INSTRUCTOR: 
Robert Pekelnicky, P.E., S.E., F.SEI

Purpose and Background

This course will present an overview of the updates to ASCE 41 found in the 2023 edition of the standard. The course will also focus on changes to the seismic hazard parameters, majors revisions to the material testing provisions, and updates to the linear and nonlinear analysis procedures.

Benefits and Learning Outcomes

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

• Explain the changes to the seismic hazard parameters and be able to determine a multi-period response spectra for your building site.
• Identify how to proceed with a seismic evaluation without material testing.
• Implement new calculations for forces on force-controlled elements using linear procedures.
• Explain the procedures for including or excluding secondary components from a linear or nonlinear analysis.
• Describe the changes to what constitutes an unacceptable response in a nonlinear analysis.

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

This course is worth 0.2 CEUs/2 PDHs. To receive your certificate of completion, you will need to attend the live session and/or watch the recording(s) and complete the post-session survey. If the course is taken On-Demand, there will also be a 10 multiple choice question post-test. You must pass with 70% or higher within 365 days of the purchase.

How do I convert CEUs to PDHs?

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