Placed your final answer on a box or use highlighter.1. From the figure shows a four-span beam having span lengths AB = 8 m, BC = 9 m, CD = 8 m, and DE = 7 m. The total factoreddead load is 7 kN/m and the factored live load is 8 kN/m. The beam is built into a girder at the masonry wall at A which does notoffer restraint to beam AB.
