Double shearing of rebar steel and cable bolts for effective strata reinforcement

摘要

An experimental study was undertaken to examine the shearing behaviour of both steel rebar and hollow strand cable bolt across joints and shear planes. Double shearing testing using double shear box as shown below, were made on rebar steel and cable bolts in concrete blocks. Five steel rebar bolt types were used for the study. Three bolts were 22 mm core diameter bolt types with different profiles, the forth was 11 mm threaded bars and the fifth was a 12 mm construction bolt.
