钢管混凝土拱桥动力特性分析研究

On analysis research on dynamic performance of concrete filled steel tube arch

通过对祁家黄河混凝土拱桥动力特性的分析研究,阐述了现代拱桥随着跨度的不断增大和结构形式的复杂化,在材料轻质高强新型化的基础上,如何保证桥梁结构在动力荷载作用下能安全正常的完成整个设计运营状态,确保桥梁的安全性和可靠性的研究方法。

According to the analysis research on the dynamic performance of Qijia Yellow River concrete filled steel tube, the paper illustrates modem bridges, along with the increasingly wider arch, the complexity of the structure and the new high-strength of materials, how to ensure the bridge structure to finish the whole design operation under the dynamic loading effect, and guarantee the research methods for the bridges＇ safety and reliability.
