This study proposes a new analytical\nmodel to predict shear stress in a fully encapsulated\nrock bolt in jointed rocks. The main characteristics of\nthe analytical model consider the bolt profile and jump\nplane under pull test conditions. The performance of\nthe proposed analytical model, for different bolt\nprofile configurations, is validated by ANSYS software\nand field. The results show there is a good\nagreement between analytical and numerical methods.\nStudies indicate that the rate of shear stress from the\nbolt to the rock exponentially decayed. This exponential\nreduction in shear stress is dependent on the bolt\ncharacteristics such as: rib height, rib spacing, rib\nwidth and resin thickness, material and joint\nproperties.
