This paper presents the analysis of the spatial prismatic sloped overlay of irregular shape with a spherical surface upon. This bearing steel structure is under a dead‐load of a framed glass packet and under snow. Mathematical model of prism and spheroid geometry is developed. Construction geometry of a rectangularly profiled pipe and snow pressure is modelled in finite elements, using special software is developed by authors. This software is designed for the evaluation of glass structures and is easily adopted for a data exchange with commercial software. Computer aided design of the overlay and structure stress‐deformation analysis is realized by ANSYS.

“…minimum volume (weight) or minimum cost (Prager 1955;Skaržauskas et al 2005;Kalanta et al 2009;Šešok and Belevičius 2008). Engineering development in the field of optimal structural design requires some theoretical and practical knowledge, including the fundamentals of structural mechanics, structural design standards (STR 2.05.08;EN 1993EN -1-1: 2005 and, finally, modern information technologies.…”

Abstract. The improved mathematical model of steel frame structures' design is created. The loading is simple, and plastic strains are evaluated. Energy principles of deformable body mechanics and mathematical programming theory are employed. Equilibrium finite elements with interpolation functions of internal forces are used for discretization. The elements are designed using HE, IPE, RHS steel profile assortments and considering dispersion of geometrical characteristics of profile assortment sets. Optimal design of steel structures is realized by using the experimental tool system JWM SAOSYS Toolbox v0.42, which was created by the authors in MATLAB environment. SAOSYS architecture operates with objectoriented finite elements pseudo-polymorphously. The possibilities of this system are demonstrated by considering a numerical example of optimal design of industrial building frame with strength and stiffness constraints. The assumption of small displacements is adopted for computations.
