大型减隔震桥梁结构分析方法
|
摘要
采取减隔震措施满足大型桥梁结构抗震要求的设计方法近年来得到了普遍的认同,对大型减隔震桥梁减隔震设计分析中涉及到的关键问题进行了探讨,在阐述国内外桥梁减隔震设计研究现状的基础上,总结了作者近年来的工作成果,提出了解决方案及原则建议.作为结构地震反应激励源的地震动输入,应能同时具有工程场地针对性和反映大型桥梁结构时、空效应的特殊性;建立合理可靠结构分析模型的难点是充分考虑模型的非线性,结构阻尼比、桩-土共同工作以及连接构件的模拟方法也是建模过程中必须重视的内容;选择求解减隔震结构地震反应的力学分析方法的前提是能准确描述结构非线性反应过程,但同时也应能兼顾到高效、快捷.
In design,isolating the seismic load to meet anti-seismic design requirements of the large-scale bridge structure was generally recognized in recent years.Some key issues in seismic isolation bridge design were discussed.The status quo of the seismic isolation design on the bridge was expounded.Then solutions and recommendations were principlely proposed.As the excitation source for structural seismic response,earthquake dynamic input should be aimed at certain specific site.At the same time the particularity of space effects and time effects of the large-scale bridge structure is reflected.To establish a reasonable and reliable structure analysis model,the nonlinear model should be considered.Several items,such as the structural damping ratio,the pile-soil cooperation,and simulation method of connect components in the simulation modeling were important.The structure of the nonlinear process should be described accurately when the earthquake response of seismic isolation structure was analyzed.Mean while the high efficiency and the convenience should be considered.
