Abstract:Following an extensive literature study, a three-phase experimental an investigation was conducted using single A307 anchor bolts embeded in normal weight concrete and loaded quasi-statically in monotonic and reversed cyclic shear. All bolts were embedded sufficiently to develop the minimum specified tensile strength of the anchor steel. Based on the results of this and other investigations, expressions are presented for calculating the minimum critical edge difference at which an anchor embedded in plain concrete can develop its full strength in shear. Using 180 deg hairpins, reinforcing details were developed allowing an anchor to develop its full shear strength even when placed at less than that minimum critical edge distance. These details were found to be satisfactory under reversed cyclic as well as montonic shear. Procedures are presented for the design of anchor bolts lad studs under monotonic and reversed cyclic shear loads.
