摘要: | 近年来,有关结构减震消能元件的研发与实务应用已有具体成果,相关之设计方法与法规亦陆续修订完成。本文提出黏滞消能结构之最佳设计法,可由位移或加速度反应效能指标之最小化,决定线性液流阻尼器之最有效配置方式。本法适用于线性液流阻尼器安装于所有楼层或部分楼层之情况。此外,凡扰动频谱为已知者,亦可一并纳入最佳化设计之控制因素中。经由理论推导、数值验证与实例分析,证明利用本研究之最佳化设计法所设计之迟滞消能结构具良好之控制效果,相较于依据NEHRP规范所设计者效益更高。 In recent years, advances in the development and practical implementation of energy dissipation devices for earthquake protection of structures have been achieved. Design methods and code specifications in this regard have been devised as a consequence. This thesis proposes an optimal design method for structures implemented with supplemental viscous dampers. The most efficient arrangement of linear fluid dampers may be determined from minimizing the displacement or acceleration response index defined. The proposed optimal design method allows for consideration of placing linear fluid dampers at full or partial floors of the building. Moreover, the given design spectrum of the excitation may be taken into account in the optimization process if desired. Effectiveness of response control based on the proposed optimal design method has been verified via theoretical development and numerical simulations. It has been shown to be more efficient than those designed in accordance with NEHRP provisions. |
