Abstract: An improved building structure and method for making steel frame buildings includes a beam-to-column or beams-to-column joint or connection which is most preferably shop fabricated (as opposed to on-site fabrication) and which offers a considerable savings in both steel requirements (i.e., material savings) and labor to make the joint connection. Also, because material utilization is improved in the connection, the new structure is more resistant to damage by seismic events (i.e., earthquake), by severe weather, and to damage from blast effects (i.e., terrorist attack or accident), than was the prior technology. The improved building structure also mitigates against progressive collapse of the building.
