本文详细介绍了不锈钢空心混凝土椭圆截面轴心受压性能的试验研究。采用30和100 MPa的普通和高强混凝土进行了试验研究。当前的研究基于短柱测试，因此仅限于横截面容量。基于作者提出的不锈钢圆钢管混凝土柱的计算公式，提出了一套新的椭圆空心不锈钢混凝土柱的计算公式。从有限的数据，目前可用的，该方程提供了一个准确和一致的预测复合填充不锈钢椭圆空心截面的轴向承载力。
This paper presents the details of an experimental investigation on the behaviour of axially loaded concrete-filled stainless steel elliptical hollow sections. The experimental investigation was conducted using normal and high strength concrete of 30 and 100 MPa. The current study is based on stub column tests and is therefore limited to cross-section capacity. Based on the equations proposed by the authors on concrete-filled stainless steel circular columns, a new set of equations for the stainless steel concrete-filled elliptical hollow sections were proposed. From the limited data currently available, the equation provides an accurate and consistent prediction of the axial capacity of the composite concrete-filled stainless steel elliptical hollow sections.
