STR04 L05a - Basic Snow Loads

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.

Thank you so much! I'm a young engineering student trying to learn all of the design loads and these videos are incredibly helpful!

Simply excellent

Great video! Thank you so much!

Thank you for posting this excellent resource! I am trying to study for the SE vertical breadth section, and this serves as a great introductory to ASCE 7 snow loads, since I never deal with this at all.
