Experimental Study of Post-Installed Anchors Under Combined Shear and Tension Loading
The behavior of post-installed anchors subjected to static combined shear and tension loads was studied experimentally. Twenty-four 1 in. diameter wedge-type expansion anchors were tested in uncracked concrete. Anchors were not preloaded and were located sufficiently far from the edge of the concrete specimens. There were two types of shear failures: steel fracture near the bottom of the anchor at the tapered section for anchors with shallow embedment depths and steel fracture along the shank for more deeply-embedded anchors. Two types of tension failures occurred: steel tensile failure at the threads and cone-shaped tensile failure of the concrete. For specimens failing in shear, anchor capacity depended mainly on embedment depth. A limiting capacity was reached at an embedment depth of approximately 6 in. when steel failure controlled. Anchor deformation was influenced by both load angle and embedment depth.
