Abstract:

Anchor bolt is an important fastening member which connects the upper structure with the concrete foundation. At present, the domestic and foreign standards have different requirements for the uplift failure mechanism, bearing capacity calculation and anchorage length of anchor bolts, causing difficulties for engineers. In this paper, the related specifications are explained, the typical calculation formulas for determining the uplift bearing capacity of anchor bolts are discussed, and the results given by these typical formulas are compared with the test results.
