碩士 === 元智大學 === 機械工程學系 === 99 === In this study, simulate the real fire scenarios of reinforced concrete(RC) beam that fire damage to caused by numerical simulation. The failure modes prediction to concrete spalling time and temperature, and that for concrete tensile strength make analysis of the effects. and beam of fire damage that prediction to spalling of concrete beams state. In general, spalling of concrete state is very complex, because it is affected by many factors is implicated; due to fire caused by concrete spalling the structure has been observed in experimental data and in real fire disaster of conditions under. Therefore, this study to first ,by FDS fire simulation software to simulate single interval ,and beam of by fire damage and the fire temperature, then by PHOENICS heat flow simulation software Analysis reinforced concrete composite rectangular beam of internal temperature distribution, and by different sizes of Heat release rate, Analysis to reinforced beam concrete by it given to permeability damage value of prediction to concrete spalling time and temperature and tensile strength of concrete make the effects of analysis. Expectation to provide reinforced concrete(RC) beam of by after fire damage; predict to spalling analysis method and structural safety of the numerical estimation method for reference and application.
