REPORT ON STRUCTURE LOAD BEARING TEST Compiled By Kosie Smith 29 February 2016 1
1. CONSTRUCTION • An I beam frame was constructed and mounted on 8 square tubing legs at a height of 1. 5 m (5 ft). • The frame size is 3 m x 2. 8 m (9’ 10” x 9’ 2”). • The center of each side is anchored to prevent the inward bowing of the beams. 2
• 2. The Extreme 32 net was secured by Keder railings on all sides. Two sides are fixed while the other two sides are adjustable to tension the net. MATERIAL SPECIFICATIONS • I Beams 100 x 200 x 8 mm (4” x 8” x 5/16”) • Angle Iron 50 x 5 mm (2” x 3/16”) • Square Tubing 76 x 5 mm (3” x 3/16”) • Keder Railing 16 mm with 10 mm PVC Cord 3
3. LOADING THE FRAME • The frame was loaded with bags of HDPE granules weighing 25 kg (55 lb) each. 4
• At a load of 4 000 kg (8 800 lb) we noticed that the top flange of the I beam was bending inwards due to the load. 5
• • An additional anchor was secured to the top flange to prevent the bowing. The net was then cut to see whether it would tear under the load. Holes were cut on the weft and warp sides, and amazingly it did not tear any further. 6
• • We continued to load the net to 5000 kg (11 000 lb). At this point, it was risky for the people loading more material onto the net. 7
• The net was then cut to see whether it would tear under the load. Holes were cut on the weft and warp sides, and amazingly it did not tear any further. 8

3. CONCLUSION • It is clear that the net can withstand a load of that nature. • Even when the net was cut, it did not tear. • The Keder railings did not open. Will a structure construction company ever erect a structure to these specifications? This is proof that the net will almost always outlast the structure, if properly secured and tensioned. 10
