Larger design forces now mandated in many areas due to the revised seismic and wind loads require design capacities for anchor bolts beyond any existing code values. Figure 5 shows typical stress-strain curves for the bolts used. The bolts were fabricated locally with USS threads from round bar stock and were not galvanized. Also, there are no provisions to prevent a brittle failure in the concrete as opposed to a ductile failure in the anchor bolt, as provided for with a probability-based limit states design or Load and Resistance Factor Design (LRFD) for steel. Anchor Bolts The anchor bolts were specified to be manufactured from ASTM A 7 steel with a min imum yield strength of 33 ksi. At that time, there exists a high bond stress at the first few inches of embedment. On a typical anchor bolt embedment, as a pre-load is placed upon the bolt, the bolt starts to shed its load to the concrete through its grip (bond) on the bolt. The embedment requirements for anchorage steel are not clearly defined by most codes and are left largely to the discretion of the design engineer. the anchor bolt extends down to near the anchor head of the bolt. In current practice the design of base plates is controlled by bearing restrictions on the concrete shear is transmitted to the concrete largely through anchor bolts, shear lugs or bars attached to the base plate and the tensile anchorage steel is generally proportioned only for direct stress.
