Wood as a structural element has been used for centuries. During the first decades of the 20th century, with the appearance of concrete and steel, it became temporarily overlooked.
Nowadays, wood structures are not only competitive with common steel and concrete structures alternatives, but also better performers when it comes to fire resistance, seismic behaviour, ecological rationalism, economy in costs and aesthetic arguments.
Wood has been assuming increasingly more importance in modern architecture. Today, when architects and engineers design landmark buildings like bridges or government offices, schools, factories or warehouses, they look at timber to express a contemporary beauty which is nonetheless rooted in nature and a respect for the environment.
These structures can be built in solid wood, glued laminated timber (Glulam), LVL-Kerto (Laminated Veneer Lumber) and I-Joists.
