Torsional Stability and Lap Eccentricity in Extended Shear Tabs [N27A]

Based on an AISC Engineering Journal paper from the Second Quarter of 2011, the design procedure for extended single-plate connections will be presented which will include a check of lateral-torsional stability of the extended single plate, which resembles a double-coped beam. Research has shown that coping of beams can reduce the lateral-torsional buckling strength of beams. This paper presents a proposal to use the double-coped-beam concept to ensure the lateral-torsional stability of the extended plate. The question of stiffeners and the effect of the small eccentricity due to the lapping of the plate with the beam web will also be addressed.
