Load transfer is considered an important attribute of fully encapsulated rockbolts in terms of enhancing ground support. Greater benefit is gained in a system that can achieve a high rate of load transfer. Several models have been developed in an attempt to characterise the nature of load transfer. A test program was conducted that examined two methods of applying force to a rockbolt that might account for the difference between the models. It was found that with all other factors held constant, the nature of load transfer depended on the method of loading. The pull out test arrangement of applying load to a rockbolt resulted in a different load transfer function in rock compared to that which resulted from loads induced through bed separation.
