7. Design an un-stiffened welded plate girder with THICK web, for a simply
supported bridge with a clear span of 24 m, subjected to a factored bending
moment 4800 kN-m and factored Shear force 1000 kN. The girder carries
two factored moving loads of 180 kN each spaced at 2 m center to centre.
The plate girder is restrained laterally and prevented from rotation.
