SNOW LOADS ON SLOPED ROOFS.

The author proposes design recommendations using the results from a field investigation, wherein the effects of slope and thermal environment are measured independently of other snow accumulation factors. Data from instrumented sloped roofs are combined with observations from a group of similar structures. A flat-roof building with four different thermal conditions is monitored as a control for the sloped roofs. Results are widely applicable since the field site has significant snow accumulation during the years of study. Regression analysis is used to formulate new sloped roof coefficient; the coefficient errors are normally distributed.
