摘要

摇摆墙体与主体框架之间存在较大的竖向变形,可于此变形集中部位增设耗能构件,实现保护主体结构的基本损伤机制。本文提出附加阻尼的框架-摇摆墙结构,并基于等效线性化理论初步计算结构仅附加单一类型阻尼器的阻尼置放量,而后通过定义目标函数,确定可使目标函数最小的同时附加粘滞阻尼与金属阻尼的阻尼器布置方式,得到结论如下:(1)于弯剪型结构,当仅考虑结构加速度控制时,可沿结构总高布置粘滞阻尼器,而需综合考虑结构楼层位移、加速度时及层间位移角时,可于结构2/3处下部安装金属阻尼器,与其上部1/3处安装粘滞阻尼器;(2)于剪切型结构,当仅考虑结构层间位移角时,可于结构楼层1/2处下部安装金属阻尼器,与其上部1/2处安装粘滞阻尼器,而需综合考虑结构楼层位移、加速度及层间位移角时,则可于结构1/3处下部安装金属阻尼器,与其上部2/3处安装粘滞阻尼器。

Abstract

For the large vertical displacement between the frame and rocking wall, energy consumption components should be added to protect the main structure. Based on this, additional damping frame-rocking wall is proposed and structural single type of damper amount also could be calculated through the equivalent linearization theory, by defining the objective function, the best damper layout of structure with viscous damper and metal damper which can make the minimum value of the function could be determined, and conclusions are as follows: (1) for the shear-bending structure, the viscous damper can be arranged along the total height of structure when acceleration is considered and the metal damper arranged at two thirds the lower part while the viscous damper arranged at one third the upper when displacement, acceleration and storey drift are considered; (2) for the shearing structure, the metal damper arranged at half the lower part while the viscous damper arranged at half the upper when storey drift is considered, in addition, the metal damper arranged at one third the lower part while the viscous damper arranged at two thirds the upper when displacement, acceleration and storey drift are all considered.
