摘要
本研究主要在評估早期興建低矮鋼筋混凝土建築之耐震行為，以一雙層兩跨試體來模擬測試，其梁柱接頭未配置箍筋，柱箍筋間距30公分，為一典型之非韌性構架，測試的方式使用反覆加載模式，於試體受損後以鋼筋混凝土擴柱修復，再行測試，探討補強之成效。
實驗結果顯示，原型試體之破壞模式為強梁弱柱及梁柱接頭損壞
而以鋼筋混凝土擴柱包覆修復對試體初始勁度，試體承受側向力之強度，梁柱接頭抵抗剪力變形之能力均有良好之成效，另外修復後的試體之破壞模式與原試體NF非韌性破壞不同，為梁塑鉸區破壞，顯示混凝土擴柱補強能有效改變原有破壞模式。

Test on the Seismic Performance of Two Story-Two Bay Reinforced Concrete Moment Resisting Frame
Abstract
This study was mostly aimed at assessing the seismic behavior of the existing 2 story-2 bay reinforced concrete building frame.The selected moment-resisting frame which has the characteristics of the lack of transverse reinforcement in the beam-column joint and the 30cm interval of transverse reinforcement in the column was a typical non-ductile frame.After the frame has been damaged under cycle loading, Concrete Jacketing will be applied to the rehabilitation of the frame.A discussion is made between benchmark and retrofitted specimen.
Test results showed that the benchmark specimen behaved as a typical non-ductile frame and the retrofitted frame represented a better performance in initial stiffeness , the capacity of resisting lateral force ,and the shear strength of beam-column joints.
