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.   0:00 – Introduction 0:37 – Resources 2:17 – Overview of the Process 3:42 – Factors Affecting Snow Loads 5:30 – Flat Roof Snow Loads 6:26 – Ground Snow Loads 10:24 – Case Study Regions 13:25 – Roof Exposure 15:17 – Surface Roughness Categories 19:11 – Roof Thermal Conditions 21:35 – Snow Importance Factor 22:30 – Minimum Snow Loads 23:54 – Sloped Roof Snow Loads 26:03 – Slippery vs Nonslippery Roofs 28:41 – Review and Summary Keywords: ASCE 7-16: 2016 American Society of Civil Engineers Minimum Design Loads and Associated Criteria for Buildings and Other Structures IBC 2018: International Building Code Snow Loads, Structural Engineering, Load Determination
