Formula of mu in steel design
WebWhere Mu = Mn/Omega = FyZx, thus Zx = Mu/Fy. 3. Enter the "W-section Beam Selection by Zx" chart and find the beam with the same or larger Zx. Check the flexural strength either phiMn for LRFD or Mn/Omega to insure it is equal to or greater than Mu. 4. Check the unbraced length factors, Lp and Lr. http://www.cecalc.com/SteelBeamsDesign.aspx

WebThe LRFD manual also provides extensive information and design tables for the design of beams and other flexural members. 3. Stability of Beam Sections As long as a beam remain stable up to the fully plastic condition as depicted on Figure 2, the nominal moment strength can be taken as the plastic moment capacity as given in Equations 4 and 5.
