What will be an ideal response?
(a) Draw the influence lines for the reactions at B and E, the shear between CD, the moment at B and D for the girder HG in Figure P12.18. (b) If the dead load of the floor system (stringers and slab) is approximated by a uniformly distributed load of 3 kips/ft, the reaction of the floor beam’s dead load to each panel point equals 1.5 kips, and the deadweight of the girder is 2.4 kips/ft, determine the moment in the girder at D and the shear just to the right of C.
