Abstract:	本文目的為探討應用容量震譜法，評估結構不規則低層鋼筋混凝土樓房耐震能力之可行性，並使用非線性動態歷時分析法，來計算結構物之地震反應行為，作為兩者比較之基準。分析時，分別採用ATC-40所建議之參數組於推垮分析，與EUROCODE 8 之經驗公式於非線性動態歷時分析中，模擬鋼筋混凝土梁、柱之非線性行為。文中採用三組不同特性之地震歷時記錄，作為輸入歷時反應。以一棟位於中央大學校內，平面及立面皆不對稱之鋼筋混凝土建築物為案例，進行數值分析比較，期能暸解容量震譜法與非線性動態歷時分析法，用於評估不規則低層鋼筋混凝土結構耐震能力之差異程度。研究結果證明，容量譜震法於評估結構不規則低層鋼筋混凝土樓房之耐震能力其結果可以接受。 The objective of the present study is to investigate the feasibility of applying the capacity spectrum method to assess the seismic capability of the low-rise, RC building of irregularities. The nonlinear time history responses of the RC building to ground motions are used as basis for justification. The parameters suggested by ATC-40 are adopted in the method of pushover and the formulas suggested by EUROCODE 8 are used in the time history response analysis respectively to simulate the nonlinear characteristics of RC beams and columns. In addition, three sets of earthquake time history records are used as excitations in nonlinear time history response analysis. A low-rise RC building on campus of the National Central University is analyzed numerically to understand the differences between the results of the above mentioned methods. It is found that the results of seismic assessment by using the capacity spectrum method for the low-rise, RC building of irregularities will be acceptable.
