Özet
The harmony search method based optimum design algorithm is presented for geometrically non-linear semi-rigid steel frames. Harmony search method is recently developed metaheuristic algorithm which simulates the process of producing a Musical performance. The optimum design algorithm arms at obtaining minimum weight steel ftarnes by selecting from standard set ol'steel Sections Such ZIS E-uropeall wide flange beams (HE sections). Strength constraints of Turkish Building Code flor Steel Structures (TS648) specification and displacement constraints were used in the optimum design formulation. The optimum design algorithm takes into account both the geometric non-linearity of the frame members and the semi-rigid behaviour of the be,beam-to-column Connections. The Frye-Morris polynomial model is used to calculate the momentrotation relation of beam-to-column connections. The ronustness of harmony search algorithm, ill comparison with genetic algorithms, is verified with two benchmark examples. The comparisons revealed that tile harmony search algorithm yielded not Only weight steel frames but also required less computational effort for the presented examples.
