What is the purpose of using timber connectors in timber bridge repair?

The purpose of using timber connectors in timber bridge repair is to strengthen and reinforce timber joints, increasing their load-carrying capacity and improving the overall structural performance of the bridge. Timber connectors, such as bolts, screws, shear plates, and split rings, provide a more effective means of transferring loads between timber members compared to traditional methods like nailing alone. By distributing the load over a larger area of the wood, these connectors reduce stress concentrations and prevent premature failure of the joint. This allows for the use of smaller timber members or the repair of existing joints that have been weakened by decay or damage. Timber connectors ensure a stronger, more durable, and more reliable connection in timber bridge structures.
