FACET Consulting Engineers of Brisbane arranged the strength testing for Oz-Post to determine the bending strength.  

The Structures and Geometrics Testing Laboratory of The Department of Civil Engineering at The University of Queensland; a NATA accredited testing facility administered testing equipment, instrumentation and testing personnel.

The primary purpose of the testing was to establish the lateral bending strength of a variety of Oz-Post Oz-Spike’s in light to medium sandy and silty clay soil conditions. 

Receiving test data at the bottom end of the range of expected bending strength, presented a lower bound expectation and replicated the behaviour of the Oz-Post ground spike under the effect of wind loading and other horizontal loadings.

Dynamic Cone Penetrometer testing was undertaken at a representative number of points at each test site to provide for correlation between soil strength parameters and Oz-Spike™ bending strength test results.

Further information specific to these tests is available on request. 

A 5kN calibrated load cell was used to apply a horizontal load against a reaction frame. Loading was applied at approximately 1kN/minute to failure. 

From the test data obtained, suitable posts for particular applications could be established by calculation to suit particular Oz-Post supports in these soil strength conditions.
