Abstract: Gusset plates are used in steel buildings to connect bracing members to other structural members in the lateral force resisting system. Horizontal bracing is commonly used to resist lateral loads in industrial structures and in commercial buildings where floor and roof diaphragms cannot carry the loads. Wrap-around gusset plates are L-shaped plates that are used where an opening is required at the comer of the plate. This typically occurs at horizontal bracing where the gusset plate is cut out around a column. Finite element models were used to determine the behavior of wrap-around gusset plates. The plates were modeled using material and geometric nonlinearities. Five different gusset plates were modeled with geometry and material properties matching the experimental specimens of Dowswell. All of the models were loaded in tension. The loads from the finite element models were compared to the experimental loads.
