Random number sequences on the optimum design of steel
castellated beams have an important effect in the minimum weight design. In the present research, this effect is
investigated using an optimum design algorithm which is based on a recently
developed improved harmony search method (IHS). Harmony search optimizer is a simulator
of musically pleasing that is used to realize the experience of a musician for
searching pleasing harmony, which is the musically
performance process based numerical optimization technique. The
minimum weights of both beams are taken as the objective functions while the
design constraints are respectively implemented from The Steel Construction
Institute Publication Numbers 5. The
design methods adopted in these publications are consistent with BS5950 parts.
The formulation of the design problem considering the limitations of the above
mentioned turns out to be a discrete programming problem. The design algorithms
based on the technique select the optimum Universal Beam sections, dimensional
properties of hexagonal holes and total number of openings along the beam as
design variables.
