摘要
通过在不同强度等级(C15~C40)的基体混凝土上植入不同深度(分别为10,13,15,20倍的钢筋直径)、不同直径(Φ12~Φ22)的钢筋,测得了大量的试验数据,并得到了植筋的几种破坏形态(钢筋拉断、钢筋拔出、混凝土锥形破坏、复合破坏),最终推导出了植筋的基本锚固长度公式。
According to the embedment of steel bars with different depths(10,13,15,20 times of diameters) and different diameters(Φ12~Φ22)into the original concrete with different strengths(C15~C40),the paper obtains a lot of data,and concludes some damage forms of embedment steel bars(tensile failure of steel bar,pullout of steel bar,destruction of vertebral bodies and comprehensive failure),and finally derives the basic anchorage length formula.
