Redistribution factor for a rectangular section, km (equation (4.4c) (EC5, 6.1.6))

Combined stress condition

Equations (5.21) and (5.22) (EC5, equations (6.23) and (6.24)):

Relationships less than unity; therefore the 100 mm by 200 mm sawn section in strength class C24 will meet the ULS requirements of EC5.

Example 5.7.4 The LVL (Kerto-S) column shown in Figure E5.7.4 has a cross-section 90 mm x 200 mm, and functions under service class 2 conditions. It supports a characteristic permanent compressive action of 8 kN and a characteristic variable short-term compressive action of 19.5 kN. The loading is applied 65 mm eccentric from the y-y axis as shown in the figure and the permanent action includes an allowance to cover for the effect of the self-weight of the column. The column is 4.15 m high and at each end is effectively held in position but not in direction about the z-z axis and the y-y axis. Check that the column will meet the ULS requirements of EC5.
