This structural loading diagram outlines the design loads for Joist Type 3 (J3) with a superimposed dead load of 0.330 kips per foot, a roof live load of 0.12 kips per foot, positive wind load of 0.096 kips per foot, and snow load of 0.144 kips per foot across the span. Negative wind load is indicated at -0.165 kips per foot uniformly and -0.202 kips per foot across a 20-foot segment. Snow load increases to a peak of 0.468 kips per foot over a 13-foot span portion.
