Ultrasonic stress measurement for evaluating the adequacy of gusset plates
… challenge in determining the safety margin for gusset plates is determining the level of stresses carried in the plate. Present technologies are unable to evaluate the dead, live and residual stresses maintained in gusset plates. The goal of the research presented in this thesis is to improve …

Beam-column connection flexural behavior and seismic collapse performance of concentrically braced frames
… behavior of beam-column connections with gusset plates and their ability to improve the seismic collapse performance of concentrically braced frames. Previous experimental and field observations demonstrated that reserve lateral force-resisting capacity due to the flexural strength of …

Experimental analysis of king-post truss with semi-rigid joints
Joining wooden rafters with plywood gusset plates using helically threaded nails to form roof trusses has been widely developed in recent years. Actually, the nailed member has proven to be extremely strong and stiff, but it is not perfectly rigid. The effect of non-rigidity of joints in resisting …

Study of the I-35W Highway Bridge Collapse Mechanism
… inadequate load carrying capacity of the steel gusset plates connecting the main truss members at four specific nodes. Permanent deformations of the members in proximity to these nodes were documented and a surveillance video camera recorded the collapse event in a major section of the …

Seismic Rehabilitation of Steel Concentrically Braced Frames Vulnerable to Soft-Story Failure Through Implementation of Rocking Cores
… results and explicitly take into account gusset plates, member yielding, brace buckling, brace rupture, and P-Delta effect. Eigenvalue analyses are first conducted to investigate the effect of RC on system modal properties. It is found that the added RC generally does not significantly …

Buckling-Restrained Braced Frame Connection Design and Testing
… a gap in the beam beyond the edge of the beam-gusset weld that acts as a hinge and reduces moment forces transferred to the connection; it is bridged by splice plates that are bolted to the beam top flanges. The splice plates and buckling-restrained braces are the only frame components that are …
