Hello, Dr. Swanson. I have another question. I saw how that method used to determine the K factor for the stepped crane column with lower shaft and upper shaft. But I have doubts that are correct. Can you tell, please - can an engineer use that method for the stepped column? P.S. sorry for my English, I hope you can understand what I try to ask😊
I originally learned of simplified equations for the effective length factors in my undergraduate steel design class taught by Reidar Bjorhovde at the University of Pittsburgh. They are described in his textbook, Load and Resistance Factor Design of Steel Structures by Louis F. Geschwindner, Robert O. Disque, and Reidar Bjorhovde, published in 1994 that is now quite outdated. Geschwindner’s current textbook, Unified Design of Steel Structures by Louis F. Geschwindner, Judy Liu, and Charles J. Carter, also includes the equations. Both texts include a reference to a 1966 AISC Engineering Journal paper by Pierre Dumonteil, “Simple Equations for Effective Length Factors,” as the source of the equations. doi.org/10.62913/engj.v29i3.592

Great video. Thanks for that. Can you tell from which document you took the formula for determining K, which can be used instead alignment chart?
