Course Length:  1 hour

Sponsored by ASCE's Structural Engineering Institute and ASCE Continuing Education.

I liked hearing about the background behind some of the ASCE 7 snow load provisions.

Purpose and Background

This webinar will provide practicing structural engineers with an understanding of the new, updated and changed snow and rain load provisions of ASCE 7-16. Attendees will learn the basis for the changes to snow and rain provisions including the "what" (specific details of the new provisions), and the "why" (reasons for the changes).

The webinar will cover all significant changes  to ASCE 7-16. For each changethere will be a brief review of the 2010 provisions and then a more detailed discussion of the what and why of the new provisions. Specifically, the webinar will cover the following new snow loading provisions of ASCE 7-16:new state ground snow load tables, drifts at RTUs, canopy drifts, drifts at roof step in series, drifts at re-enterant corners, importance factor for drifts, Open Frame and Air Supported structures. The webinar will also cover the following new rain load provisions; hazard definition, revised  head-flow relations and ponding susceptibility.. The webinar will conclude with a question and answer session.

Primary Discussion Topics

• New Pg tables
• Revised drift load provisions
• New snow provisions for Open Frame  and Air Supported structures
• Rain hazard definition
• Ponding susceptibility

Learning Outcomes

Upon completion of this course, you will be able to:

• Examine drift loads for canopies and re-enterant corners
• Explore snow loading for Open Frame structuresSnow loading for Air Supported structures
• Recognize determination of ponding susceptible roofs

Benefits for Participants

• Understand the snow load hazard
• Understand the rain load hazard
• Learn appropriate snow and rain loading considerations
• Avoid collapse from inadequate design loading

Assessment of Learning Outcomes

Students' achievement of the learning outcomes will be assessed via a short post-assessment (true-false, multiple choice and fill in the blank questions).

Intended Audience

This webinar is intended for both private and public sector structural engineers involved in the design, analysis and/or review of building structures. Although not absolutely necessary, it is expected that attendees have a working knowledge of the ASCE 7-10 snow and rain load provisions. The webinar will focus on what is NEW in the 7-16  provisions, as opposed to a general review of snow and rain loading provisions.

Webinar Outline

• New and revised Snow Load provisions
• New and revised Rain Load provisions
