ULTIMATE CAPACITY OF POST-INSTALLED ANCHOR BOLT UNDER STATIC SHEAR, TENSION AND THE COMBINED SHEAR AND TENSION LOADS

摘要

This paper describes the ultimate load capacities of typical post-installed anchor bolts under static tension, shear and combined tension and shear (combination) loads. The static loading test applying tension, shear, and combination loads was carried out on post-installed anchor bolts, such as resin-anchor bolt, and two types of mechanical anchor bo undercut type and sleeve-expansion type. Based on the test results, the equations currently used to calculate the ultimate allowable loading capacity of post-installed anchor bolts were investigated to establish the confidence level. Particular attention was paid to the ultimate load carrying capacities for combinated loads.
