Abstract
Diagonal bracing systems are frequently employed in steel framed structures to provide stability and to resist both wind and seismic loads. It is common in such bracing systems to use gusset plates to attach the diagonal braces to the main framing members. Analytical studies have shown that the force distribution in a gusseted connection depends upon all of the structural components constituting the connection including the gusset plate, diagonal brace or braces, column, beam, and fasteners (bolts or welds). Research is currently in progress at the National Bureau of Standards (NBS) to determine experimentally the behavior of gusseted, connections. Three 3/4-scale braced frame subassemblages, each with a different connection detail will be tested. The objectives of the NBS experimental program on braced frame connections are presented. The selection of the subassemblage to be tested, based on prototype behavior, is described. And the details of the proposed test specimens and loading are given.
