斜拉弹簧质量阻尼器的风振控制机理

Mechanism of Wind Vibration Gontrolby Cross-tensioned Spring Mass Dampers

本文针对斜拉弹簧质量阻尼器（ＴＳＤ）对结构风振控制机理作了深入分析。文中指出ＴＳＤ实际上是一种非线性控制装置，并在豚动风模拟基础上，给出非线性ＴＳＤ作用下结构的受控反应的求解方法。另外在ＴＳＤ满足一定的构造条件下，可忽略ＴＳＤ的非线性，从而可用线性随机振动理论求解结构的受控反应，因此可大大简化ＴＳＤ的设计计算。上上两种分析方法均考虑了斜拉弹簧对结构风振控制的影响。

The mechanism of wind vibration control of structures using cross-tensioned spring mass dampers (called TSD for short) has been deepened in analysus. lt is pointed out that TSD is a nonlinear control device, and the method of solving oontrolled response of structures with TSD are given in this paper on the basis of pulsating wind simulation. However, the nonlinearity of TSD can be neglected in case it meets a certain configuration condition and the controlled response of structures can be solved by linear random vibration method. This method simplifies the calcula- tion. Both of the above-metioned two methods have taken into consideration the effects of TSD on the wind vibration control of the structure .
