The literature search and analysis of existing headed stud and cast-in-place anchor bolt data was used to formulate an experimental program, conducted in the WJE structural laboratory. 5" from the edge. A brg is the net bearing area of the head of anchor bolt. Only a few pre-1970s steel design textbooks addressed the problem. The basic objective in structural analysis and design is to produce a structure capable of resisting all applied loads without failure during its intended life. The simplest – and strongest – form of anchor bolt is cast-in-place, with its embedded end consisting of a standard hexagonal head bolt and washer, 90-bend, or some sort of forged or welded flange (see also Stud welding).
