Abstract
The writers recently created a fuzzy discrete multicriteria optimization model for automated design of large steel structures subjected to the actual constraints of commonly used design codes. In this work, the model is used to perform a comparative study of optimum designs of steel high rise building structures using AISC allowable stress design and load and resistance factor design (LRFD) codes. Results are presented for two large structures, a 36-story space moment-resisting frame with cross bracings and a 144-story super high-rise building structure with over 20,000 members. LRFD code results in the cost savings in the range of 3.0–6.9% for the 36-story steel structure and 1.7–4.3% for the 144-story steel structure. When serviceability (stiffness) is more of a controlling factor, the LRFD code in general yields a much smaller advantage for weight savings.
