[论文][Paper] 深圳某400m双塔连体结构TLD风振控制可行性研究 (Feasibility investigation of wind-induced vibration control using TLD for a 400-meter twin-tower connected structure in Shenzhen)

实干、实践、积累、思考、创新。

Mark一下！这是一篇关于采用调谐液体阻尼器 (TLD) 对高层建筑结构进行风振舒适度控制的文章。论文以深圳湾超级总部基地C塔项目为背景，系统梳理了该结构在特殊风环境下的动力响应特征，并对TLD控制系统应用于此类复杂连体结构的可行性进行了探讨。同时，我们也结合项目实际需求，提出了方案阶段可实施的水箱阻尼器初步设计建议。

本研究的初步工作源于三年前在廖耘总带领下的团队工作成果，是我们参与C塔项目顾问期间所完成的一系列振动控制专项分析的汇总，也算是我们在结构减振领域的一次探索。论文三年前已经录用了，现在才刊登出来。现在回望，当时对这块内容的理解还不够深刻，诸多细节仍有进一步完善的空间。但也正因如此，它真实记录了我们从实践中学习的历程。谨借此文，抛砖引玉，期待与更多同行交流探讨，共同推动结构振动控制技术的发展。

【中文摘要】	深圳某400m双塔连体项目结构体系为带伸臂、环桁架加强层的框架-核心筒双塔连体结构，包含东、西两座塔楼及连接体。受复杂建筑造型、较大风荷载及特殊场地风环境影响，在10年一遇风荷载作用下，塔楼于东南风来流方向呈现显著的动力响应，塔楼顶部风振加速度远超规范限值，导致舒适度不足。为解决此问题，拟采用调谐液体阻尼器(TLD)对塔楼进行风振控制。通过频谱分析识别结构风致响应的控制振型，并采用时程法对设置TLD结构进行风时程动力响应分析，结合敏感性分析获得最优TLD设计参数。结果表明：结构基底剪力及东塔顶部风振加速度频谱呈单峰特性，主要受东塔一阶平动振型控制；西塔顶部风振加速度频谱则呈双峰特性，同时受东、西塔一阶平动振型影响。在东塔顶部设置TLD可显著降低结构基底剪力及东、西塔的顶部风振加速度；而西塔顶部设置TLD仅能有效降低西塔垂直连接体方向的顶部风振加速度，对其沿连接体方向及东塔顶部的风振加速度和结构基底剪力均无明显控制效果。东、西塔顶部同时设置TLD后，塔楼的顶部风振加速度得到有效控制，满足规范限值要求。
【Abstract】	The structural system of a 400m twin-tower linked project in Shenzhen features a frame-core tube configuration with outriggers and belt truss strengthening story, comprising eastern and western towers connected by connective structure. Due to complex architectural geometry, high wind loads, and unique site-specific wind conditions, under 10-year return period wind loads from the southeastern direction, the towers exhibit significant dynamic responses. Wind-induced accelerations at the tower tops substantially exceed code limits, resulting in occupant comfort deficiencies. To address this, tuned liquid dampers (TLDs) were proposed for wind vibration control. Spectrum analysis was employed to identify governing vibration modes of structural wind-induced responses. Time-history analysis was conducted to evaluate wind-induced dynamic responses of the TLDs-equipped structure, with parametric sensitivity analysis subsequently optimizing TLD design parameters. The results demonstrate that the structural base shear and the wind-induced acceleration spectrum at the eastern tower top exhibit a single-peak characteristic, primarily governed by the first translational mode of the eastern tower. The wind-induced acceleration spectrum at the top of the western tower shows a double-peak characteristic, influenced concurrently by the first translational modes of both the eastern and western towers. TLDs installed atop the eastern tower significantly reduce base shear and wind-induced accelerations at both tower tops. However, TLDs at the top of the western tower only effectively mitigate accelerations perpendicular to the connective structure but show no significant control effect on accelerations along the connective structure direction, the accelerations at the top of the eastern tower, or the structural base shear. Furthermore, when TLDs are installed simultaneously at the tops of both towers, wind-induced accelerations are effectively controlled, ensuring compliance with code-specified limits.
