Design of Single Plate Framing Connections with A307 Bolts

The analysis and design of single plate framing connections using A325 and A490 high-strength bolts was presented in Ref. 1 and design aids for this connection with these high strength bolts was presented in Ref. 2. Recent research completed at the University of Arizona has shown that A307 bolts may also be used in single plate framing connections if slotted holes are provided either in the beam web or the framing plate. The use of these bolts may result in a more economical connection design because field inspection is not required and, additionally, significantly less connection moment is developed.
