Abstract |
This study presents centrally loaded experiments on cold-formed stainless steel and carbon steel circular hollow section columns. And attempts to experiment for the use of these stainless steel columns as structural compression members. An important part of the study is to investigate experimentally the mechanical properties and the strength of columns, which compared the stainless steel circular hollow section with the carbon steel circular hollow section. The paper presents compressed experiments on columns, including stub column tests and coupon tests. On the column experiments, a total 24 stainless steel and carbon steel column experiments are conducted, the slenderness ratios(λ=20, 30, 40, 50, 60, 70) as parameter. The experimental results were compared with the multiple column curves, ECCS and SSRC. Test result showed that stainless steel circular hollow section columns could be predicted superior to strength and plastic deformation. And that can be applied to structural members with many benefits. |
