Design Assumptions:
1.
Roof Load = 0.62 kPa (Asphalt shingle roof)
2.
Design Standards: CSA 086-01, “Engineering Design in Wood”
3.
Design Assumptions:
- The studs are braced from buckling about their weak axis by the attachment of the wall sheathing.
- The post is designed for axial loading applied at the centre of the stud cross-section (concentric loading).
- Stud grade material has been assumed.
- The stud resistance is based on the compressive resistance parallel to grain (Pr) and the bearing resistance of the wall plate (Qr).
- In the calculation of Pr, a system factor (KH) of 1.0 was used.
- In the calculation of Qr, a size factor (Kzcp) of 1.15 was used since the wall plate width is greater than two times the thickness. A length of bearing factor (KB) of 1.0 was used since the stud post can occur at a splice in the wall plate.
- The post size has been limited to 5 plies.
- The post size is maintained through all storeys directly below the girder truss or beam until the load is transferred to the foundation wall.
