Section 8.2.2

Determining Applicable Flexural Limit States

Last Revised: 07/30/2011

The selection of the appropriate limit states, in the appropriate form, can be a bit confusing since the 13^th edition of the SCM.  To help the process, Table User Note F1.1 has been provided (see SCM page 16.1-45).  This table, however, does not preclude reading of the criteria statements at the beginning of each section of chapter F.  It has been found that beginning students are often times confused when selecting the appropriate SCM criteria. To aid the beginning student, additional tables are provided here as another view of the selection for I shaped members.

The choice of Chapter F section depends on the shape of the section and the slenderness of the cross sectional plate elements.  While the sections address many of the same limit states, they do so slightly different in each case.  The following tables may help to select the correct limit states in the correct sections.
