日本POLA艺术博物馆的隔震结构和玻璃天窗

本文具体介绍了建造在自然环境中的POLA艺术博物馆的结构设计概要。为了满足艺术珍藏品在地震时不至损坏的博物馆特有的技术要求,保护地震时人命安全,结构设计时对这座几乎建造于地下的建筑采用了基底隔震系统,而且在上部结构的底部采用了立体大跨度桁架系统,更有效合理地实现了基底隔震系统的隔震性能。隔震系统和大跨度桁架系统的结合统一,既实现了优美的建筑设计要求,又确保了结构在大地震下的高度抗震性能。

Glass Skylight and Structure for the POLA Museum of Art in Japan

Located within a national park,the POLA Museum of Art has been constructed with almost all of the buildings placed underground.To protect the people and artworks from earthquake damage,a base isolation system has been used.A basin-shaped structure has been used for the base structure to enable it to effectively resist earth and water pressure.The upper structure is cross-shaped in plan,with a section shape that shrinks downward to match the base structure.The upper structure has double-crossed main trusses and sub trusses,providing high safety and stability in the case of earthquake.So these trusses and base isolation system make it possible to create an atrium environment with light filtering down, highly transparent glass skylight,and cross-shaped steel columns.
