Single-angle welded–bolted beam connections

This paper reports the results of the last phase of an experimental investigation of load tests on full-size single-angle connections in which one leg of the angle is connected to a beam with ASTM A 325 high-strength bolts and the other leg is welded to the supporting member. In the present study, one series of tests has shown that connections with "short slotted" holes are as reliable as similar connections with round holes but provide a greater measure of flexibility. Two other series of connections with round holes, but with different weld patterns, proved to be flexible but could not carry the desired shears.
