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

Instructor:  Nicholas Lutzweiler, P.E., S.E., M.ASCE

Course Length: 1.5 Hours

Purpose and Background

Graphic statics was at one time a significant structural analysis tool. The intuition that comes from it can still resonate today. While it likely would not be efficient to design this way in today's busy consulting world, there is still value in understanding the past. In addition, graphic statics is just plain interesting, and frankly an art. Certain intuition can be learned from solving graphic statics problems that is not as easily seen when using computer-based analysis software. A gut feeling can be developed for all trusses after solving some examples. This webinar helps engineers value the past and see how it can still be applied in the now. It helps engineers understand the history of graphic statics and its significance today. It introduces them to the subject and allow them to have confidence learning more about the applications for graphic statics.

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]
