Abstract

In order to study the anchorage performance of split double-pawl bolt, the tensile strength tests of smooth round anchor bolt and split double-pawl type anchor bolt with different anchorage lengths were carried out, and the test results were compared with the relevant literature specifications. The test shows that the strain of anchor bolt is small in the concrete, and the strain is the largest at the contact with the concrete surface. The bond failure capacity of smooth round anchor bolts increases with the increase of anchorage length, but the deeper the anchorage length, the slower the increase of the bearing capacity. The uplift bearing capacity of anchor bolts can be greatly improved by installing the pawl bolt head. The calculation method of the bonding failure bearing capacity of the smooth round anchor bolt is relatively conservative, and the experimental value of the bearing capacity is smaller than the theoretical value because the anchor head is straightened when the pawl type anchor bolt is pulled up.
