Optimum design problems are performed according to American Institute of Steel Construction-Allowable Stress Design (AISCASD) specifications. A computer program is developed in MATLAB interacting with SAP2000 OAPI (Open Application Programming Interface) to conduct optimization procedures. Optimum cross sections are selected from a specified list of 128W profiles taken from AISC. Two different braced planar frames taken from literature are carried out for stress, geometric size, displacement and inter-storey drift constraints. It is concluded that teaching-learning based optimization presents robust and applicable optimum solutions in multi-element structural problems. © 2016 Techno-Press, Ltd.eninfo:eu-repo/semantics/closedAccessMATLABSAP2000 OAPIOptimum designPlanar steel framesTeaching-learning based optimizationApplication programming interfaces (API)Application programsComputer programmingHeuristic algorithmsMATLABOptimizationSteel constructionStructural designStructural framesAmerican institute of steel constructionsMATLABSAP2000 OAPIMeta-heuristic search techniquesOpen application programming interfaceOptimum designsOptimum structural designPlanar steel framesTeaching-learning-based optimizationsStructural optimizationMATLABSAP2000 OAPIOptimum designPlanar steel framesTeaching-learning based optimizationApplication programming interfaces (API)Application programsComputer programmingHeuristic algorithmsMATLABOptimizationSteel constructionStructural designStructural framesAmerican institute of steel constructionsMATLABSAP2000 OAPIMeta-heuristic search techniquesOpen application programming interfaceOptimum designsOptimum structural designPlanar steel framesTeaching-learning-based optimizationsStructural optimizationOptimum design of braced steel frames via teaching learning based optimizationArticle22473374410.12989/scs.2016.22.4.7332-s2.0-85006515490Q1WOS:000391137400002Q1
