自立式高耸结构风振控制方法研究

本文针对自立式高耸结构的风振控制装置及其设计方法开展研究。首先，根据自立式高耸结构的特点，设计了环形TMD、TLD和TLCD三种调频减振装置，并推导了其力学模型；随后，基于等效阻尼比的概念和我国规范的抗风设计方法，建立了自立式高耸结构风振控制的统一设计方法；最后，针对数值算例，进行了风振控制装置设计，并通过时程分析方法验证了该方法的有效性。研究结果表明，所设计的三种环形调频减振装置适用于自立式高耸结构的风振控制，建立的简化设计方法与时程分析的结果平均误差仅为5.37%，具有较高的精度，可用于自立式高耸结构的风振控制设计。

Investigation on Techniques for Wind-induced Vibration Control of of Self-standing High-rise Structures

In this paper, the damping devices and their design methods for self-standing high-rise structures under wind loads are studied. Firstly,according to the characteristics of self-standing high-rise structures, three tuned frequency damping devices (Ring shape tuned mass damper, Ring shape tuned liquid damper and Ring shape tuned liquid column damper) are designed, and their mechanical model are deduced in the paper. Secondly, on the basis of the equivalent damping concept and the wind resistance design methods in China codes, the unified design methods of these damping devices for self-standing high-rise structures are established. Lastly, the wind-induced vibration control designation of two numerical expamples is presented using the proposed design method, whose effectiveness is confirmed by time history analysis method at the same time. The study shows that, the three ring shape damping devices designed in this paper are applicable to the vibration control of self-standing high-rise structures, and the analyze results show that the mean relative error between the results using equivalent damping method and time history analysis method is only 5.37%, so the proposed design method has a high precision, and can be used for the vibration control designation of self-standing high-rise structure under wind loads.

Secondly, on the basis of the equivalent damping concept and the wind resistance design methods in China codes, the unified design methods of these damping devices for self-standing high-rise structures are established. Lastly, the wind-induced vibration control designation of two numerical expamples is presented using the proposed design method, whose effectiveness is confirmed by time history analysis method at the same time. The study shows that, the three ring shape damping devices designed in this paper are applicable to the vibration control of self-standing high-rise structures, and the analyze results show that the mean relative error between the results using equivalent damping method and time history analysis method is only 5.37%, so the proposed design method has a high precision, and can be used for the vibration control designation of self-standing high-rise structure under wind loads.
