STAAD.Pro is capable of performing concrete design based on the Japan code AIJ 1991 Architectural Institute of Japan Standards for Structural Calculation of Steel Reinforced Concrete Structures. Design for a member involves calculation of the amount of reinforcement required for the member. Calculations are based on the user specified properties and the member forces obtained from the analysis. In addition, the details regarding placement of the reinforcement on the cross section are also reported in the output.
