A Study On Performance Design Using A Sprinkler System For Fire-Spread Prevention Of A Building Exterior, Seung Un Chae, Heung-You Kim, Uh-Sang Kwon, Bum-Yean Cho
International Institute for Infrastructure Resilience and Reconstruction (I3R2) Conference
A glass exterior material is normally used in buildings, but it also comes with a disadvantage—it is easily damaged by fire. If the glass exterior material is damaged, a fire can rapidly propagate inside the building space, leading to a lot of damage from the flame transfer to the other space. In this study, the performance of a sprinkler for flame propagation prevention was evaluated during an experiment with an actual proof fire. The study found that where the sprinkler is installed with the glass exterior material, the temperature does not exceed 60°C until the end of the test due …
Experimental Study On The Fire Resistance Performance Of Prestressed Composite Beam With Corrugated Web Under Standard Fire With Loading Condition, Heung-Youl Kim, Hyung-Jun Kim, Kyung-Hoon Park, Bum-Yean Cho
Experimental Study On The Fire Resistance Performance Of Prestressed Composite Beam With Corrugated Web Under Standard Fire With Loading Condition, Heung-Youl Kim, Hyung-Jun Kim, Kyung-Hoon Park, Bum-Yean Cho
International Institute for Infrastructure Resilience and Reconstruction (I3R2) Conference
In this study, fire resistance tests were performed on a conventional slim floor beam and a prestressed composite beam with corrugated webs, which is suitable for a long-span structure with a reduction in story height by utilizing the prestress and accordion effect. In the fire test program, the ISO 834 standard fire curve was adopted. Key test variables were the effect of prestress, shape of corrugated webs, and thickness of sprayed fireproofing material. All of the test specimens demonstrated enhanced fire resistance performance exceeding the expected performance level. The prestressed composite beams with corrugated webs especially showed excellent fire performance, …
The Study On Fire Safety By A Real-Scale Combustion Experiment Of Composite Material, Oh-Sang Kweon, Heung-Youl Kim, Seung-Un Chae, Bum-Yean Cho
The Study On Fire Safety By A Real-Scale Combustion Experiment Of Composite Material, Oh-Sang Kweon, Heung-Youl Kim, Seung-Un Chae, Bum-Yean Cho
International Institute for Infrastructure Resilience and Reconstruction (I3R2) Conference
In this study, a real-scale combustion experiment was carried out for a Styrofoam and glass wool sandwich panel to figure out the fire safety for the composite material used for a building. In the experiment, a heat release rate of a sandwich panel was measured by the ISO 9705 fire test method. Research has also tested and compared temperature change in the Large Scale Calorimeter (LSC) experiment equipment to evaluate the structural safety of the structure body. As a result of the experiment, the structural body with the Styrofoam sandwich panel collapsed which was caused by propagation, and in case …
Experimental Study On Fire Resistance Performance Of A Hollow Slab Using A Lightweight Hollow Sphere, Bum-Yean Cho, Hyung-Jun Kim, Kyung-Hoon Park, Heung-Youl Kim
Experimental Study On Fire Resistance Performance Of A Hollow Slab Using A Lightweight Hollow Sphere, Bum-Yean Cho, Hyung-Jun Kim, Kyung-Hoon Park, Heung-Youl Kim
International Institute for Infrastructure Resilience and Reconstruction (I3R2) Conference
This study evaluates the fire resistance performance (1–2h) of a reinforced concrete (RC) structure-void slab using a lightweight hollow sphere, which can reduce the unnecessary dynamic of removing the central concrete. For this experiment, we set up the depth of the concrete cover, live load, and span length as the factors. The result comes out with 50 mm cover depth of the RC structure hollow slab secured. It was shown that 120 minutes of fire resistance performance can be secured regardless of the length of the structure and loading. Among these factors, the resisting capability changes more sensitively with the …
