摘要:
采用Bouc-Wen滞回模型和库仑摩擦模型来模拟铅芯橡胶隔震垫和摩擦阻尼器的力学模型,建立了位移相关摩擦阻尼隔震结构运动方程.数值分析表明,在常规强震激励下,位移相关摩擦阻尼能减少隔震层位移,但会增加上部结构的层间位移和加速度反应;而在脉冲型近场地震激励下则不仅能显著降低隔震层位移,同时对上部结构的地震响应也有一定的减震效果.参数分析对位移相关摩擦阻尼器的三个主要设计参数的合理选取给出了建议
Abstract:
Seismic response reduction effect of displacement dependent friction(DDF)damping on base isolated structure with lead rubber bearing(LRB)is investigated. Bouc-Wen hysteretic model and Coulomb friction model are adopted to simulate the mechanical property of LRB and DDF damper respectively. Numerical analysis shows that the DDF damping can reduce base displacement but may increase the inter-storey drift and acceleration response of the superstructure. On the other hand, under the excitation of impulse-type near fault earthquake, DDF damping can significantly mitigate base displacement. Meanwhile the inter storey drift and acceleration response of the superstructure are also more or less reduced. Besides parametric analysis gives some suggestions on the proper values of the three main factors of the friction damper.
