This article concerns the use of structural glass in the adaptive reuse of historic facilities using glass beams as structural elements in steel-glass roofs. More and more often, glass is increasingly being used as a structural material. This fact provides new design possibilities in the adaptation of historic buildings due to the neutral perception of glass and, at the same time, offers the possibility of distinguishing modern structural elements in the historic fabric. The use of structural glass is, however, associated with limited spans of structural elements. For larger spans, solutions of mixed materials are proposed, which are exemplified by steel-glass roofings. Based on selected examples, steel-glass systems with the use of glass beams are characterised. The strength of glass as a structural material is discussed. The main approaches in the design of glass beams with the lateral-torsional buckling phenomenon are indicated.
The article discusses the characteristics of steel-glass construction elements. Characteristics of glass used in these elements are given. Behaviour of them is presented, as well as a design approach, in compare to results with similar pure steel elements.
The article presents an overview of research and applications of glass as structural material, cooperating with other materials: steel, timber, glass or carbon fibre composites. It presents examples of reinforced glass structural elements as well as complex composite components. The most promising seem to be beams with a glass web and flanges made of timber (preferably laminated). In the near future, the author plans to conduct the laboratory research on hybrid timber-glass beams on the full-scale models.

W artykule przedstawiono przegląd badań i zastosowań szkła jako materiału konstrukcyjnego, współpracującego z innymi materiałami - stalą, drewnem, kompozytami zbrojonymi włóknem szklanym lub węglowym. Przedstawiono zarówno przykłady elementów ze szkła zbrojonego, jak również wielomateriałowe elementy zespolone. Najbardziej obiecujące wydają się tutaj być belki ze środnikiem szklanym i pasami z drewna (najlepiej klejonego). W niedalekiej przyszłości autor przewiduje objęcie tego typu elementów badaniami w skali naturalnej.
