摘要

台灣目前的建築物耐震設計實務中，多未將非結構物納入耐震設計考量，所以當遭遇規模較大的地震時，便可能會發生因為非結構物的損壞致使醫院的緊急醫療能力中斷之窘境。本研究以問卷方式至現場調查921集集地震之受災醫院內非結構物的損壞情形，並以非結構物之易損性曲線來檢視損壞程度與發生機率之關係。經分析問卷調查表內各項非結構物的損壞情形後，將之分為輕度、中度、重度損壞以進行損壞比率分析。最後提供三類共26項非結構物的易損性曲線，作為國內爾後相關應用之參考。

Building code requires hospitals to be the type I building in order to raise the seismic-resistant capacity of hospital building in Taiwan. But nonstructural components were never taken into account in the design in general. Hence, the damage of nonstructural components resulting in interruption of emergency medical care can happen when hospitals experience a larger seismic intensity scale. In this study, the authors investigated hospital buildings in the Chi-Chi earthquake with damaged nonstructural components by means of questionnaire, and examined the relationship between damage levels and probability expressed with fragility curves. After classifying damage states of each nonstructural component listed in questionnaire sheets into minor, moderate, and severe damage level, component damage ratios were computed. Finally, fragility curves for 26 nonstructure items grouped in 3 categories are developed for future applications.
