高层建筑几种风振控制方式的设计方法

Design Method of Some Wind Vibration Control Mechanisms of Tall Buildings

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 to three kinds of wind vibration control mechanisms of tall buildings which are the guy wires, windshields and tuned mass dampers, In this paper, the filter of fluctuating wind force is established; the governing law of the objective function with extended quadratic forms based on story drifts, velocities and accelerations of structural is derived, thus satisfying the requirements for strength, stiffness and comfort of tall buildings, a design method of passive control is presented and finally a simple and practical auto-adaptation control method is applied, by which the active control is actually achieved.
