［摘要］台北艺术中心由中心的方形量体及周边外延的3个剧场组成，体型十分复杂且不规则。由于工程地处高地震烈度区，抗震性能要求很高。经比较研究，采用基础隔震系统被认定为经济技术上最为优化的方案。设计中重点解决了上部结构的抗侧及抗扭刚度、隔震器类型及参数选择等问题。基础隔震系统可将结构所受地震作用及构件位移控制在可接受的范围，并具有高度的可靠性；相较传统抗震方法，基础隔震方案可减小地震作用达60%以上；与其他类型的隔震器相比，所用摩擦单摆型隔震器具有更好的经济性及更简化的细部处理。

Abstract:The Taipei Performing Arts Center  consists of a central cube and three theatres that plug into the central cube. The body shape is very complex and irregular. The structure is located in the high seismic intensity area with high seismic performance requirements. The base isolated system was adopted as the optimum economic and technical solution through analyses and comparisons. The lateral and the torsional stiffness of the superstructure, the selection of the isolator type and parameters were determined in design. The base isolated system enabled to control the seismic forces and displacements of the members to acceptable levels with a high degree of  reliability. Seismic action of the base isolation scheme were reduced by over 60% compared to a conventional seismic solution. The friction pendulum type isolator was chosen since they delivered a better performance than other types in economy and simpler details.
