Seismic Gusset Rotation Capacity/Clearance-Per the User Note in AISC 341-10 section F2.6c(3)(b),accommodation of inelastic rotation is typically accomplished by terminating the brace before the line of restraint.The commentary on this section suggests a 2t linear offset.This check includes verification of this suggested geometry.STUDY OF FLEXURAL BEHAVIOUR OF STEEL BEAMbeam-column joints are possible to increase.To know the increasing capacity of beam-column connection with gusset plate are determined by conducting the experimental and analytical program.An experimental research demonstrates the actual behaviour of steel beam-column connection with gusset plate.There are four number of specimens are testedSTRUCTURE magazine Braced Frames The Quest for DuctilitySuch large gussets may result in weld failure and gusset plate separation from the beam-column joint.New design requirements mandate this to be remedied by requiring consideration of the design of such connections for flexural forces and rotation capacity.
