摘　　要：为进一步改善和提高该建筑居住者的舒适性,根据实际建筑的结构动力特性调谐液体阻尼器对TLD进行设计使其与建筑结构同频反向振动从而达到振动控制的目的,采用水箱内格栅结构以及水体与水箱壁的摩擦碰撞进行耗能。原设计方案为两个TLD水箱,受屋顶直升机停机坪结构影响,优化为一个TLD水箱,同时对TLD相应技术参数予以调整,不仅满足结构消防储水的要求,也实现了对结构舒适度的控制。In order to further improve and enhance the comfort of the occupants of this building,according to the dynamic characteristics of the actual building structure,the TLD damper is designed to make it vibrate in reverse with the same frequency as the building structure so as to achieve the purpose of vibration control.The grid structure in the tank and the friction collision between the water body and the tank wall are used for energy dissipation.The original design scheme is two TLD water tanks,which is optimized into one TLD water tank due to the influence of the roof helipad structure.At the same time,the corresponding technical parameters of the TLD are adjusted,which not only meets the requirements of the structural fire water storage,but also realizes the control of the structural comfort level.
