摘　　要：通过对国产某型16Mn钢的恒温加载的试验研究,得到其强度折减系数随温度的升高而降低,600℃时f0.1、f0.5分别降为常温下强度的33%、50%左右;通过对该钢的恒载加温的试验研究得到其不同温度下的临界荷载水平,即在300℃、400℃、500℃、600℃时其临界荷载水平分别为0.70、0.55、0.50、0.30。为我国钢结构建筑耐火设计提供了重要的参考数据。Based on the experimental research of the loading after heated of one 16Mn steel produced in China,its strength fall coefficient will be reduced with the temperature rising.For example,f0.1 and f0.5 will drop to 33% and 50% of the normal temperature under 600 degree.Some critical load under different temperatures are obtained,which are 0.70,0.55,0.50 and 0.30 under 300,400,500 and 600 degree.This provides important basis data for fire resistance analysis of steel structure buildings.
