Viscous dampers (VDs) connecting adjacent multi-story buildings are significantly useful not only for preventing severe earthquake-induced pounding, but also for mitigating the response of buildings. In the current study, in addition to utilizing viscous dampers, enhanced hybrid active tuned mass dampers (EHATMDs) are used at the top of asymmetric buildings and active tendons (ATs) are used at the sixth floor of symmetric buildings, while all these buildings are interconnected by VDs. The interval type-2 fuzzy logic controller (IT2FLC) is employed to produce real-time active forces applied to the actuators of EHATMDs and ATs. Moreover, soil-structure interaction (SSI) effects are considered. The aim is to assess the performance of all the mentioned controllers in mitigating both the translational and torsional responses of structures rested on soft soil. To reach these goals, three different layouts of adjacent buildings, including asymmetric and symmetric buildings, are taken into account. The results showed that the layout where asymmetric buildings were controlled by VDs in both main directions had the highest performance.

考虑土壤-结构相互作用的2型模糊控制器的粘性阻尼器互连的相邻建筑物的混合主动控制

连接相邻多层建筑物的粘性阻尼器(VD)不仅可用于防止严重的地震引起的撞击,而且还可用于缓解建筑物的响应。在当前的研究中,除了利用粘性阻尼器之外,非对称建筑物的顶部还使用了增强型混合动力主动调谐质量阻尼器(EHATMD),对称建筑物的第六层使用了主动筋(AT),而所有这些建筑物都是通过VD互连。区间2型模糊逻辑控制器(IT2FLC)用于产生施加到EHATMD和AT的执行器的实时作用力。此外,考虑了土壤-结构相互作用(SSI)的影响。目的是评估所有提及的控制器在减轻软土地基上结构的平移和扭转响应方面的性能。为了实现这些目标,考虑了相邻建筑物的三种不同布局,包括不对称和对称建筑物。结果表明,非对称建筑物在两个主要方向上受VD控制的布局具有最高的性能。
