摘要
对钢管、钢管素混凝土、短钢纤维钢管混凝土、超短钢纤维钢管混凝土等 4组短柱在压力试验机上进行受压试验 ,分别测试出试件的纵向荷载与纵向变形的关系 .试验表明 ,在相同纵向受压荷载的作用下 ,超短钢纤维钢管混凝土短柱纵向受压变形最小 .
Compression tests have been performed on four groups of short columns ( steel_pipe, steel_pipe concrete, short_steel_fiber steel_pipe concrete, super_short_steel_fiber steel_pipe concrete) via a compression test machine in order to compare their mechanical characteristics of intensity and stability. Through testing, the relationship of the samples' longitudinal load and longitudinal distortion has been revealed. The result shows that under the same longitudinal load the super_short_steel_fiber steel_pipe concrete columns have the smallest longitudinal distortion among the four sample groups. The tests reveal that super_short_steel_fiber has notable function in increasing the stress resistance and stability of the concrete confined in steel columns.
