dc.titleA study of vertical fire spread in multi-storey buildings - windowsill wallen_US
dcterms.abstractOne of the most common forms of fire spreading vertically on the building's facade is the indoor fire burning the combustible material on the upper floor through openings on the building's exterior walls. One of the effective measures to prevent the vertical spread of fire is to increase the height of the window-sill wall, the second is to set fire prevention eaves above the window ledge without burning. This study will mainly discuss the fire resistance performance of windowsill wall. Windows are an important way for indoor fires to spread outwards. In order to determine the window-sill wall and the effect of preventing the vertical spread of fire, the fire dynamics simulation software FDS was used to select the setting of office and hotel room fire scenes, and the numerical simulation study was carried out. The height of windowsill wall are 0.2m, 0.4m, 0.6m, 0.8m, 1.0m, 1.2m, 1.4m respectively. The thickness of the floor in the 6 fire separation modes is 200 mm. A 6-storey office and hotel building is selected as the simulation object. Each floor is 3.8 meters high, and the area of each room is 6m times 6m. The burning room is the second floor. Each room has one window and the height varies with the width of the sill wall. The results show that increasing the height of the window-sill wall within a certain range will be beneficial to preventing the vertical spread of fire, but exceeding the range may cause adverse effects.en_US
