- In Tables 2–9:
- Item 1): calculations of columns, based on the formulae applied as per EN-1995 Eurocode 5 [6]
- Items 2)–5): calculations with the formulae based on the theory presented in Timoshenko and Gere [5], where:
- 2) Calculations for columns with truss made of wood
- 3) Calculations for columns with truss made of plywood
- 4) Calculations for columns with truss made of fibreboard
- 5) Calculations for columns with truss made of particleboard
- λef as per formulae (1), (23) and (24), kc instability factor, n load-bearing capacity of a column, g = 20 mm and g = 24 mm of truss elements thickness
