A beam AB to be secured to the wall panel needs to be sized by the application of permanent joint design (treated as fillet welded lines in torsion) as illustrated in Figure 1. The beam is expected to carry a vertical downward static load with the magnitude of F= 81,000 N. The welded joint will use an electrode having strength, Sweld = 126 MPa. Distance Lo=360 mm represents a moment arm between the force at B and centroid of the weld group. Devise; a) b) schematic sketches representing the geometry of fillet welds treated as lines and the corresponding maximum shear stress diagram of the joint, and design the minimum weld size t matching the strength of the given welding electrode, assuming that t remains consistent throughout the welding path.
