摘要:	本研究主要對於柱箍筋間距過大，未符合強柱弱梁，及梁柱接頭未配置箍筋，或箍筋量不足之非韌性鋼筋混凝土建築物，評估其耐震能力，對於耐震性能有疑慮之既有建築物及早進行補強的工作，並說明擴柱補強設計原則，期能提供一實用之補強工法。本文先舉實際案例，以現行國內及紐西蘭評估法，對於鋼筋混凝土建築物耐震能力之評估分別作探討，並比較其結果；後再以一雙層兩跨之鋼筋混凝土非韌性構架作反覆載重之耐震測試，後對受損之構架，以鋼筋混凝土擴柱補強後再行測試，比較測試與評估結果，並印證補強之成效；結果顯示，擴柱補強有效改善原有之結構行為。 This study was aimed at assessing the seismic behavior of the existing non-ductile reinforcement concrete buildings with substandard deficiencies in columns and beam-column joints. The designed principle of concrete jacketing scheme was also described. An existing building was selected for seismic assessment by means of guidelines from Taiwan and New Zealand. Main conclusion will be made on the assessment results of two guidelines. Meanwhile, a two story-two bay reinforced concrete moment-resisting frame had been tested under cycle loading to specially verify the failure mode predicted by New Zealand method. The test result also showed that overall seismic performance could be improved due to the 150 mm thick concrete jacket applied to columns and beam-column joints.
