Design of structural timber connections
Connections are an essential part of any structure, and in timber structures they are often the most critical part of a design. The timber section size is often determined by the strength of the section remaining after drilling holes for bolts or dowels, or by the spacing requirements for the fasteners, rather than the load-carrying capacity of the timber. Therefore the design of connections is an important section of any timber design standard.
When selecting and detailing connections for a particular application, designers must consider four criteria:
- Load transfer
- Fire resistance
This Wood Information Sheet (WIS) focuses on the load transfer aspect and is intended mainly for engineers and architects. This WIS is an overview of the subject with signposts to more detailed sources that are listed at the end.
- Connection types
- Fastening methods
- Design of laterally loaded connections
- Design of axially loaded connections
- Spacing of fasteners
This Wood Information Sheet was reviewed in February 2017 and minor corrections were made to the references section.

In many situations, timber and wood-based materials may be used in their natural, untreated state. However, flame-retardant (FR) treatments extend their use to situations that demand enhanced 'reaction to fire' properties.
This Wood Information Sheet (WIS) covers treatments that may be applied to wood and wood-based products both...
Fire-resisting doorsets are required to be able to contain a fully
developed fire, to facilitate escape of a building’s occupants and allow
fire-fighting, and to protect the structure from the effects of fire. The
doorset therefore must have resistance to fire, expressed in terms of
