When prestressing tendons are anchored in concrete having a compressive strength below 300kgf/cm^3, sufficient strength of an anchorage system should be confirmed by experiments. An ultimate strength design method of anchorage zone by employing estimation formulae of cracking strength and ultimate strength is proposed, which certifies safety of anchorage zone without experiments. By this method, reinforcement of anchorage zone of prestressing tendons of widely used systems, as BBR, SEEE, OSPA, VSL,etc., can be designed. Double reinforcement with both spiral and hoop reinforcing bars can be also designed. Cracking strength and ultimate strength of anchorage zone of prestressing tendons can not be evaluated by allowable strength design method employed in the present design standards, but they are obtained by the proposed method.
