Ultimate load values in 000 and 000 psi stone aggregate concrete. Ultimate loads are indicated for the embedment shown in the Embedment in Concrete column. Performance values are based on minimum Grade 0 reinforcing bar. The use of lower strength rods will result in lower ultimate tension and shear loads. SHEAR DATA: Provided the distance from the rebar to the edge of the concrete member exceeds.5 times the embedment depth of the rebar, calculate the ultimate shear load for the rebar anchorage as 0% of the ultimate tensile strength of the rebar. Combined Tension and Shear Loading for Adhesive Anchors Allowable loads for anchors under tension and shear loading at the same time (combined loading) will be lower than the allowable loads for anchors subjected to 00% tension or 00% shear. Use the following equation to evaluate anchors in combined loading conditions: ( ) ( ) Na 5/ + Va 5/ Na = Applied Service Tension Load Va = Applied Service Shear Load Ns Vs Ns = Allowable Tension Load Vs = Allowable Shear Load
