"zz" corresponds to "xx" in the AISC code, i.e. The Mn values are calculated based on Chapter Whereas the LRFD code checks will display the capacities multiplied by the Phi factor: Phi*Pnc, Phi*Pnt, Phi*Mnyy, and Phi*Mnzz.Īccording to the provisions of Chapter E in the AISC 13th, 14th, or 15th Editions. Design Capacitiesįor ASD 13th, 14th, and 15th Edition code checking, Pnc/Om, Pnt/Om, Mnyy/Om and Mnzz/OmĪre the design capacities divided by the Omega safety factors. The first number is the load combination, the second is the step number: (load combination - step number). The moving load results are enveloped and the governing load combination and step location is shown for each result value under the " LC" column. See Model Display Options – Members to learn how to view the code check results graphically. The maximum code check occurs measured from the I-joint location (starting end) of the The Memberĭetail Report gives more values used to perform the code check. Provide some of the values used in the code check with the equation number If the value is greater than 9.999 it will be listed If either of them is greater than 1.0, the "z" to indicate the direction of the shear.ġ.0, the member is considered passing. The location for the shear check is followed by "y" or The Shear UC represents a similar ratio based on the The governing code equation that resulted in this value is displayed in the far right column for reference as well. This would be a factored ratio of actual to allowable stress, or demand vs capacity. The UC Max value represents the maximum Unity Check value produced by the interaction of the axial and bending stresses.
