜拉桥的抗震设计提供参考。
Extradosed cable-stayed bridge is a new bridge structure in the world,with large span capacity,good economics and beautiful appearance. With a practical project of extradosed cable-stayed bridge as an example,the finite element software MIDAS / CIVIL is used to establish the finite element modeling of the bridge and the dynamic property of extradosed cable-stayed bridge is analyzed,then the natural vibration frequency and vibration mode of the bridge are obtained. The study can provide references for the aseismic design for extradosed cable-stayed bridge.
