碩士 === 國立臺灣大學 === 機械工程學研究所 === 103 === This thesis investigates the performance benefits of building suspension systems employing the inerter. The inerter was proposed as a genuine two-terminal mechanical device to substitute for the mass element to improve performance of mechanical systems. The invention of inerters bridges the gap between the mechanical and electrical systems. So far, the inerter has been successfully applied to vehicles, motorcycles, trains, and proven to enhance its performance benefits. This thesis focuses on the following three topics: one-layer, two-layers, and multi-layers building models. First, we apply three inerter layouts and four historical earthquake data to a one-DOF building model to illustrate how inerter can improve its suspension performance. The simulation results demonstrated the effectiveness of inerters in suppressing earthquake vibrations. Second, we extended the discussion to a two-layer building system. In addtion, we used weighting performance index to analyze the performance benefits between two layers. Last, we build a multi-layers building structure and discussed the numbers and location of inerters for building performance benefits. Furthermore, we analyzed the connected suspension of adjacent building systems, and applied the inerter layouts to the concerned suspensions of adjacent buildings. For experimental verification, we applied the Similitude Law to design scale-down building models and discussed the improvment of the earthquake vibration by inerters. We also built SimMechanics models for comparison with the experimental results. In addition, we discussed the inerter in vertical and diagonal support for suppressing building vibrations.
