本文提出了高层建筑三种风振控制方式(拉索,挡风板和可调质量阻尼器)的一个改进的设计方法。文中:建立了脉动风的成型滤波器,导得了基于结构层间位移、速度和加速度反应的扩展二次型目标函数的控制规律,实现了高层建筑强度,刚度和舒适度的控制要求,提出了消极控制的具体设计方法,采用了一种简单而实用的自适应控制方法,使主动控制得到实现。
This paper presents an improved design method for three types of wind-induced vibration control of high-rise buildings (cables, wind deflectors and adjustable mass dampers). In this paper, a pulsating wind shaping filter is established, and the control law of the extended quadratic objective function based on the structural layer displacement, velocity, and acceleration response is derived, and the control requirements for high-rise building strength, stiffness, and comfort are achieved. The specific design method of passive control employs a simple and practical adaptive control method to achieve active control.
