經過歷年地震災損經驗，台灣已逐漸重視圖書館內部書架之耐震性能。雖多數圖書館建築結構於地震中未受重大破壞，惟書架倒塌或損壞常導致館藏書籍受損、圖書館功能中斷，對於使用者亦可能構成人身危害且災後修復亦需耗費大量人力與財政資源。有鑑於此，本研究蒐集國內常見圖書館書架型式與耐震補強工法(如頂部繫緊支架、地板錨定)，並透過國家地震工程研究中心（NCREE）振動台進行實驗，以驗證其耐震效能並建立對應之數值模型，以模擬不同補強配置下之動態反應，進一步提出具體可行之耐震設計建議。從實驗結果與數值模擬綜合比較，將書架底部錨定並提升書架結構剛度，能有效降低頂部加速度約60%，然而僅裝設繫緊支架的補強方式無法對書架頂部加速度有效降低。此外，考量圖書大量掉落對於人員安全與後續修復作業所造成之衝擊，本研究亦同步評估書籍防墜的設計，期能整合構件與內容物防護。經實驗發現當書架X方向受到超過728gal的加速度時書本開始有機率落下，然而增設書本防墜鋼索後書本掉落的臨界加速度提升到1695gal，大幅提升整體書架系統於地震情境下之安全性與功能維持能力。

Drawing on earthquake loss experience in Taiwan, this study examines the seismic performance of library shelving. We catalog common shelf types and retrofit schemes (e.g., top tie braces, floor anchorage), conduct full-scale shaking-table tests at the National Center for Research on Earthquake Engineering (NCREE), and build numerical models to simulate alternative configurations and derive practical design guidance for implementation. Results show that floor anchorage combined with increased stiffness reduces peak top-shelf acceleration by ~60%, whereas tie braces alone do not effectively suppress it. Considering life-safety and recovery impacts from book fallout, we also evaluate content-protection measures. Experiments showed that books began to fall at 728 gal in the X-direction, but with anti-fall cables, the critical acceleration increased to 1695 gal, greatly improving the bookshelf’s seismic safety and stability.
