| Abstract |
Stainless steel, which has corrosion resistance, fire resistance efficiency and elongation is superior to carbon steel.
This study presents centrally loaded experiments on cold-formed stainless steel pipe 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 of stainless steel and the experiments of stainless steel pipe columns. The paper presents compressed experiments on stainless steel pipe columns, including stub column tests and coupon tests. On the column experiments, a total 12 stainless steel pipe column experiments are conducted, the slenderness ratios(λ=20, 30, 40, 50, 60, 70) as parameter. The experimental results were compared with the design standard curves, AIK-LSD and AIJ-LSD, AISC-LRFD, SIJ-ASD curves.
Test result showed that stainless steel pipe columns could be predicted superior to strength and plastic deformation. And that can be applied to structural member with many benefits. But it requires reasonable code for the stainless steel as more experiments and study in the future, according to it leaves much room for improvement, a low yield strength(Fy=2.1tf/㎠) of Korean Standards, a high cost, the not established design code, etc. |
