AS 5100.9:2017 PDF Download

The AS 5100.9:2017 standard provides guidelines for the design and construction of timber bridges and related structures. This standard applies to structures that utilize materials such as seasoned kiln-dried sawn timber, glued-laminated timber (glulam), and structural laminated veneer lumber (LVL). It is important to note that unseasoned timber is prohibited in this standard.

The standard covers various aspects of timber bridge design, including stress-laminated timber (SLT) decks. It outlines the requirements for the design and construction of timber bridges and structures that do not come into direct contact with the ground or water.

It's worth mentioning that if the intention is to rehabilitate or reinforce existing timber bridges using alternative materials such as round timbers or unseasoned timbers, the AS 5100.8 standard should be referenced instead.
