The actual stress is computed at the top and bottom of each Tee section. The overall moment (Mz) at the span point corresponding to the middle of the hole is converted to an axial force and a moment on the Tee. ![]() The effective cross section at these locations is a Tee. This is checked at the middle of the hole locations. The ratio is computed by dividing the actual stress by the allowable stress. Following this, the allowable bending stress is computed per chapter F of the same. The rules applicable to I-shaped sections are used for this. ![]() The actual bending stress is computed at the middle of the web post location and is obtained by dividing the moment by the section modulus of the full section.įor computing the allowable bending stress, the compactness of the section is first determined in accordance with Table B5.1 in the Chapter B of the AISC 9 th edition specifications. This is the region of the member where the full cross section is active, without interference of the holes. Global bending check is done at the web post section. Cross section considered for limit states Design For
