Survey of Building Structural Elements located at Underground for Improvement of Fire Resistant Performance
Kwon In-Kyu
요약
건축물의 지상층 주요구조부인 기둥, 보 및 바닥에 대한 내화성능의 연구는 활발하게 진행되고 있으나, 모든 구조적 하중을 지반으로 전달하는 지하층의 기둥을 비롯한 주요 구조부의 내화성능에 관한 자료 및 연구는 거의 없는 실정이다. 개구부율이 낮은 지하층에서의 화재크기는 지상층 화재보다 열에너지량이 크므로 구조적 붕괴의 위험성은 높다. 따라서 본 논문에서는 지하에 위치된 구조부재에 대한 내화성능의 적정성 평가를 위한 기본 자료 제공을 목적으로 국내외 지하 구조물의 내화법규정을 조사하고, 국내의 기시공된 건축물의 지하층의 구조형식, 구조재료 및 내화피복 현황을 분석하였다.
Abstract
Researches on fire resistant performance of primary structural elements such as columns and beams located at above the ground have actively been doing than those located at the below the ground from many researchers. But the structural elements such as columns at underground is very important in aspects of not only structural performance but also fire environment. The columns at the basement carry all the structural loads from the above and that means very critical in fire circumstances than that located at above the grounds. To evaluate the fire resistance performance of primary structural elements located at below the ground we conducted several sorts of surveys that contained fire regulations from several countries and structural types, materials and status of passive fire protection methods.
