How far does a steel gusset plate penetrate into a wood truss?

The penetration of a steel gusset plate into a wood truss is typically about 3/8 inch. This depth is significant because it provides a secure connection between the steel plate and the wood, allowing for effective load transfer and structural integrity. The design of the gusset plate plays a critical role in maintaining the strength and stability of the truss assembly, especially under varying loads and environmental conditions. Recognizing this standard penetration depth helps in understanding how timber and steel components interact within truss systems, which is essential knowledge for fire service professionals when assessing structural safety in buildings.
