Abstract

Forecasting of the ultimate resistance of steel beams subjected to concentrated loads using data mining techniques M. F. ~antos', H. ~uintela' & P. cmz2 1 Department of Information Systems, University of Minho, Portugal 2 Department of Civil Engineering, University of Minho, Portugal Abstract In the conception and design of civil engineering structures several factors should be considered: aesthetics, functionality, deformability, durability, resistance and cost. In general, that exercise is conditioned to the search of the safest solution at low cost. This concern, associated to the evolution of the materials' properties and of the computational tools, has been leading to the use of more and more refined design methods. In the special case of steel structures with very slender sections, the error presented by the current design formulas to forecasting the ultimate resistance of steel beams subjected to concentrated loads is significant, due to: the influence of several independent parameters
