摘要
通过对20个圆形钢管混凝土短柱试件在恒高温作用后的轴压试验,研究了圆形钢管混凝土短柱的轴压力学性能。在分析试验数据的基础上,探讨了试验中对恒温温度(℃)和恒温时间(小时)的选择对研究结果的影响。
The behavior of circular stub columns of concrete filled steel tubes with circular cross-section after the action of constant high temperature and under axial load was investigated experimentally. A total of 20 specimens were studied. Based on analyzing the obtained data,the influences of selecting constant temperature (℃)and acting time(hour)on the research results,are discussed.
