"An experimental study on shear behaviour of fully grouted rock bolt un" by Saman Khaleghparast, Naj Aziz et al.
This paper aims to enhance the understanding of conventional rock bolt performance subjected to shear loading under static and in particular dynamic loading conditions. For this purpose, thirteen sets of static tests were undertaken using 16 mm smooth and 18 mm ribbed rock bolts aiming; 1) to examine the effect of internal confinement, and 2) to evaluate the energy absorption of the system subjected to static shear loading. The dynamic response of the conventional 18 mm ribbed rock bolt was assessed by using the drop hammer to generate high-intensity dynamic loading. The results showed that us...
