Moment-rotation behavior of double angle connections subjected to shear load

Double angle connections, which are welded to the beam web and bolted to the column flange, are studied to establish the effect of bolt gage distance and angle thickness. An analysis is performed to establish the moment-rotation relationship for the double angle connections and the stress distribution of each specimen is observed. They are subjected to shear loads and the elastic-perfectly plastic constitutive law is assumed. The software package ABAQUS is used to analyze the nonlinear behavior of a double angle connection. To verify the finite element model analysis, experimental tests with the same geometric and material conditions as the analysis are also conducted. (C) 2001 Elsevier Science Ltd. All rights reserved.
