Structural design and engineering in timber construction

Timber and timber frame construction is particularly ecological. This is because it uses renewable raw materials and employs them according to their properties. For instance, softwood has a comparable compressive strength to concrete when aligned with the grain. Load-bearing and bracing facings made from board materials are used for wind bracing. Last but not least, timber-framed buildings can withstand earthquakes with little to no damage.

Bracing of cladding in accordance with Eurocode 5

The structural safety proof for a timber board wall with a bracing facing made of Rigips boards can be carried out in accordance with Eurocode 5 (DIN EN 1995-1-1). Both the Rigidur H gypsum fiberboard according to ETA-08/0147 and the glass fleece reinforced gypsum board Glasroc X according to ETA-21/0179 are approved for use as load-bearing and bracing facing in timber construction. These documents contain the board properties required for design.
In addition, the strength properties of Rigips construction and fire protection boards are regulated by standards and can be found in the national application document for Eurocode 5, DIN EN 1995-1-1/NA.

Earthquake-resistant construction with Rigips

Thanks to its construction method, timber construction is particularly well-suited to earthquake-resistant buildings. Buildings intended to protect the population, such as hospitals and fire stations, are naturally held to higher standards than residential buildings. There are good reasons why other public buildings, such as schools and kindergartens, are also built using timber construction: They are robust enough to withstand earthquakes. In the event of an earthquake, the seismic forces are absorbed by the building components through deformation, preventing collapse. This behaviour is commonly referred to as energy dissipation.
The applicability of Rigips boards for transferring earthquake loads, even in the highest earthquake zone 3, is governed by general construction type approvals.
