Abstract The strength of a rockbolt is one of the key parameters for the design of ground support systems. However, published mechanical performance data by suppliers are usually limited to tensile strength and elongation. To provide additional performance measures, mechanical tests on four commercially available solid reinforcing bar rockbolts have been performed and analysed. In each of the cases, the rockbolts are marketed by the manufacturers as being similar and equivalent products. The mechanical tests have been developed to mimic five modes of failure that include tension, shear, torsion, and nut/thread interface. The results show significant variability in seemingly similarly marketed products. Recommendations are made for suppliers to provide additional testing results (torsion, shear and nut/thread capacity) as standard data within their product specification sheets. A summary of recommended design parameters is provided based on the test results.
