Question

A bridge girder AB on a simple span of
length L =14 m supports a distributed load of maximum
intensity q at mid-span and minimum intensity
q/2 at supports A and B that includes the weight of
the girder (see figure). The girder is constructed of
three plates welded to form the cross section shown.
Determine the maximum permissible load q based
upon (a) an allowable bending stress σallow =110 MPa
and (b) an allowable shear stress τallow = 50 MPa.
