| |Unit Number `Pressure`

*Tree* |**Shear Y** |Shear stresses:
Sy = Fy/Ay
where Ay and Az are the shear areas calculated in accordance with selected code. Note that torsional stresses are ignored. |
| |Unit Number `Pressure`

*Tree* |**Shear Z** |Shear stresses:
Sz = Fz/Az
where Ay and Az are the shear areas calculated in accordance with selected code. Note that torsional stresses are ignored. |

*Tree* |**Bending Y +ve z** |Bending stresses:
For sections that have Iyz=0:
By = Myy/Iyy x Dz

- where Dz & Dy are the distances from the centroid to the edge of the
section in the +ve z and y directions respectively.
For sections that have non-zero Iyz: refer to the GSA manual. |
