Vibration reduction control method and system for super high-rise shear wall building residence
The invention discloses a vibration reduction control method and system for a super high-rise shear wall building residence. The method comprises the following steps: determining the arrangement position of a damper according to a shear angle corresponding to each sub-frame in a target building; determining the arrangement angle of the damper in the corresponding subframe according to the axial deformation corresponding to the damper; screening the sub-frames according to the arrangement positions, the arrangement angles and the refuge floor numbers of the sub-frames in a controlled mode and an uncontrolled mode, and determining a plurality of target sub-frames; and based on the target sub-frame, the vibration reduction rate corresponding to each refuge floor is calculated, the damping coefficient of the damper is modified according to the vibration reduction rate, and vibration reduction control is conducted on the target building. According to the method, wind vibration control of the shear wall residence under the long-term load effect is considered, variable-parameter damper design is provided for different working conditions, and the problem that in the prior art, it is not considered that the super high-rise building is likely to be subjected to the earthquake effect besides the wind load effect, and consequently the damper is prone to being damaged under the large earthquake effect is solved.
本发明公开了一种用于超高层剪力墙建筑住宅的减振控制方法、系统，所述方法通过根据目标建筑中各子框架对应的剪切角确定阻尼器的布置位置；根据阻尼器对应的轴向变形确定阻尼器在对应子框架的布置角度；分别在有控模式和无控模式下，根据布置位置、布置角度以及各子框架位于的避难层数对各子框架进行筛选，确定若干目标子框架；基于目标子框架计算各避难层对应的减振率，根据减振率修改阻尼器的阻尼系数，对目标建筑进行减振控制。本发明考虑长期荷载作用下剪力墙住宅风振控制并提出针对不同工况采取变参数的阻尼器设计，解决了现有技术中未考虑到超高层建筑除风载荷作用外还可能受到地震作用，导致阻尼器在大震作用下阻尼器易受到损耗的问题。
