摘要
通过对2根H形截面钢柱进行火灾行为的试验研究,得出了钢柱在火灾下的侧向变形和轴向变形情况,为钢结构火灾行为研究提供依据。
The behaviors of two H-sectlon steel columns under fire are investigated. All the columns are full scale with 3300 mm length. Axially loaded steel columns are supported with one end pinned and the other end fixed. The knife-edge is adopted to simulate one pinned end,which is permitted to move around strong axes. The changes of lateral deflection and axial deflection with temperature increasing are presented. Conclusion of this paper provides a basis for further research to explore fire behaviors of steel structures.
