What type of decks utilize glued or nailed laminated connections to transmit loads?

Timber decks are designed to utilize glued or nailed laminated connections to effectively transmit loads. This approach takes advantage of the characteristics of timber, allowing for a combination of structural stability and flexibility in design. Laminated timber connections involve layering wood veneers, which are bonded together using adhesives or fastened with nails. This not only enhances the load-bearing capacity of the deck but also minimizes the risk of failure due to individual member defects.

The unique properties of timber, such as its ability to be engineered into various forms and its strength-to-weight ratio, make it particularly suitable for laminated connections. This method is instrumental in ensuring that the load distribution and structural integrity meet safety standards in bridge designs.

In contrast, concrete decks rely primarily on reinforcement materials and concrete properties for load transmission, while steel decks utilize welded or bolted connections for strength and stability. Asphalt decks mainly serve as a surface layer for waterproofing and ride comfort rather than as primary load-bearing elements.
