［摘要］臺北藝術中心由中心的方形量體及周邊外延的3個劇場組成，體型十分復雜且不規(guī)則。由于工程地處高地震烈度區(qū)，抗震性能要求很高。經(jīng)比較研究，采用基礎隔震系統(tǒng)被認定為經(jīng)濟技術上最為優(yōu)化的方案。設計中重點解決了上部結構的抗側及抗扭剛度、隔震器類型及參數(shù)選擇等問題。基礎隔震系統(tǒng)可將結構所受地震作用及構件位移控制在可接受的范圍，并具有高度的可靠性；相較傳統(tǒng)抗震方法，基礎隔震方案可減小地震作用達60%以上；與其他類型的隔震器相比，所用摩擦單擺型隔震器具有更好的經(jīng)濟性及更簡化的細部處理。

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.
