However, the tables below cover most of the common cases. 3. Our task is to determine the mid-span deflection and the maximum deflection. (a). at midspan. 1. Calculate the factored design loads (without self-weight). Slope at both end will not be 0. Example 2.2 Design a simply supported beam subjected to uniformly distributed dead load of 450 lbs/ft. and B.M. The bending moment curve is a piecewise curve of slope V (x), a function of x of degree 2 on the beam, with a jump at position C. Unlike the uniformly distributed load, the slope of the bending moment curve due to the variable distributed load is a function of x of degree 2, therefore the bending moment curve is a cubic curve of third degree .
