Further 'blind' tests were conducted of all 8 anchorages, and again the GRANIT system was used in order to diagnose the load.
The results shown below again exhibit very high accuracy.
Some of the higher loads are not diagnosed to within the target 10% error range, and this is due to damage incurred to the anchorage head due to the high stress levels. The tests showed that the bearing plate was not able to withstand loads above about 120kN, and above that level became increasingly damaged. In spite of this damage, the GRANIT system has still been able to diagnose the higher loads.
