    Abstract: 民國88年9月21日台灣發生芮氏規模7.3的強烈地震,突顯出台灣在建築體系上的許多問題。從統計數字資料發現,此次地震以鋼筋混凝土建築物受損最為嚴重,其中一樓因開放空間所造成的軟弱層及構架中因窗台設計所填充之非結構磚牆而造成的短柱效應等等原因,都可能造成建築物在地震中遭受損傷。本文就以在此次地震中受損之社區-大里奇蹟社區作為一研究主題,以學術研究之觀點,來探討其倒塌原因。 首先,本文以ETABS程式進行結構動力分析,並配合CONKER程式進行結構韌性設計,檢核原結構在斷面與配筋上是否符合現行耐震設計規範之標準。接著,為探討建築物進入降伏後之非線性行為,本文以SAP2000電腦輔助程式建構其模型,並利用ATC-40所提供的推倒方法,來進行結構之非線性分析。藉由結構之破壞機制及所能承受之最大基底剪力與最大位移來評估此建築物之耐震能力。 An earthquake with a magnitude of 7.3 occurred on 21 September 1999 which induced many problems of architectural system in Taiwan. From statistical data, we can found that the R.C. buildings were damaged seriously. The open space in first floor will cause weak layer. The non-structural brick wall because of design of window will cause short-column effect. As a whole, these reasons may induced the buildings damaged during this earthquake. This study uses the case of ‘community in Ta-Li Miracle’ which was damaged seriously in 921 earthquake in order to find out the reasons of collapse. First, the study progress structural dynamic analysis by ETABS program and progress structural design by CONKER program. The purpose is to check whether the cross section conform to the request of design code. Second, For discussing the building’s nonlinear behavior after yielding, the study builds the module by SAP2000 program and uses the Pushover method which is provided by ATC-40 to progress the nonlinear analysis. By structural failure mechanism and the structural utmost base shear and displacement, we can evaluate the building’s capacity of resistant earthquake.
