“…4 (c) and (d) demonstrate the HRR of tests with 2 kg and 6 kg fuel mass, and it was found that the cracks were normally initiated in the steady stage. However, in enclosure fires, the incident thermal flux is directly proportional to time for the growing period of the fire [21]. As illustrated in Table 3, the critical heat flux was around 10 kW/m 2 for Pane 1, and its threshold value was 5.72 kW/m 2 .…”

The thermal resistance from the air gap and fire side glass pane was found to play a key role for the ambient side pane of the insulated glazing. Although both panes of the laminated glazing broke, it could be held together by the layer of gel, effectively avoiding the formation of a new vent. Numerical simulations were performed to investigate the heat transfer process through the glazing panels and the temperatures in the glazing were predicted well. Suggestions for glass fire resistance design are proposed.

“…As a result, thermal stresses develop increasingly due to temperature differences, and the glass pane will break and even fall out at a certain level. Experimental tests have been carried out to study glass breakage in fires using room calorimeters and bench-scale test facilities [1][2][3][4][5][6]. Gas and surface temperatures and heat fluxes for breaking glass were studied for numerous types of glass.…”

Abstract. This paper presents experimental and numerical studies of fire and smoke movement in the cavity of double-skin glass facades. The experimental tests were conducted using a two-storey rig with double-skin facade installed. Test results showed that double-layer of toughened glass panes broke when the temperatures reached about 600 • C-800 • C; the fire and smoke plume from the fire room were more likely to impede on the external skin in the cavity at the steady burning stage, and this could cause the external skin to break. The FDS model was employed to simulate one of the experimental tests and further used to study the effect of fire sources and cavity depths. Numerical modellings show good agreement when comparing the modelled temperatures with the measured temperatures next to the internal skins and external skins. For fully-developed fires in the modelling scenarios, the fire and smoke plume hit the external panes without any attaching to the internal panes. The fire and smoke plume could break the external skin but the internal skins are safe at low temperatures.

“…e issue of glass thermal cracking and fallout has been rst raised in 1980s by Emmons [51] and other researchers [52,53], while in the last decades, an increasing number of experiments have been carried out on small-scale specimens, single glass panes, or double glass panes variably supported, under the e ect of re or heat radiation (see, e.g., [54][55][56][57][58][59][60] …”

Architectural design concepts incorporating glass beams, panels, or generally load-carrying elements and sti eners for buildings, claddings, windows, and partitions are largely considered in modern high-rise constructions. A multitude of aspects, including motivations related to transparency, aesthetics, illumination, and energy conservation, progressively increased the use and interest for such a still rather innovative constructional material. However, compared to other traditional materials for buildings, standard glass is typically characterized by brittle behaviour and limited tensile resistance. e intrinsic properties of glass, moreover, together with typically limited thickness-to-size ratios for glazing elements, or the mutual interaction of glass components with adjacent constructional elements as a part of full assemblies they belong (i.e., xing systems, sealants, etc.), as well as the combination of mechanical and thermal phenomena, make glass structures highly vulnerable. Special safety design rules are hence required, especially under extreme loading conditions. In this review paper, a state of the art on structural glass systems exposed to re is presented. Careful consideration is paid for actual design methods and general regulations, as well as for existing research outcomes-both at the material and assembly levels-giving evidence of current challenges, issues, and developments.
