中文摘要: 本研究目的為建立鹽害與中性化影響之RC校舍耐震能力評估法。
利用鋼筋混凝土劣化預測模式與外觀目視劣化度判定,評估柱構件之
鋼筋腐蝕量,並對腐蝕柱構件其塑鉸性質進行折減,結合國震中心之
耐震能力評估輔助程式,評估劣化RC 校舍之耐震能力。另外,本研
究以台灣中小學震損RC 校舍建築為標的,依日本現行診斷方式判定
柱構件損傷度,結合國震中心之耐震能力評估輔助程式以評估其耐震
能力,最後再依照日本建築防災協會所制定之耐震性能殘率,給予其
建築物震損程度之判定。綜合上述,本研究建立之耐震能力評估法可
考慮「劣化」與「震損」兩種現象對於RC 校舍耐震能力之影響,可
提供工程師考慮此兩種現象並實行耐震能力評估之參考。
英文摘要: The purpose of this study is to establish the seismic performance evaluation method for chloride-induced and carbonation-induced deteriorating reinforced concrete (RC) school buildings. The method uses the deterioration prediction model of reinforced concrete and the appearance of deterioration degree to estimate the corrosion of RC columns and then simulates the reduction factors for the hinge properties of corroded RC columns. For practical convenience, this proposed method has been combined with the seismic performance evaluation method developed by National Center for Research on Earthquake Engineering in Taiwan (NCREE) to evaluate deteriorating RC school buildings’ seismic performance. In addition, the authors also propose the seismic performance evaluation method for earthquake-damaged RC school buildings in this study. According to the seismic damage state of RC columns and their corresponding strength reduction factors, suggested by Japan Building Disaster Prevention Association, the authors use the seismic performance evaluation method developed by NCREE to evaluate the earthquake-damaged RC buildings’ seismic performance. Above all, the seismic performance evaluation procedure proposed by this study can consider the effect induced by "deterioration" or "seismic damage " on the seismic performance of RC school buildings.
