    摘要:
    為提升粘滯阻尼器的減震效果,減少計算量,提出1種以各層間平均位移比為目標函數的粘滯阻尼器優化布置方法。即將各樓層在正負方向的最大層位移的平均值作為各層的層位移,以此計算各層的層間位移,通過各層間位移的比例來布置、分配粘滯阻尼器。不同布置方案下,案例結構中的粘滯阻尼器的響應對比結果表明,本文的布置方案在取得良好減震效果的同時,計算更為簡便;相比于以層間位移比為目標函數的布置方法,采用本文的布置方法,結構的最大層間位移最大減震率、最大層間速度最大減震率、最大層間加速度最大減震率分別提高了109%、485%和441%。
    Abstract:
    A novel method of determining the number of viscous dampers per layer in a frame structure is proposed to enhance earthquake mitigation effect and reduce the amount of calculation.It is is an optimum approach taking the average displacement of the maximum layer displacement in the positive and negative directions as the layer displacement of each layer, and the ratio of the average displacement of each layer as an objective function.The interlayer displacement of each layer is calculated, and damper number of viscous damping in each layer is determined on the basis of the ratio of relative displacement between the layers.The results of the responses compared show that the new method has better earthquake mitigation effect and simpler computation.Compared with the method of interlayer displacement ratio as objective function,the proposed approach has improved the maximum earthquake mitigation effect in interlayer displacement, velocity and acceleration by 109%, 485% and 441% respectively.
