Architectural design concepts incorporating glass beams, panels, or generally load-carrying elements and stiffeners for buildings,\ncladdings, windows, and partitions are largely considered in modern high-rise constructions. A multitude of aspects, including\nmotivations related to transparency, aesthetics, illumination, and energy conservation, progressively increased the use and interest\nfor such a still rather innovative constructional material. However, compared to other traditional materials for buildings, standard\nglass is typically characterized by brittle behaviour and limited tensile resistance. The intrinsic properties of glass, moreover,\ntogether with typically limited thickness-to-size ratios for glazing elements, or the mutual interaction of glass components with\nadjacent constructional elements as a part of full assemblies they belong (i.e., fixing systems, sealants, etc.), as well as the\ncombination of mechanical and thermal phenomena, make glass structures highly vulnerable. Special safety design rules are\nhence required, especially under extreme loading conditions. In this review paper, a state of the art on structural glass systems\nexposed to fire is presented. Careful consideration is paid for actual design methods and general regulations, as well as for\nexisting research outcomesââ?¬â?both at the material and assembly levelsââ?¬â?giving evidence of current challenges, issues, and\ndevelopments.
