Model the two spans for the concrete girder option of the Project Bridge

and determine shears and moments due to DC$1($dead load of components,

non$-$composite$),$ DC$2($dead load of components, composite$)$ and DW $($dead

load of utilities and overlay$)$ effects on an interior girder. Plot the shear and

moment diagrams. Assume each BT$-54$ girder supports a tributary width of

deck for DC$1$ calculations. Assume parapet $(0\mathrm{.}400$ klf per parapet$)$ loading

and wearing surface $(35psf)$ loading are distributed equally to all four gird$-$

ers. Take the girder spacing, $\text{'}S\text{'}$ equal to $9ft3$ inches.
