Abstract:

The building roof snowmelt model, which was based on the previous mass and energy balance models, was adopted to compute the sliding snow loads on roofs in several typical countries. A simplified calculation formula that could compute the coefficient of sliding snow load was given. And a comparative study was made between the results from the simplified calculation formula and those from the load codes of some countries.
