Course Length: 1 Hour

This webinar was co-sponsored by ASCE's Structural Engineering Institute and ASCE Continuing Education. 

Purpose and Background

The 2010 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 7-10 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

You will become familiar with changes to the nonbuilding structures requirements and applications of these provisions made to Chapter 15 of ASCE 7-10.

Webinar Benefits

• Avoid costly errors in the design of large breach openings in reinforced concrete stacks
• Learn how to properly apply the requirements of ASCE 7-10 Chapter 15 to reinforced concrete tanks
• Find out the latest methods to determine the seismic free board in ground supported tanks
• Understand the anchorage requirements for nonbuilding structures
• Find out the latest seismic requirements for steel storage racks
• Learn the correct interpretation of the Chapter 15 requirements for piers and wharves
• 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.
