Testing a Composite Stand to DESTRUCTION

Testing a Composite Stand to DESTRUCTION, here are the facts! Wayne Crowell the Manager of Structural Testing Services at University Southern Queensland successfully tested our latest stand designs to comply with the requirements of AS 2538:2016. Firstly, to rate a 25t capacity x 1200mm stand with an ultimate load of 75t and a structural integrity (side load) test of 38t. Secondly, a 35t capacity x 1200mm stand with an ultimate load of 105t and a structural integrity (side load) test of 53t. Passing both of these tests we decide to test the now rated 35t capacity x 1200mm stand to destruction. Pictured in the graph which is a data log of the test process, partial failure marked by the red arrow at 1440kN (140t). One of the stands columns (it has two) has failed at this point. The load bearing ability of the stand falls away quickly, however it stabilises at 600kN (60t). We continue to apply load back up to and above the initial failure. It reaches 1600kN (160t) before it fails the final composite column. However, as you can see in the data/graph, once it stabilises the stand continues to support 600kn (60t).
