THE INFLUENCE FACTORS ON THE STRENGTH AND DUCTILITY OF THE REINFORCED CONCRETE COLUMNS EXTERNALLY BONDED WITH CFRP

摘要: 基于2 3根外贴碳纤维布(CFRP)钢筋混凝土偏压柱及对比柱在单调荷载作用下的试验结果,比较分析了在其他条件相同的情况下CFRP粘贴方式、混凝土强度、柱纵向配筋率和荷载偏心值这4个因素对柱的承载力和延性的影响,得出了对外贴碳纤维布加固钢筋混凝土偏压柱有重要意义的结论。

Abstract: Basing on the experiment of 23 prototype reinforced concrete columns under eccentric simple-loaded action,four influence factors on the strength capacity and ductility of the columns have been studied respectively,which are the CFRP bond manner,load eccentricity,concrete strength and the longitudinal reinforcement ratio of columns.The research is significant to the strengthening of the RC columns with CFRP sheets. -
