Abstract
Structural analysis of the loaded welded connection of plates requires the determination of the design strength of the plate specially in bridge Structures. Simple welded shear tab connections are used regularly in structural engineering practice. Many engineers who still use Allowable Stress Design use the elastic method in designing these connections. To determine the stresses in a plate at the welded joint of a simple shear tab connection using finite element analysis, and to compare those results to the simplified elastic analyses used in structural engineering practice. In particular we will look at the tension and compression stresses at the extreme fibers of the weld connection along with the shear stress at the middle of the weld. ANSYS will be used for the finite element analysis. In conclusion, both the finite element analysis approach and the allowable stress design approach result in almost identical maximum shear stresses in the plate at the welded joint. The two approaches do not provide similar results for the maximum tension and compression stresses at the ends of the joint.
