Compressive Resistance of Eccentrically Connected Gusset Plates
Original language description
A new experimental study with six bolted single-brace eccentric gusset plate connection specimens is presented in this paper. The observed collapse mechanism with two plastic hinges is consistent with previous findings presented by other researchers. Using Abaqus finite-element analysis (FEA), numerical models are created and are validated on the tested specimens. Then, an extensive parametric study follows, showing the influence of eight geometrical and material parameters on the ultimate and critical load of the connection. Finally, the results are compared with the predictions of existing analytical models. It is shown that both the placement and the number of bolts in the connection have almost no effect on the compressive resistance. Furthermore, it is proven that parts of the gusset plate outside the so-called Whitmore section actually contribute to the compressive resistance of the connection, although they may not develop a full plastic hinge. For the tested connection geometry, the best and safe analytical prediction is given by a model that assumes the formation of two plastic hinges, a critical buckling load and reduction of the plate bending resistance due to the present axial force.
