An innovative hybrid vibration controller (HVC) composed of unbonded fiber-reinforced elastomeric isolators (UFREIs) and tuned mass dampers (TMDs) is utilized for the vibration control of an existing hospital building under the multi-hazard scenario of earthquakes and (nonconcurrent) winds. A 3-dimensional nonlinear model of the considered hospital building is analyzed. Four configurations of the HVC are investigated, wherein single or multiple TMDs are utilized, having various tuning properties and locations along the height of the building. All the various controlled and uncontrolled structures are subjected to site-specific bidirectional earthquake and wind excitations. Results reveal that the HVC with two TMDs, having favorable tuning conditions for both earthquakes and winds, are the most efficient under the multi-hazard scenario. Interestingly, the increase in the TMD mass ratio always improves the performance of the HVC under wind excitations, however under earthquakes, it may also result in enhanced deterioration of HVC performance in detuned conditions.

具有单调谐质量阻尼器和多调谐质量阻尼器的 UFREI 隔震结构在地震和风作用下的双向性能评估

由非粘合纤维增强弹性体隔振器 (UFREI) 和调谐质量阻尼器 (TMD) 组成的创新混合振动控制器 (HVC) 用于在地震和（非并发）风的多重灾害情况下控制现有医院建筑的振动。对所考虑的医院建筑的 3 维非线性模型进行了分析。研究了 HVC 的四种配置，其中使用单个或多个 TMD，它们具有不同的调谐特性和沿建筑物高度的位置。所有各种受控和非受控结构都受到特定地点的双向地震和风激励。结果表明，具有两个 TMD 的 HVC 对地震和风都有有利的调节条件，在多种灾害情况下是最有效的。有趣的是，TMD质量比的增加总是会提高HVC在风激励下的性能，然而在地震下，它也可能导致HVC在失谐条件下的性能恶化。
