摘要

國內在921地震後，特別重視現存建築物的耐震能力，尤其老舊建築物更是急需作耐震能力的評估。現今國內工程界大多以內政部建築研究所於1999年公佈的「鋼筋混凝土建築物耐震能力評估法與推廣」為建築物耐震評估的依據。但是隨著世界的潮流，台灣的建築結構物的功能與型態愈趨於複雜，若單只求建築物於地震中不發生倒塌，已經不符合國內現今建築物的需求了，因此本文利用美國ATC-40耐震性能評估法的觀念，對結構物進行非線性靜力分析，並引用內政部建築研究所於921地震後修訂的設計反應譜取代ATC-40中的設計反應譜，以期能夠真實的反應建築物於地震中的反應，並以層間變位角與桿件韌性的限制求取其對應的崩塌地表加速度以方便與現行耐震評估法比較。文中以兩棟現存建築物為例，比較與探討兩種評估方法的結果及原因。

People paid much attention on the seismic capacity of buildings after the Chi-Chi earthquake happened. The 1999 year edition of “the Seismic Capacity Assessment for RC Building”, promoted by “Architecture & Building Research Institute, Minster of Interior”, was the most popular in Taiwan. By the trend of the world, the buildings with different functions are getting more complex in structural systems. The minimum requirement for buildings to not collapsed during the earthquake, won’t meet the demand of buildings nowadays. Thus this thesis use of the concept of ATC-40 performance-based earthquake assessment from America to proceed nonlinear statics analysis for buildings besides the design spectrum is the Taiwan’s data which can really responded the reaction of structures during Taiwan earthquakes. The story drift ratio and ductility of members are justified in the corresponding collapse ground acceleration and compared with the current method of seismic evaluation. Furthermore this study compared and discussed the results of the two methods with two existing buildings.
