Cost optimization and sensitivity analysis of composite beams
Abstract: This study presents
exact solution analysis for the cost optimization of Composite Beams (CB) based
on the Load and Resistance Factor Design (LRFD) specifications. Matlab code
formulation is applied to analysis of sensitivity for various parameters such
as cost of concrete, steel beam, span length, concrete slab thickness,
compressive strength of concrete, steel beams space and shear connectors on CB.
Almost 20 thousands design were analysed to obtain various contour which be
found that it is feasible, efficient and effective and capable in optimization
of composite beam designs.
The obtained results represent that many of the contour are capable by
achieving substantial cost savings for composite materials. Therefore, the
analysis can be developed for practical designs to structural designers. A
parametric study was also conducted to investigate the effects of IPE, IPB, INP
profiles, UNP size and thickness of slabs and beam length on the cost
optimization of CB.
