Vk. Koumousis et al., DETAILED DESIGN OF REINFORCED-CONCRETE BUILDINGS USING LOGIC PROGRAMMING, Advances in engineering software, 25(2-3), 1996, pp. 161-176
A procedure is proposed leading to an optimal detailed design of reinf
orced 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 deci
ded. 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 d
ifferent design scenarios are generated. The method of objective weigh
ting is applied to a multi-criterion objective function, which represe
nts a compromise of the 'minimum weight', 'maximum uniformity' and 'mi
nimum number of reinforcing bars' criteria. By varying the weighting f
actors, it is possible to generate the Pareto optimal set of the probl
em. The performance of the system is illustrated with a number of exam
ples. The same building is designed using different weighting factors
in the multi-criterion objective. The variation of the detailed design
s is discussed and certain values for the weighting factors are recomm
ended. Copyright (C) 1996 Civil-Comp Limited and Elsevier Science Limi
