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 |

Famous quotes containing the word construction:
“The construction of life is at present in the power of facts far more than convictions.”
—Walter Benjamin (1892–1940)
“No real “vital” character in fiction is altogether a conscious construction of the author. On the contrary, it may be a sort of parasitic growth upon the author’s personality, developing by internal necessity as much as by external addition.”
—T.S. (Thomas Stearns)
“There is, I think, no point in the philosophy of progressive education which is sounder than its emphasis upon the importance of the participation of the learner in the formation of the purposes which direct his activities in the learning process, just as there is no defect in traditional education greater than its failure to secure the active cooperation of the pupil in construction of the purposes involved in his studying.”
—John Dewey (1859–1952)
