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

Abstract

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.

A new hybrid Harris hawks optimization (HHO) and particle swarm optimization (PSO) algorithm for the design of castellated beams

“…Kaveh et al employed a VBS algorithm as a meta-heuristic algorithm to optimize composite steel deck slabs and supporting castellated beams consisting of interior beams, edge beams, and girders (Kaveh & Fakoor, 2021 ). Erdal et al, ( 2016 ) investigated the influence of Random number sequences in the HS algorithm on the optimum design of steel castellated beams. Kaveh applied the Tug of War optimization algorithm for designing castellated beams (Kaveh, 2017 ).…”

Numerical analysis on stress and displacement of tapered cantilever castellated steel beam with circular openings

“…Castellated steel beams are a type of beam made by reforming the shape of the steel beam's section into a half with a particular pattern and by reconnecting those parts into a new steel beam. This doubles the steel beam's moment of inertia while maintaining the same volume [5]. The shape of web openings can also be variated, depending on its function and aesthetic considerations.…”
