This study presents an advanced experimental system, hardware‐in‐the‐loop (HIL), recently referred to as hybrid testing, to validate the effectiveness of a double‐decker tuned sloshing damper (TSD) system with screens applied to a recently constructed tall building. The HIL simulation facilitates a performance analysis of a combined structure‐damper system in which the nonlinear behavior of liquid motion in a TSD is physically modeled, whereas a building system under wind loads that behaves linearly is embedded virtually utilizing a computer model. The scaled model of the TSD is composed of a computer‐controlled system with a shaking table, sensors, and a real‐time communication link. The virtual building system on the computer communicates in real time with the hardware, that is, the physical model of TSD to evaluate on‐the‐fly the performance of a combined building‐TSD system. External excitation including random loading characteristics of winds, waves, or earthquakes can be implemented in HIL to observe the dynamics of the building‐damper system under a host of loading scenarios. An example of a recently completed tall reinforced concrete building with multiple TSDs placed side by side in double‐decker configuration under a suite of external loads and the proposed damping estimation procedure to evaluate the amount of auxiliary damping with TSD for ensuring the TSD design is presented. It examines the habitability of the building in winds and evaluates the effectiveness of the TSD system as well as the efficacy of the first HIL simulation for an actual tall building‐TSD system equipped with screens inside.

风荷载下带有双层调谐减振系统的高层建筑的混合仿真

这项研究提出了一种先进的实验系统，硬件在环（HIL），最近称为混合测试，以验证双层筛调谐防振阻尼器（TSD）系统的有效性，该系统将筛网应用于最近建造的高层建筑建造。HIL仿真有助于对组合结构阻尼器系统的性能进行分析，在该系统中，对TSD中液体运动的非线性行为进行了物理建模，而在风荷载下具有线性行为的建筑系统实际上是通过计算机模型嵌入的。TSD的比例模型由带有振动台，传感器和实时通信链接的计算机控制系统组成。计算机上的虚拟建筑系统与硬件进行实时通信，即，TSD的物理模型，以动态评估组合式建筑TSD系统的性能。可以在HIL中实现外部激励，包括风，浪或地震的随机加载特性，以观察多种负载情况下建筑阻尼器系统的动态。介绍了一个最近完成的高层钢筋混凝土建筑的示例，该建筑在多个外部荷载下以双层结构并排放置了多个TSD，并提出了用于通过TSD评估辅助阻尼量以确保TSD设计的阻尼估计程序。 。它检查了建筑物在风中的可居住性，并评估了TSD系统的有效性以及首次在内部装有屏幕的高层TSD系统进行HIL模拟的有效性。
