“…During the course of the fires, the integrity of the double glazing units were retained except for the latter part of the tests for the 1.0m square trays. In the case of the single glazing tests, although extensive cracks formed in the glass, glass fallout was considerably delayed for the smaller tray sizes [6]. However the data was only taken for periods preceding catastrophic glazing failure, generally up to the peak energy release period.…”

“…Furthermore, the results of studies conducted elsewhere in corner and sidewall geometries have been interpreted in [4] to imply much greater differences in the entrainment of air into the corner and sidewall geometries than suggested in [3]. Recent analysis of studies conducted at FireSERT in well instrumented full scale (modified ISO scale room) and third scale enclosures [5,6,7] provided an opportunity to study the validity and generality of the MQH correlation and the associated MW modifications. The studies encompassed fire spread over combustible linings [5] and of discrete liquid pool fires used in glazing related studies.…”

“…The studies encompassed fire spread over combustible linings [5] and of discrete liquid pool fires used in glazing related studies. In the latter studies, the square fuel trays used ranged in size from 0.5m to 1.0m [6]. This paper presents an initial analysis of the results of the MQH correlation deduced for discrete pool fire sources located in near corner and centre configurations in enclosures lined with non combustible Fiberboard (Duraboard Tm) surfaces with fully opened and half opened vent widths.…”

An experimental study of liquid pool fires was undertaken in the corner and centre fire geometries. An Industrial Methylated Spirits fuel placed in square trays and elevated from the floor was used in the study. The fuel trays ranged in size from a 0.2m tray which was used in a 1/3 scale test enclosure to 0.5-1.0m trays used in an ISO sized room. Measured, well mixed ceiling gas temperatures and energy release rates were correlated with two dimensionless groups as used in the well known McCaffrey, Quintiere, Harkleroad (MQH) correlation. An initial interrogation of the MQH correlation suggests that the modification to the MQH correlation suggested by Mowrer and Williamson for the corner fire geometry is satisfactory. In the case of the centre room fires, correlation of the data suggested a proportionality factor C T which was at the upper limit of the data correlation shown in the original MQH work. This result may be attributable to intermittent flames approaching the ceiling for these tests where quality data was only available tests with the doorway at half width and for large fuel trays. The paper addresses key factors that need further investigation for validating and refining the MQH correlation(s).

“…Experimental work by Hassani et al [16] suggests that the stress fields are significantly different for windows exposed to a two-layer fire environment over their height. The increasing use of large windows in modern buildings means that windows will often be exposed to a hot upper layer and a cooler lower layer during the development of a fire.…”

SUMMARYThe objective of this study is to directly measure the critical breakage stress for glass through mechanical tensile experiments based on MTS 810 apparatus. Two series of experiments were, respectively, conducted under the condition with a room temperature (25 • C) and a hot environment (200 • C) for float glass. The results show that the critical breakage stresses of 6, 8, 10 and 12 mm float glass are, respectively, 74, 127, 158 and 198% larger than that of 4 mm float glass under the condition with a room temperature (25 • C). Similarly, the critical breakage stresses of 6, 10 and 12 mm float glass are, respectively, 29, 72 and 93% larger than 4 mm glass in the hot environment (200 • C). In addition, through the comparison between the two series of experiments, it suggests that the critical breakage stresses of 6, 8, 10 and 12 mm thick float glass in a hot environment are, respectively, 7, 48, 16 and 19% smaller than that in a room temperature. It is suggested that the measured critical breakage stress of float glass here is relatively smaller than those in the previous measurements.
