A procedure is proposed leading to an optimal detailed design of reinforced concrete members. The general scheme followed is that of a multi-criterion design optimization. The method synthesizes the information from the cross-sectional level, to the member level and finally, to a group of members where the detailed design of the whole group is decided. At the cross-sectional level, the required reinforcement in cm(2) is converted into reinforcing bars of all possible diameters. At the member and/or group of members level, a number of lists that contain different design scenarios are generated. The method of objective weighting is applied to a multi-criterion objective function, which represents a compromise of the 'minimum weight', 'maximum uniformity' and 'minimum number of reinforcing bars' criteria. By varying the weighting factors, it is possible to generate the Pareto optimal set of the problem. The performance of the system is illustrated with a number of examples. The same building is designed using different weighting factors in the multi-criterion objective. The variation of the detailed designs is discussed and certain values for the weighting factors are recommended. Copyright (C) 1996 Civil-Comp Limited and Elsevier Science Limited.
