    load transfer in bolt bending
     
    load transfer is a basic aspect of reinforcement system behaviour, which has to be understood deeply in order to get a proper stability in surface and underground excavations.in terms of load transfer concept some parameters were studied such as different bolt profile, which has great influnce in transferring load from bolt through the resin to rock, strength of material and confining pressure at shear joint interface which was applied as pretensioning in bolt.also these parameters were evaluated by 3d numerical simulation.it was found that strength of material; bolt profile and pretensioning have significant influence on load transfer.
