This thesis presents a study of all-bolted extended double angles in a beam-to-girder connection in order to investigate the strength of the web of the girder that is supporting the beam. Extended connections have multiple advantages over the standard connections: Since coping is avoided, it reduces skilled labor and time resulting in reduced construction costs. Due to coping, reduced beam sections are exposed to possible failure due to lateral torsional buckling and local web buckling of the coped section. A set of double angle extended beam-to-girder connections were designed for a range of angle thicknesses, girder web thicknesses, girder depths, beam depths, and bolt diameters using current AISC specifications. Only one sided beam-to-girder connections were considered in this study. Three dimensional non-linear finite element models of these connections were developed and studied. All of the connection components such as beam, girder, double angles and bolts were modelled using solid elements. A monotonically increasing load was applied on supported beam until failure. The results of this numerical modelling were compared with AISC expected ultimate shear strengths of the connections. Investigation of girder web strength was also carried out. Plastic mechanism at the girder web was not seen in any of the connection. Girder web showed enough strength for the effects due to eccentricity. AISC design equations were found to be conservative in predicting the ultimate strength of the connection. Design suggestions were made based on the behavior of component parts in the connection.
