摘要:
针对钢-混凝土叠合梁自锚式悬索桥的结构特点,在总结以往大跨径桥梁有限元模型的基础上,采用组合有限元法以梁、板、杆、索单元建立邵阳市桂花大桥三维有限元模型,计算分析获得结构的主要频率和振型。通过现场测试获得大桥环境激励和行车激励作用下的响应时程,分析得到结构的主要频率、振型和阻尼比,引入模态置信因子对计算模态信息和实测模态信息进行比较分析,以验证数值模型和实测结果的准确性。研究结果可为全面了解钢-混凝土叠合梁自锚式悬索桥的动力特性、准确预测结构的动力响应以及类似桥梁的抗震、抗风设计提供重要依据。
Abstract:
Based on the previous dynamic analysis models and the structure characteristics of self-anchored suspension bridge with steel-concrete composite girder, a new 3D FEM model is built up for the Guihua bridge, which includes beams,plate,bar and link elements,and the several main frequencies and modal shapes were obtained through modal analysis procedure.Time response histories of the bridge under the ambient excitation and vehicle excitation were recorded. The main frequencies, modal shapes and corresponding damping ratios of the bridge were obtained by of the field testing.MAC was employed to compare the calculated modal information with them extracted from the dynamic testing. The accuracy of the numerical model was evaluated. The results can be used to understand the dynamic behavior of the self-anchored suspension bridge with steel-concrete composite girder and to predict the dynamic response of the bridge in future studies.
