Consider pattern loading (skip loading) for live load (shown black on the sketch) for the simply supported beam with overhang. DL Vmax D. 20' 8' M+ max WD = 1.2 x 2 = 2.4 k/ ft DI. WL = 1.6 x 3 = 4.8 k/ ft M- max a. Draw bending moment diagrams for three loading conditions. i) Live Load + Dead Load over entire span ii) Live Load over the simply supported beam + Dead Load over entire span iii) Live load on the overhang + Dead Load over entire span b. Using the bending moment diagrams for three skip loading you have calculated, show maximum positive moment and negative moment with corresponding location.
