Experimental Investigation of Anchor Bolts under Shear
Publication: Journal of Structural Engineering
Volume 116, Issue 4
Abstract
An experimental investigation of anchor bolts embedded in unrein‐forced concrete, monotonically loaded in shear is described. The anchor bolts are embedded sufficiently to develop the minimum tensile strength of the bolt steel. Pairs of anchor bolts (double‐bolt anchorages) with varying spacings and edge distances are loaded in shear in the direction perpendicular to the line of the bolts. Single‐bolt anchorages are also tested in shear with varying edge distances and compared with the results of the double‐bolt anchorage tests. Concrete failure with wedge cone is observed in most cases. The effects of the edge distance and bolt spacing on the shear resistance of anchor bolts are discussed. The ACI Committee 349 shear resistance formula has been found to give good estimates of the single‐bolt anchorage tests. However, the concept of wedge cone interaction, commonly used for calculating the tensile pull‐out capacity of anchor bolt groups, is found not directly applicable to double‐bolt anchorages under shear. The influence of the support conditions of the concrete test blocks on anchor bolt shear strengths is also investigated.
