ABSTRACT

Halls made of lightweight steel elements have been known for years. The main reason for using steel in hall structures is easy and quick assembly, largely independent of the prevailing weather conditions and the possibility of full prefabrication. The problem occurs when we have halls with a significant span, and the deflections of the beams become significant. An alternative may be, for example, roofs in the form of trusses or replacing prismatic cross-sections with cross-sections with belts-tapered or web-tapered. However, the question arises about how tapered cross-sections in the hall structure will affect steel consumption if the hall is located in a seismic area. Thus, the major aim of this paper was a numerical analysis of a lightweight steel hall with prismatic and tapered cross-section elements. The analysis was performed in the Dlubal RFEM program using the finite element method.
