| contents | DESIGN OPTIMIZATION OF TRIPOD TRUSS: SLP APPROACH Goteti Chaitanya Reddy Sreenivasulu Administración y Contabilidad height mean diameter buckling stress Sequential Linear programming The efficiency of sequential linear programming technique in optimizing nonlinear constrained structural optimization problems is studied in this paper considering tripod truss structure as a case study. The problem is formulated for minimum weight considering localized buckling stress, Euler buckling stress and direct compressive stress as constraints. The axial force in each of the members of the truss due to payload is estimated using vector mechanics. The structure is optimized considering mean diameter and payload height as design variables. The weight of the truss got reduced by 20.51%.The optimum values of design variables obtained are compared with the values obtained using graphical method. The optimum values of objective functions obtained using both the approaches are in reasonable agreement with a mere 5.17% variation. 2015 artículo científico 2236-269X https://www.redalyc.org/articulo.oa?id=449544329006 en http://www.redalyc.org/revista.oa?id=4495 Independent Journal of Management & Production application/pdf Instituto Federal de Educação, Ciência e Tecnologia de São Paulo Independent Journal of Management & Production (Brasil) Num.1 Vol.6 |
