Construction
Wood is relatively light in weight, because its specific weight is less than 500 kg/m³, this is an advantage, when compared against 2,000-2,500 kg/m³ for armed concrete or 7,800 kg/m³ for steel.
Wood is strong, because the efficiency of wood for structural purposes has qualities that are similar to steel.
| Material | E/f | ||
|---|---|---|---|
| Concrete | (Rck300, fck 25 M-Pascal) | 1250 | |
| Structural steel | Fe430 (ft = 430 MPa) | 480 | |
| Glued laminated timber | (BS 11 ÷ BS 18) | 470 | |
| Aluminium | (alloy 7020, ft 355 MPa) | 200 |
