Experimental Investigation on Behavior of Rectangular Concrete-Filled Stainless Steel Tubular Stub Columns under Axial Loading

摘要

摘要:
为了研究矩形不锈钢管混凝土短柱轴压承载力性能，对7组不同截面尺寸的矩形不锈钢管混凝土短柱进行轴压试验，得到了不同试件的破坏模式、荷载-位移曲线、荷载-横向应变曲线、荷载-纵向应变曲线、荷载-长宽比曲线，分析了矩形截面长宽比对试件承载力的影响. 研究结果表明：矩形不锈钢管混凝土短柱在轴向压力作用下，其典型破坏模式为试件局部向外屈曲破坏；在相同长宽比的情况下，壁厚由4 mm增加到6 mm时，试件承载力增加25%~57%；在相同壁厚的情况下，长宽比由1增加到2，试件承载力减小22%~30%；将本文试验数据与国内外普通碳钢钢管混凝土柱的相关规范和标准的计算结果进行对比分析，发现不锈钢管混凝土短柱轴压承载力较相同截面的普通碳钢钢管混凝土短柱承载力平均高出14%；通过数值拟合得到了轴压承载力计算公式，该计算公式能较好地预测矩形不锈钢管混凝土短柱轴压承载力.

Abstract:
In order to study the axial compressive behavior of rectangular concrete-filled stainless steel tubular (CFSST) short columns, axial compression tests were conducted on seven groups of rectangular CFSST short columns with different cross-sectional sizes. The failure modes, load-displacement curves, load-circumferential strain curves, load-longitudinal strain curves, and load-cross-sectional aspect ratio curves of different specimens under axial compression were obtained. The influence of aspect ratio of the rectangular cross-section on the bearing capacity of the specimens was analyzed. The results show that the typical failure mode of rectangular CFSST short columns under axial compression was local outward buckling. Under the same aspect ratio, when the wall thickness of the specimens increases from 4 mm to 6 mm, the bearing capacity of the specimens increases by 25%–57%. With the fixed wall thickness, when the aspect ratio of specimens increases from 1 to 2, the bearing capacity decreases by 22%–30%. Comparison of the test results with the calculated results by relevant codes and standards indicates that the bearing capacity of CFSST stub columns is more than 14% higher than that of the concrete-filled conventional carbon steel tubular stub columns with the same section. Furthermore, a formula for calculating the axial compression bearing capacity is obtained by numerical fitting of the data obtained in this study and those from literature, which can well predict the bearing capacity of rectangular CFSST short columns.
