Question
1. The truck loading shown below represents the design load for an 80-foot, simple span bridge
girder. Note the loads represent wheel loads and not axle loads. Determine:
a) The absolute maximum value of shear for the girder.
b) The absolute maximum value of moment for the girder.
c) The maximum value of moment when the 24 kip load is positioned at the midspan of the
girder.
d) The value of moment at the 24 kip load for the load placement that does not govern when
determining the absolute maximum value of moment for the girder (item b).
