Abstract:
Twenty-three 1-3/4 in. diameter and 1 in. diameter anchor bolts were tested in an investigation of the effects of clear cover, bolt diameter, embedment length, and bearing area of the anchorage device on the strength and behavior of anchor bolt installations. Failure modes are identified, and the load carrying mechanism of an anchor bolt is described. The data were combined with the results from earlier studies and analyzed using a multiple stepwise regression procedure. A simple equation for the ultimate load of a single anchor bolt loaded in tension is presented.
