| Abstract |
The study was intended to conduct the heat transfer analysis of the structural elements that serves the basis of performance-based fire resistance evaluation which has been widely implemented by the fire-related institutes (BRE, SP, NIST etc) in advanced nations, thereby carrying out the element temperature evaluation and the effect of heat characteristics under the standard fire condition (ISO). Based on this, an analytic study aimed to develop the performance-based fire-responding temperature control and improve the shape of the elements under the nonlinear stress condition in fire was carried out. The study to identify the optimal shape condition was conducted in an effort to develop the reliable fire resistance performance of the modular beam. This heat transfer analysis was conducted prior to carrying out the costly fire test so as to provide the numerical analysis technology enable to repeat the process, and based on data from the preceding test for material properties depending on temperature of component material, analysis modeling was implemented. ABACUS 6.7.1, an analysis program using finite element analysis method was employed as interpretation software to predict the fire resistance performance through the maximum temperature analysis of the modular beam, which enables to determine the optimal interval of modular beam and the thickness of fire-resistant gypsum board. And the verification experiment was followed based on the result of the analysis outcome. It was determined to use 30mm thick fire?resistant gypsum board for optimal fire resistance, and it was found to be able to grant the 180-minute fire resistance under the standard fire condition when the interval was set as 30mm. |
