| 摘 要： | 以京珠高速公路郑州黄河大桥主桥为研究对象,采用ANSYS有限元程序,建立该下承式钢管混凝土拱桥的空间有限元计算模型,分析不同吊杆损伤对桥梁自振特性的影响,计算结果表明,吊杆损伤对该拱桥的自振频率影响较大,吊杆损伤导致桥梁竖向和扭转自振频率降低.计算结果可为桥梁使用阶段的健康检测和维护提供参考.

| Abstract: | Taking the main bridge of Zhengzhou Huanghe River Bridge on Beijing-Zhuhai Expressway as the research object,this paper sets up a three-dimensional finite element calculation model for the concrete-filled steel tube through arch bridge by means of finite element analysis software ANSYS and analyzes the influence of different cases of suspender damage on the natural vibration characteristic of the bridge.The results of calculation reveal that the suspender damage has considerable influence on the natural vib... |
