The new versions of the EN 1993-1-1 (EC3-1-1) and the EN 1993-1-5 (EC3-1-5) standards have introduced the general method designing beam-column structures; see [1] and [2]. The design method requires 3D geometric model and finite element analysis. In a series of papers we present this general design approach. The parts of the series are the following:

The portal frames composed of tapered welded I-shaped structural members play important roles in the industrial buildings. The application of the relatively thin plates and the optimized fabrication makes these structures being competitive against the light truss structures at least in the range of 24–36 meters span. Competition has resulted in lesser selfweights using thin plated slender cross-sections, which are sensitive to local buckling. However, the development of structures concerning local buckling was delayed in Hungary by the conservative specifications of the MSz 15024 standard. The application of the new EN 1993 standard may cause radical development in the design of tapered structural elements with relatively thin plates. This paper introduces the methods as well as the advantages of the new design methodology.
