Abstract: | The load transfer capacity and failure mechanism of a fully grouted bolt installed across a joint in shear is investigated,
both experimentally and numerically, in five types of bolt. The double-shearing testing of bolts were studied in concrete
blocks of 20, 40 and 100 MPa strengths, subjected to different pretension loads of 0, 5, 10, 20, 50 and 80 KN, respectively.
The parameters examined include: shear resistance, shear displacement, induced strains and stresses during the bolt-bending
process, and its ultimate failure across the sheared joint planes. The conclusions drawn from the study were that the strength
of the concrete, bolt profile configuration and bolt pretension load played a significant influence on the shear resistance,
shear displacement and failure mechanism of the reinforced medium. Experimental and numerical simulations showed that the
failure occurs as a result of the induced axial and shear stresses acting between the hinge point distances in the vicinity
of the shear joint plane. |
