Glulam Connection Details

Proper connection details are critical to the structural performance and serviceability of any timber-framed structure. The larger sizes and longer spans of glued laminated (glulam) timbers make the proper detailing of connections even more important.

This publication outlines the importance of proper glulam connections and highlights key areas to consider, including careful consideration of moisture-related expansion and contraction, transfer of design loads without causing localized stress concentrations, which can lead to tension perpendicular-to-grain failures and eccentricity in the connection as finally avoiding moisture exposure of end grain.

This publication is designed for: engineers, builders, architects, building officials

Key sections include:

• Seven principles to follow for efficient, durable and structurally sound connections

• Diagrams of 19 glulam connections

  • Connections include beam-to-bearing, beam-to-beam, heavy concentrated load suspended from beam, cantilever beam connection, beam-to-column, truss connectors and more
