The teleconference method allows the audience to see this webinar straight from my office, without having to travel. I have attended many ASCE webinars and find that ASCE knows how to put together an effective webinar. - Anonymous Attendee

Purpose and Background

The 2016 edition of ASCE 7 contains a number of important changes that affect the seismic design of nonbuilding structures. This webinar discusses these important changes and how these changes impact the design and construction of nonbuilding structures. In addition, changes made to the provisions to help clarify the application of the provisions of Chapter 15 of ASCE 7-16 are identified and discussed.

Many of the changes to be discussed in this webinar are driven by poor performance of some nonbuilding structures in past seismic events, the need to conform some existing industry standards to the basic requirements found in ASCE 7, or confusing language found in previous editions of ASCE 7.

Learning Outcomes

The following learning outcomes have been established for webinar participants:

• At the conclusion of this webinar, participants will be able to apply the new vertical seismic ground motions to nonbuilding structures
• Upon completion of this webinar, learners will be able to identify when the accidental torsion requirements of ASCE 7-16 do not apply to nonbuilding structures
• At the conclusion of this webinar, participants will be able to correctly determine the seismic forces on free standing cantilever walls and fences
• Upon completion of this webinar, learners will be able to correctly specify ASTM F1554 anchors

Webinar Benefits

• Understand the new vertical seismic ground motion requirements for nonbuilding structures
• Learn how to properly apply the requirements of ASCE 7-10 Chapter 15 for accidental torsion to nonbuilding structuresUnderstand the requirements for using shallow foundations to support nonbuilding structures on liquefiable soils
• Find out the new seismic requirements for freestanding cantilever walls and fences
• Find out the latest seismic requirements for steel cantilever storage racks
• Learn how to properly specify ASTM F1554 anchors for use  with nonbuilding structures
• Avoid costly errors by learning clarifications of some existing Chapter 15 provisions

Intended Audience

Structural engineers who design nonbuilding structures will benefit from this webinar.
