高强钢筋高强混凝土粘结锚固性能研究

摘要

对不同类型的钢筋混凝土构件进行了拉拔加载试验，对三种不同类型的钢筋锚固混凝土试件在拉拔过程中的破坏过程和状态进行了观察和分析。结果表明，高强螺旋肋钢筋在拉拔载荷作用下具有良好的锚固性能。%The pull out loading test of different types of reinforced concrete members was studied in this pa-per.The failure process and state in the process of drawing are observed and analyzed through three types of reinforcement anchorage concrete test.The results showed that the high spiral ribbed steel bar has good per-formance on drawing load test.
