Lateral Resistance of Anchor Bolts Installed in Concrete
Results of ninety-two lateral shear tests conducted on both 1 (25.4-mm) and 2-inch (50.8-mm) diameter anchor bolts installed in concrete to determine lateral resistance are reported. The parameters investigated were edge distance, type and configuration of reinforcement, method of installation, bolt diameter, bolt strength, and method of loading. Seventy-eight tests were performed by loading bolts in pure shear; bolts in the remaining fourteen tests were loaded in combined shear and bending. Ten of the specimens were subjected to low-cycle loading without stress reversal. Fourteen of the pure shear tests were conducted on pairs of 1-inch (25.4-mm) diameter bolts to determine the effect of group action. The most efficient method of anchor bolt installation tested utilized a metal cannister filled with mortar and reinforced with hairpin tiebacks. A bolt deflection of 0.05 inches (1.27 mm) measured near the concrete surface was used as the governing criterion for establishing yield load levels. Design curves based on this criterion are presented for various parametric combinations.
