D11.A.4.3Shear
Section web shear capacity, φVv
, is
calculated per Cl.5.11, including both shear yield and shear buckling
capacities. Once the capacity is obtained, the ratio of the shear force acting
on the cross section to the shear capacity of the section is calculated. If any
of the ratios (for both local Y & Z-axes) exceed 1.0 or the allowable value
provided using the
RATIO parameter, the section is considered to have failed
under shear.
The following table highlights which shear capacities are calculated for different profile types.
| General Profile Type | Shear Checks |
|---|---|
| I-Section (i.e., parallel to minor principal axis) | Calculated for web only |
| T-Section | |
| Channel | |
| Angle | |
| Tube | Calculated parallel to both z & y principal axes |
| Pipe | Per NZS3404 5.11.4 |
Only unstiffened web capacities are calculated. Stiffened webs are not considered. Bearing capacities are not considered.
The
TSP design parameter is used in shear capacity
calculations.
