When evaluating the web crippling capacity of a flat pan standing seam roof panel, should the multi-web deck coefficients be used?
Answer No. 7 Because multi-web deck coefficients are based on tests of trapezoidal profiles that are a continuum at the corrugation and the flat pan panel is not, the multi-web deck coefficients may not be applicable. I suggest using the Z-section coefficients to evaluate the web crippling of each web and then adding the web crippling capacities to determine the support reaction. Back to top Wall Studs Question No. 8 The AISI Wall Stud Standard indicates that the stud should be installed in accordance with the General Provisions Standard. In the General Provisions Section C3.4.1 it is stated that the stud is to be installed plumb. What is “plumb”? Answer No. 8 Plumbness is not defined in the AISI specification or standards or the building codes. However, the AIA MasterSpec Section 05400 on Cold-Formed Steel Framing states in Section 3.3 on Installation, General subsection J on Erection Tolerances to “install cold-formed metal framing level, plumb, and true to line to a maximum allowabl
