Resistance of Eccentrically Connected Gusset Plates in Compression

Popis výsledku v původním jazyce

An experimental study with six bolted single-brace eccentric gusset plate connection specimens is presented in this paper. Using Abaqus FEA, numerical models are created and are validated on the tested specimens. Then, a numerical 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 which assumes the formation of two plastic hinges, a second-order effect and reduction of the plate bending resistance due to the present axial force.
