Problem $5.$ The framing plan shown below is for a $12-$story office building with a uniform story heights of $14$ ft $.$ It must support a dead load of $60$ psf and a live load of $80$ psf $.$ The decking spans in a direction from line A toward line E$.$ Determine the required moment and shear strength for the beams and girders, and axial strength for the columns as indicated below for design by LRFD Calculate with and without live load reduction, as appropriate. Consider all beams and girders to be simply supported. i$.$ The beam between column lines $2$ and $3$ along line D$.$ ii$.$ The girder on column line $3$ between "column line E $",$ and
