Intumescent flame-retardant coating (IFRC) provides a protective barrier to heat and mass transfer for the most efficient utilization of a wide variety of passive fire protection systems at the recent development. This article highlights the fire-resistance, physical, chemical, mechanical, and thermal properties of the IFRC using a Bunsen burner, furnace, Scanning Electron Microscope, freeze-thaw stability test, Instron Micro Tester, and thermogravimetric analysis (TGA) test. The five IFRC formulations were mixed with vermiculite and perlite for the fabrication of fire-resistant timber door prototypes in this research project. Additionally, the best fire-resistance performance of the fire-rated door prototype was selected and compared with a commercial prototype under the fire endurance test. An inventive fire-rated door prototype (P2), with a low density of 636.45 kg/m3, showed an outstanding fire-resistance rating performance, resulting in temperature reduction by up to 54.9 °C, as compared with that of the commercial prototype. Significantly, a novel fire-rated timber door prototype with the addition of formulating intumescent coating has proven to be efficient in preventing fires and maintaining its integrity by surviving a fire resistance period of 2 h.

Abstract : A series of standard fire-resistance tests were carried out to study the fire performance, failure modes and fire-resistance ratings of glulam beams. The test results showed that these glulam beams performed well during the tests, and the fire-resistance rating requirements can be achieved as expected. The study has provided necessary knowledge and experimental data for the determination of fire-resistance performance of glulam beams in the fire code of China.

Material strength is one of the most important factors in designing a building. For this reason, many structural steel manufacturers have been trying to develop it. In Korea, SM 570 is one high structural steel that has many merits such as longer span and reduction of construction cost for steel works. However, the fire resistance performance of H-section made of SM 570 has not been evaluated. Especially, in high-rise steel building that can be built with various joint systems like hinged to hinge, hinge to fixed, and fixed to fixed. However, the performance of fire resistant is limited. In this paper, to evaluate the fire resistance of H-section made of SM 570, the advanced fire design was conducted using regressive equation of the mechanical and thermal properties at high temperature, compared with those made of an ordinary structural steel, SS 400. The facts show that hinge to hinge had the lowest load bearing capacity at high temperature. Therefore, to keep the same fire resistance with other types boundary conditions, the more passive fire materials are required.

Fire-resistance performance experiments with static loading-fire are investigated about two carbon fiber sheet (CFS) shear strengthened reinforced concrete (RC) beams exposed to the ISO834 standard fire. Shear strengthened RC beams are wrapped with fire insulation material- thick painted fire retardant coatings. Relationship between measure points’ temperature and time are achieved. The results suggest that: the ratio of shear-span is the main factor to fire-resistance rating and failure modes of CFS shear strengthened RC beams in fire; shear-failure fire-resistance rating are increased by thickening fire insulation to shear strengthened RC beams. A computer program is developed to calculate the temperature fields of fire insulated concrete beams shear strengthened with CFS coated thick fireproof material. This program is validated comparing with experimental results. Researches can give a supplement to produce overall fire-resistance factors of CFS shear strengthened reinforced concrete beams at high temperatures.

As buildings are growing higher and larger, more composite structures have been used. However, the steel member used for composite structure tends to rapidly lose its strength at elevated temperatures. For this reason, it is required to apply a fire resistance mechanism, but it is difficult to implement because of the cost and technical limitations in the case of fire-resistant paint. In case of fireproof spray coat, scattering phenomena, poor work conditions for wet application, and construction delay are the main challenges to be addressed. In this study, a full-scale fire resistance test of non-fire resistant cladding column was conducted in accordance with KS F 2257-7. According to the test results, the specimens CC-01, CC-02, and CC-03 failed to meet the requirements for a 3-hour fire resistance rating because of the joint deformation and less cover thickness, while CC-04, CC-05, and CC-06 with increased thickness and reinforced joints satisfied the requirements for a 3-hour fire resistance rating.

Developed a technical solution that relates to the fire safety of buildings and structures. Particularly it can be used for the classification of unreinforced masonry structures of buildings on indicators their resistance to fire. This gives the possibility of reasonable use of the existing masonry structures with the actual fire-resistance rating in buildings of various categories according to their fire hazard.

This paper presents the progress in hydrogen safety research which includes some of studies carried out at HySAFER Centre of Ulster University during last two years 2016-2018. The results of four studies are presented: modeling and simulation of radiation from cryogenic underexpanded jet fires; improved fire test protocol for hydrogen storage composite vessels accounting for dependence of fire resistance rating on the burner heat release rate; validation of the pressure peaking phenomenon for unignited releases and jet fires; and modeling of hydrogen tank fuelling.
