Can turned timber elements be used structurally?

Yes, turned timber columns can carry significant structural loads. A 200 mm diameter solid oak column (D30 grade) can support approximately 150–200 kN in compression (depending on effective length and end conditions).

Yes, turned timber columns can carry significant structural loads. A 200 mm diameter solid oak column (D30 grade) can support approximately 150–200 kN in compression (depending on effective length and end conditions). Glulam turned columns achieve even higher capacities due to the engineered lamination removing natural defects. Structural turned columns must be designed to EN 1995-1-1 (Eurocode 5), considering: axial compression capacity, buckling (slenderness ratio), combined bending and compression, and connection design at base and capital. The turned profile does not reduce structural capacity provided the minimum diameter is maintained at critical sections.
