摘要
为研究竖向钢筋套筒浆锚连接的预制柱的力学性能,完成了6个柱试件的拟静力试验,其中2个为现浇试件.试验结果表明:套筒浆锚连接能够有效传递竖向钢筋的应力;预制柱的破坏形态与现浇柱基本一致,为拉区混凝土开裂、竖向钢筋受拉屈服、压区混凝土压碎的受弯破坏;预制柱试件的刚度和耗能能力与现浇墙试件相当,极限位移角达1/1219~1/49.
To study the mechanical behavior of pre - cast reinforced concrete columns with vertical rein- forcements spliced by grout sleeves quasi -static tests of 6 column specimens, among which there are two rein- forced concrete columns. The test results indicate that the stresses of the vertical reinforcements can be trans- ferred effectively by grout sleeves. The failure mode of the pre - cast specimens is almost the same as that of the east - in - place specimens. The stiffness and the energy dissipation capacity of the pre - cast column specimens are similar to those of the cast - in - site column specimens. The ultimate drift ratios of the pre - cast wall speci- mens are 1/1219 -1/49.
