Abstract
Purpose: In order to secure a specific fire diffusion model, this study compares and analyzes the NIST UL standard application scenario and the performance-oriented design application scenario and examines the difference between the fire diffusion model and the surface fire model. Method: Temperature, visibility, and CO sensors were installed for each scenario using FDS, and the two scenarios were compared and analyzed through the changes. Result: As a result of analyzing the temperature, visibility, and CO for each scenario, the NIST UL standard application scenario is very similar to the actual fire, and the performance-oriented design application scenario shows a harsh fire situation. Conclusion: When designing fire safety for large buildings such as distribution warehouses, it is important to prepare comprehensive fire safety measures in consideration of both actual fire and harsh fire conditions.
연구목적: 본 연구는 구체적인 화재 확산 모델을 확보하기 위해 NIST UL 기준 적용 시나리오와 성능위주설계 적용 시나리오를 비교 분석하고 화재 확산 모델과 표면 화재 모델의 차이점을 보고자 한다. 연구방법: FDS를 활용하여 시나리오 별로 온도·가시도·CO 센서를 설치하고 그 변화를 통해 두 시나리오를 비교 분석하였다. 연구결과: 시나리오 별로 온도·가시도·CO를 분석한 결과 NIST UL 기준 적용 시나리오는 실화재와 매우 유사하고, 성능위주설계 적용 시나리오는 가혹한 화재 상황을 보여준다. 결론: 물류창고와 같은 대형 건축물의 화재 안전 설계 시에는 실화재 및 가혹한 화재 상황을 모두 고려하여 종합적인 화재 안전 대책을 마련하는 것이 중요하다.
