The goal of this project is to improve upon current flat panel products by developing a shallow corrugated panel that could require only minor changes to current manufacturing and construction methods. The corrugated panel plus an underlayment sheet are about the same weight as current single or double layer floor sheathing systems and can span from 32 to 48 inches with improved strength and stiffness.

Design studies using computer models were used to identify the most promising corrugated panel configuration based on structural performance and compatibility with construction practices. Molding trials on small specimens provided data for full size molding dies and allowed testing of localized structural properties. Production of full sized, 48"x 96" corrugated panels followed. Panel testing has been done to simulate floor loading during construction, without a top underlayment layer, and during occupancy, with an underlayment over the panel. These tests simulated actual load conditions and construction details.

Composite action specimens were tested for load sharing between the corrugated deck system and the supporting joist. A mock up floor system will be constructed and tested for deflection, vibration, and overall system behavior. A limited number of specimens will be subjected to long term loading to evaluate creep deflection characteristics. The results of the project should provide a clear indication of whether corrugated panels are a concept worthy of further development by the forest products community.
