Abstract

Abstract As metropolitan areas become densely populated in Taiwan, with high-rise buildings located everywhere; elevators are becoming essential transport tools in buildings. Elevators usually connect each floor with vertical transportation, and play a significant role in personnel and goods loading. However, a large elevator shaft can become a path to extend fire if fire happens. Large amounts of flame and smoke are produced during a fire and the rising characteristics of smoke mean it can go through channels, stairs, and pipes. With the stack effect of high-rise buildings, the entire building can fill with smoke in a very short time, causing the fire can quickly spread to each floor and cause serious personnel casualties. This study investigates fire door structural strength changes in high temperature situations by using ANSYS, finite element analysis software, to verify the resistance of fireproof elevator door. This study also investigates the influences of various parameters to explores the effect of fire resistance time and provide numerical reference data to designers.
