Abstract:
Article assists the designer in computing the concrete pullout strength for anchor bolt configurations. Nondimensionalized area coefficients are plotted for four patterns: 4-bolt, 6-bolt, and two 8-bolt patterns. The variables used are the center-to-center spacing of the bolts, the depth of embedment, and the diameter of the mechanical anchor heads. It is assumed that, in a particular pattern, all the anchor bolts are of the same type and have the same embedment length.
