Effect of Random Number Sequences On The Optimum Design of Castellated Beams With Improved Harmony Search Method

摘要

Random number sequences on the optimum design of steelcastellated beams have an important effect in the minimum weight design. In the present research, this effect isinvestigated using an optimum design algorithm which is based on a recentlydeveloped improved harmony search method (IHS). Harmony search optimizer is a simulatorof musically pleasing that is used to realize the experience of a musician forsearching pleasing harmony, which is the musicallyperformance process based numerical optimization technique. Theminimum weights of both beams are taken as the objective functions while thedesign constraints are respectively implemented from The Steel ConstructionInstitute Publication Numbers 5. Thedesign methods adopted in these publications are consistent with BS5950 parts.The formulation of the design problem considering the limitations of the abovementioned turns out to be a discrete programming problem. The design algorithmsbased on the technique select the optimum Universal Beam sections, dimensionalproperties of hexagonal holes and total number of openings along the beam asdesign variables.
