This is the first of two lectures addressing snow loads. This presentation covers what I call “Basic Snow Loads,” and addressed ground snow loads, determination of structure coefficients that are needed to calculate flat roof snow loads, and finally sloped-roof snow loads. Advanced topics are covered in a second separate presentation, which includes snow drifts, sliding snow, rain-on-snow surcharges, etc.
