$(24)6.$ Using the slope$-$defection method or the moment$-$distribution method, analyze the twospan beam shown. In addition to the effects of the loading shown, stresses and strains are caused because the central support is $64mm$ below the elevation of the two end supports. Draw shear force and bending moment diagrams. For each diagram and both beams, calculate and indicate the magnitudes of the maximum and minimum ordinates $($Minimum ordinates are frequently negative values$).$ The continuous beam is straight and inextensible; it has $EI=2\mathrm{.}0{10}^{4}kN*m^2.$
