Cross-laminated timber: structural principles
This revision includes an additional detail for floor supported on glulam beam, as well as various minor amendments.
Cross-laminated timber (CLT) offers opportunities to use timber in taller structures with wider spans where designers would traditionally have used materials such as steel, concrete and masonry by default. As with any new structural material, it is essential that designers understand how to achieve CLTâ€™s potential while respecting its limitations.
This Wood Information Sheet (WIS) is an overview of the subject with signposts to more detailed sources that are listed at the end.

Wood products have traditionally been used as lining materials for formwork to concrete. Although timber planks were originally used as formwork linings, wood-based panel products are now more common in modern concrete construction.

With engineered timber becoming an increasingly prevalent component in construction, it is important for members of the construction industry to understand not only the benefits and properties of Engineered wood products, but also the different types.
With modified wood products being improved upon on a seemingly daily basis, this...
Wood-based panel products are sheet materials that contain a significant amount of wood in the form of strips, veneers, chips, strands or fibres. The categories described in this Wood Information Sheet (WIS) are:
- Oriented strand board (OSB)
- Fibre building boards
Within each of the above...
