Analytical Study by Varying the Parameters of Edge Stiffeners and Splice Plate used in Gusset Plate
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 5
Abstract
Gusset plates are used to connect diagonal members to a beam and a column, they are widely used in bridges to link the truss member at member conjunction. Gusset plates are subjected to either tensile or compressive load from diagonal members which depend upon the type of bracing system. The load from diagonal member will produce bending, shear and normal force in the gusset plate. During compressive loading , gusset plate buckling occur at the end of free edge and local buckling or crippling occur near the end of splice member. Emperical evidence from the past earthquakes and data from numerical simulations provide that secondary lateral force resisting capacity or reserve capacity plays an important role in seismic collapse behavior of low –ductility steel buildings .In 1994 Northridge earthquake, steel buildings did not collapse but there are many connections in lateral force resisting systems sustained undesirable damage because of non-ductile limits states. Hence studying of gusset plate connection plays a significant role in seismic behavior of low-ductiliy steel frame buildings. The project focus on compressive behavior and strength of gusset plate in concentric braced frames CBFs by finite element software (ANSYS 15). Also to increase the buckling strength of gusset plate connection and energy absorption behavior under cyclic loading , effect of adding edge stiffener and stiffener provided in splice plate at different thickness and width have been investigated.Also the effect of the length of splice plate is also investigated.
