초록

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.
