Designed using WoodWorks® Sizer according to the National Building Code 2015 Part 4 and the CSA O86-14 Standard - Engineering design in wood. Design must be verified by a qualified engineer.

Notes:
Snow and wind loads should not include the Importance factor (O86 5.2.3.2), which is calculated using the selected Importance Category.

For other design conditions, use WoodWorks® Sizer. These include:
  • Design of solid timber, glulam, SCL, and I-joists
  • Design of columns and walls
  • Sloped, rotated and/or notched beams
  • Partial and non-uniform loads or multiple point loads
  • Moving live, storage, controlled fluids, earthquake, dead soil and hydrostatic loads
  • Deflection limits according to your application, and cantilever deflections
  • Detailed lateral restraint conditions and lateral stability design options
  • Bearing design of supporting members
  • Fire design and floor vibration design
