In this study, an algorithm is developed for the optimum design of the steel buildings. The optimum design problem is formulated according to LRFD-AISC. Design constraints include the displacement limitations, inter-story drift restrictions of multi-story frames, strength requirements for beams and beam-columns and geometric constraints. Teaching and learning based optimization (TLBO) technique, inspired by the interaction and outcome of teacher and learners, is employed to determine its optimum solution. The design algorithm developed selects optimum W sections for beams and columns of three dimensional steel frames so that aforementioned constraints are satisfied and the frame has the minimum weight. A large scale steel building has been designed by TLBO algorithm developed in order to test performance of the algorithm.
