![]() However it's actually using Lx = 38.0m and Ly = 6.8m. I thought the design module would use an axial force of 7.73 kN * 55.38 = 428 kN to calculate an effective length of 5.01m, for both X and Y axis buckling (since Ixx = Iyy). ![]() As a DOS program, Coldes has been used in demanding applications by reinforced concrete designers for many years. Microstran is a comprehensive software package for the analysis and design of all kinds of frame. Popularmmos curse of the pupkin prince part 3. MswinV9 User Manual - Ebook download as PDF File (. Looking at the buckling shape from the elastic critical load analysis, the buckling mode is about the Y axis (out of the truss plane) between rafters at centres that vary but a bit under 5m maximum. The elastic critical load analysis gives a buckling load factor of 55.38 for this load case. I have a 125*5 square hollow section truss chord (Ixx = Iyy = 5.44E6 mm4) that has a maximum axial compression of 7.73 kN in a particular load case. ![]() Hi, I'm hoping someone can clarify how Microstran uses the Elastic Critical Load analysis to determine compression effective length in its steel design module.
