The Metalpla program has been used to carry out the calculations for the doctoral thesis “Idoneidad del grado de rigidez de las uniones en pórticos metálicos de naves a dos aguas en edificación agroindustrial” (Suitability of the degree of connection stiffness in double-pitched steel portal frames for agro-industrial buildings), recently defended on 19 January 2016 at the Universidad Politécnica de Madrid. In this thesis, more than 46,000 double-pitched steel portal frames with different geometries and loads were designed. The program optimised these structures taking into account the stiffness of their connections, as well as the automatic determination of the buckling coefficient of the members.
