摘　　要：介绍了4个JGN,RE500结构胶植筋混凝土柱在水平反复荷载作用下的试验现象及结果,并与非植 筋柱进行了比较,探讨了锚固长度、焊接等因素对植筋混凝土柱延性和耗能能力的影响。结果表明,实测轴压 比0.3、锚固长度15d以上的焊接(焊接高度10d)、非焊接植筋混凝土柱具有良好的延性和耗能能力。Experimental results of RC columns with postinstalled chemically longitudinal rebars with JGN,RE500 structure glue under cycle reversed horizontal load are presented,and compared with that of a cast-in-place column.Influences of embedded length and welding on ductility and energy-absorbing capability of RC columns with postinstalled chemically rebars are discussed. The welded(welding height is 10d)and non-welded RC columns whose embedded depth is 15d have good ductility and energy-absorbing ability when their axial compression ratio are 0 3.
