강구조물 내화성능 해석 프로그램 개발에 관한 연구

초록

There are two ways of evaluation for fire resistance performance on steel structures. One is prescriptive method and the other is performance based fire engineering design. To practice the fire engineering design in steel structures with easy, the analytic program is very effective and useful in terms of cost for fire test, evaluation period and etc. To make a new analytic program of evaluation for fire resistance, the backbone of building laws and the technical references related to fire engineering design method were surveyed and the mechanical and thermal data were gathered from the previous experimental data. The analytic program was developed by using the excel utilities and designed 3 major parts; input, solving and output. To verify the developed analytic program the comparison was done by using the previous fire test with standard sized-scale column built with a SS 400. The comparison showed that the increasing of temperature and deformation with time were very similar between analytic results and fire test. But the rapid increase of deformation according to expansion and local buckling caused from higher temperature couldn't be calculated. To increase more the reliability of analytic program the calculation of deformation caused by the expansion and the local buckling should be needed.
