dc.description.abstractDue to the complexity of modern tall building structures, structural design following the traditional trial-and-error approach makes the design process extremely time-consuming and the resultant design uneconomic. This paper studies the feasibility in formulating the structural design problem as a minimization problem and solving it by numerical optimization algorithms. With the help of the numerical optimization algorithms, the trial-and-error design process can be carried out in a systematic and, even more important, automatic manner. In this study, the design process is formulated as the minimization of the total weight of the building under a series of constraints, which are designed to consider different design criteria. The considered design criteria include the strength, top and inter-storey drifts, frequency, and stability requirements specified in the British Standard and code of practice in Hong Kong. A large-scale building example is employed in the case study to illustrate the structural optimization design approach. The results of case study show that the structural optimization design approach provides a valuable tool for engineers to obtain a feasible and economical design even when the initial design violates some of the design criteria.-
