  1. In Tables 2, 3 and 4:
  2. –  Item 1: calculations of columns, based on the formulae applied as per EN-1995 Eurocode 5 [4]
  3. –  Items 2, 3, 4, 5: calculations with the formulae based on the theory presented in Timoshenko and Gere [3], where:
  4.     2: Calculations of columns with timber gussets
  5.     3: Calculations of columns with plywood gussets
  6.     4: Calculations of columns with chipboard gussets
  7.     5: Calculations of columns with fibreboard gussets
  8.        λ ef – as per formulae (1) and (21)
  9.        k c – instability factor
  10.        n – load-bearing capacity of a column
