초록

본 연구는 Eurogode 3 Part 1.3을 근거하여 온도증가에 따른 압축을 받는 냉간성형 C-형강 기둥의 플랜지와 웨브의 탄성국부좌굴 응력 해석 프로그램을 개발하였다. 고온에서 응력-변형률 관계식은 Eurocode 3 Part 1.2를 근거하였다. 온도증가에 따른 압축을 받는 냉간성형 C-형강의 임계온도와 탄성국부좌굴 응력은 본 연구에서 개발한 컴퓨터 프로그램에 의해 해석하였고, 해석 예에 대한 비교 고찰을 하였다.

This paper discusses the development of a computer program to analyze elastic local buckling stress based on Eurocode 3 Part 1.3 for the flange and web of cold-formed channel columns under compression at elevated temperatures. The high-temperature, stress-strain relationships of the steel used in this paper were determined according to Eurocode 3 Part 1.2. The critical temperatures and the elastic local buckling stresses of cold-formed channel columns under compression at elevated temperatures were analyzed with the computer program developed in this study. Analysis examples were given to show the applicability of the computer program.
