  • The proposed research directed towards improving the state of knowledge, design and detailing provisions of structural steel shear tab connections. The current design procedure recommended by the Canadian Institute of Steel Construction (CISC) is limited to relatively small configurations with a single column of bolts. A lack of design guidance exists for beam-to-girder connections where either an extended shear tab or a coped beam-to-shear tab connection is used. The influence of axial load in the connection combined with shear is of particular interest. Testing of representative shear tab connections will be carried out. This will be supplemented with finite element modeling of these connections in order to evaluate a wider range of loading scenarios.
