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

Instructor:  Dave K. Adams, P.E., S.E., M.ASCE

Course Length: 1.5 Hours

Purpose and Background

Steel ordinary moment frames are often selected to create an economical structural system for both building and non-building structures, but their use is limited in higher seismic design category regions. Additionally, the design process for frames constructed of unconventional shapes is not very clear in AISC 360-10 or AISC 341-10. Frames that are built of anything other than wide-flange members may fall into the category of "alternative designs" and an engineer needs to understand how to produce a reliable, defensible design that complies with the intent of ASCE 7-10. This webinar discusses what constitutes an alternative design. It presents procedures for different seismic design category regions.

Primary Discussion Topics

• What is an "alternative design"?
• Procedures for different seismic design category regions
• Example: Moment frame using HSS members
• Example: Moment frame using truss members
• Example: Knee-braced moment frame

Learning Outcomes

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

• Comprehend the scope of restrictions and design requirements from ASCE 7-10
• Determine appropriate sections for design from AISC 360-10 and AISC 341-10
• Know how to calculate three different types of alternative moment frames

Webinar Benefits

• Understand the provisions of ASCE 7-10, AISC 360-10 and AISC 341-10 relative to steel ordinary moment frames
• Learn how to calculate the nominal strength and deflection of three alternative frame systems
• Discover economical applications for building and non-building structures
• Determine how the codes distinguish between "building" and "non-building" structures
• Defend alternative designs with confidence
• Expand knowledge on how different codes are related to one another
• Examine the differences between ordinary, intermediate, and special moment frames

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).

How to Earn your CEUs/PDHs and Receive Your Certificate of Completion

To receive your certificate of completion, you will need to complete a short on-line post-test and receive a passing score of 70% or higher within 1 year of purchasing the course.

How do I convert CEUs to PDHs?

1.0 CEU = 10 PDHs [Example: 0.1 CEU = 1 PDH]
