| 摘 要： | 根据钢管混凝土统一理论，对国内某中承式钢管混凝土拱桥建立的模型进行了动力特性研究，并用时程分析法对其进行了地震响应分析。探讨了3种不同横撑设置方式对桥梁的影响，通过对计算结果分析发现横撑设置的变化能改变桥梁横向刚度，从而在一定程度上提高了桥梁抗震性能。得出的结论可以为同类拱桥的抗震设计和研究提供参考依据。

| Abstract: | According to the unified theory of concrete-filled steel tube, the model of a semi-supported concrete filled steel tubular arch bridge is established for analyzing the dynamic property. And the method of time-history analysis is used in the analysis of seismic response of this bridge. Then three different ways of transverse braces layout is discussed. The conclusion from analysis of computed results may be helpful to the seismic designation and study on the same series of bridges. |
