What happens here
With the composite decking secured over supports at a 16-inch on-center spacing, a hydraulic jack is positioned underneath the center of this span. The presenter manually operates the pump handle of the hydraulic jack, applying upward force to the decking. A pressure gauge, connected to the hydraulic system, indicates the increasing load. The decking visibly deflects and ultimately fractures before the applied force reaches 1 ton.
Goal: Measure the load-bearing capacity of composite decking when framed at 16 inches on-center.
Tools and materials
- Hydraulic Jack — Applying controlled upward force to the composite decking
- Pressure Gauge — Measuring the force exerted by the hydraulic jack
- Safety Glasses — Protecting eyes from debris during material failure
- Wooden Test Frame N/A — Supporting the composite decking at 16-inch on-center spacing
- Composite Decking — The material under test for this configuration
