Plywood Design Specification, Supplement 4-23: Design and Fabrication of Sandwich Panels

Plywood sandwich panels combine thin, strong plywood facings with lightweight core materials to create efficient structural assemblies. This publication provides comprehensive engineering guidance for designing and fabricating these panels for applications requiring combined axial and transverse loading, such as exterior walls and roof systems.

This publication is designed for: architects, engineers, designers, engineered wood manufacturers

The publication presents a complete design methodology based on recognized engineering principles, developed by the U.S. Forest Products Laboratory and verified through extensive testing. It covers structural behavior, material requirements, design calculations for various loading conditions, and detailed fabrication specifications.

Key sections include:

• Design of plywood sandwich panels

• Panel design for combined loading

• Fabrication of plywood sandwich panels

• Design example for plywood sandwich panels
