摘要:
基于Maxwell模型,以斜拉桥为研究对象,建立有限元模型,沿纵桥向在塔梁间设置液体粘滞阻尼器.以结构关键部位的响应控制为目标,基于地震响应控制原理,应用非线性时程分析法,计算分析结构附加液体粘滞阻尼器后的动力响应,探讨在地震作用下时液体粘滞阻尼器对结构的减震效果及其敏感参数规律.结果表明,设置阻尼器后,结构关键部位的位移、内力响应明显减小,其中速度指数对结构减震效果影响较大,当其在0.3~0.5范围内,阻尼器的非线性较强,减震效果更优.在地震作用下,斜拉桥附加合理力学参数的液体粘滞阻尼器后,具有良好的减震效果.
Abstract:
Based on Maxwell model,the cable-stayed bridge is taken as the research object,and the finite element model is established.And viscous liquid dampers were set between tower beams along the longitudinal bridge.Based on the seismic response control principle,the nonlinear time-history analysis method is applied to calculate and analyze the dynamic response of the structure with the added fluid viscous damper,and the damping effect of the fluid viscous damper on the structure and the law of its sensitive parameters are discussed.The results show that the displacement and internal force response of the key parts of the structure are obviously reduced after the damper is set.The speed index has a great influence on the structure damping effect.When it is in the range of 0.3-0.5,the stronger the nonlinear of the damper,the better the damping effect.Under the action of earthquake,the cable-stayed bridge has good damping effect after adding liquid viscous damper with reasonable mechanical parameters.
