An optimality criteria algorithm for tall steel building design using commercial standard sections

Grierson and Chan (1991a, b) recently presented an efficient optimality criteria (OC) technique for the optimum design of large-scale tall steel building frameworks. In this paper, further developments of the technique are described concerning a detailed procedure to assign optimum discrete section sizes to structural members. A 60-storey, 7-bay framework example is presented to illustrate the practical applicability and efficiency of the proposed design optimization algorithm.Presented at NATO ASI Optimization of Large Structural Systems, Berchtesgaden, Germany, Sept. 23 – Oct. 4, 1991
