2 Two identical low carbon steel plates with same thickness are to be joined by welding
process. A butt joint and lap joint are proposed, as shown in Figure P5.4. The welded
joint is supposed to carry a static tension load of F. The allowable tensile stress of the
weld is [ ] = 200 MPa and the allowable shear stress is [ ] = 150 MPa. Which design
is better?
Structure Design Problems
1 Compare the two designs in Figure P5.6. Assume the dimensions of plates and rivets,
the number of rivets and the materials of plates and rivets are exactly the same in
the two layouts.
