【摘要】 对15层主结构与7层次结构的两相邻框架剪力墙模型结构在三个不同位置连接黏滞流体阻尼器,输入三种振动台地震波及三种不同加速度峰值,以主结构顶层最大相对位移最小为优化目标,寻求出三种阻尼器连接位置对应的最优阻尼系数,并对两相邻结构进行地震反应分析。结果显示,当阻尼器选择合适的安放位置和合理的阻尼参数时,主、次结构的地震反应都会有一定程度的降低,从而起到较好的减震效果。更多还原

【Abstract】 Two adjacent frame shear wall models,15-storey main structure and seven-layer sub-structure were designed.Selecting three kinds of locations for viscous damper,entering three kinds of seismic waves and acceleration peaks,it was aimed to get the optimal damping coefficient and damper parameters,with the target of minimal relative displacement at the top layer of the main structure.Besides,the seismic responses of two adjacent buildings were analysed.The results show that by selecting appropriate locations and damping parameters of dampers seismic responses of primary and auxiliary structures can be reduced to a certain extent.A better effect can be achieved in mitigating seismic responses of building structures.更多还原
