摘要

鋼骨鋼筋混凝土構材為一種結合鋼骨及鋼筋混凝土之複合構材，其具有兩者之優點，且能避開這兩種構材的缺點。因此鋼骨鋼筋混凝土構材已漸為目前建築結構最常用之建築構材之一，且其耐震特性也是從事鋼骨鋼筋混凝土結構設計者相當關心之課題。本研究首先探討模擬鋼骨鋼筋混凝土構件線性及非線性行為之方法，並將模擬之結果與實際鋼骨鋼筋混凝土構件試驗數據比較以證明此模擬方式之可行性。本文又以實際鋼骨鋼筋混凝土結構為案例，以FEMA 273所建議之耐震性能評估法對鋼骨鋼筋混凝土結構進行非線性靜力之推覆分析，並探討其耐震能力，另採用實際紀錄之地震資料進行非線性動力歷時分析，並將兩種方法互相比較。經由分析比較之結果，鋼骨鋼筋混凝土結構之耐震能力高於依照目前耐震設計規範設計所預估者，且推覆法分析相較於歷時分析為一保守且有效率之耐震性能評估方法。

The steel reinforced concrete (SRC) member is a composite of steel member and reinforced concrete.Not only does it has the advantages of steel and reinforced concrete both , but it can avoid their shortcomings.Therefore , of the construction at present , the SRC member has already become the most common member gradually , and the engineers designing SRC buildings are vary concerned about the characteristics of SRC structure when SRC structure is subjected to earthquake.In this thesis ,we propose a method of simulating SRC member’s linear and nonlinear behavior first, and we compare the result of simulating with the experimental data of actual SRC member to prove the accuracy of simulating. Finally taking actual SRC structure for example , we analyze the two cases based performance-based assessment of FEMA 273 with nonlinear static procedure (pushover analysis) and nonlinear dynamic procedure. According to the results of analysis , we find that SRC structure can bear higher earthquake level than we estimate the earthquake level which the SRC structure can bear according to the code at present , and pushover analysis is a conservative and efficient seismic evaluation of performance-based method.
