Three-dimensional finite element analysis of double angle connections under tension and shear

Abstract Double angle connections welded to the beam web and bolted to the column flange are considered. They are subjected to axial tensile loads, shear loads, and a combination of these loads. The loads are increased monotonically and steel angles with three different thicknesses are analyzed. An elastic–perfectly plastic constitutive law is assumed. The connection and beam are discretized using three-dimensional finite elements in ABAQUS. Modeling of the separation of the angle from the column and modeling of the contact forces between the bolt heads and the angles are included. Load–displacement and moment–rotation curves for the three connections are generated, as well as stress distributions for the angles. In addition, an experimental test is carried out with axial loading, and two mechanical models are proposed.
