There was a time long ago, in a galaxy not far away, that columns were designed for a length, L, without K. Then, in the early 1960s, the now-familiar K-factor was codified. Over the many decades since, it came to seem as if the K-factor had always existed. Now, we have methods of design by which columns can be designed that take into account stability using KL = L again. This webinar explores the origins and development of K, the effective length factor, and why it often can now be taken equal to 1.
This course is based on a past AISC Live Webinar.
