“…Fig. 2 shows a cross section and the dimensions of the specimens, which are identical to the specimens tested by Louter et al (2016Louter et al ( & 2021 and by Sturkenboom (2018). The specimens consisted of laminated glass specimen made of three glass panes of the same glass type with a thickness of 10 mm each.…”

“…The upcoming research project at TU Dresden will develop a method to protect the surfaces and the edges of the glass beam without limiting its transparency. Additionally, FE-simulations like in Louter et al (2021) will be used to examine the heat flow through the glass panes of the laminated glass beam. In addition, FE simulations will be used to pre-select materials and setups before the tests will be carried out.…”

“…Early studies, by Veer et al (2001) and Bokel et al (2003) examined the fire resistance of small glass beams with a spot load of exposed fire. In later research, Louter et al (2016) and Louter et al (2021) examined explicitly the load-bearing behaviour of glass beams completely exposed to fire. Very similar tests were carried out by Sturkenboom (2018).…”

All-glass structures have become increasingly popular with architects and builders in recent years. Glass surfaces are becoming larger and more impressive, while connections are being decreased to obtain maximum transparency. The supporting structure of glass facades, glass roofs or walk-on glazing is mostly made of metal. One of the reasons for this are the fire protection requirements. To increase the overall transparency load-bearing glass structures have recently been given more attention. However, their use is currently still limited due to the concerns about glass performance in case of fire. Within a research study at TU Dresden load-bearing tests in a furnace were carried out to examine the load-bearing behaviour of glass beams exposed to fire. Different glass types and interlayer materials were tested with varying loads. This study provides a closer look at fire performance of glass beams and proposes further examinations to increase the load-bearing capacity in case of fire.

PurposeUnderstanding the structural performance of external glass curtain walls (façades) during fire exposure is critical for the safety of the occupants as their failure can lead to fire spread throughout the entire building. This concern is magnified by the recent increase in fire incidents and wildfires. This paper presents the first simplified technique to model single-skin façades during fire exposure and then utilizes it to examine the structural behaviour of vertical, inclined and oversized façade panels.Design/methodology/approachThe proposed technique is based on conducting simplified heat transfer calculations and then utilizing a widely used structural analysis software program to analyze the façade. Validation for the proposed technique with reference to available experimental and numerical studies by others is presented. A parametric study is then conducted to assess the structural performance of different glass façade systems during exposure to fire.FindingsThe proposed technique was found to provide accurate predictions of the structural performance of glass façades during fire exposure. The structural performance of inclined façade systems during fire exposure was found to be superior to vertical and oversized façade systems.Originality/valueThis research paper is the first to provide a simplified technique that can be utilized to model single-skin facades under fire. The presented technique along with the conducted parametric study will improve the understanding of the fire behaviour of single-skin glass facades, which will lead to safer applications.
