표준화재조건 모듈러보 내화성능 예측기법에 관한 연구 = A Study on Prediction Techniques about Fire Resistance of Modular Beam in ISO Fire

다국어 초록 (Multilingual Abstract)

The modular beam made of steel material is wholly responsible for the load stress of the structure, therefore securing the fire-resistant capacity of the steel beam is absolutely important. The economic efficiency achieved by minimizing the thickness of the fire-resistant board attached, is also essential at the same time. Accordingly, a study of optimization of the thickness and interval of fire-resistant boards shall be conducted side by side. Therefore, in this study we have anticipated fire-resistant capacity by using a general-purpose S/W for finite elements, ABAQUS(6.7.1), in order to propose the configurable conditions that can secure the optimal fire-resisting capacity of modular beam. As a result of this analysis, it was impossible to secure the fire-resistance capacity when directly attaching fire-resistant board(30mm) on the modular board in accordance with KS F 2257-1, and the fire-resistant boards were manufactured in shape of module in consideration of its installation interval rather than direct application.
