    - The welded structures are subjected to eccentric loads, torsional or bending moments.

    - Welds should always be designed in such a way that the line force passes through the centroid of welded group.

    - The eccentric load can be replaced by both parallel or twisting moment.

    - Parallel force: Parallel force which is passed through centre of gravity of welded group results in direct shear stress or primary shear stress.

    - Twisting moment: Twisting moment through C.G. results in secondary or torsional shear stress.
