Abstract

Abstract

In order to study the mechanical properties of thin-walled stainless steel tube composite short columns filled with steel-reinforced concrete, six concrete filled thin-walled stainless steel tube composite short columns were designed, including four stainless steel tube composite columns filled with steel-reinforced concrete and two concrete filled stainless steel tube stub columns for comparison. The failure modes, load-displacement curves, bearing capacity and strain characteristics of each specimen were analyzed by the results of axial compression performance test of stainless steel pipe composite short columns. The effects of different variables on the ultimate bearing capacity and residual bearing capacity were studied. The test results showed that stainless steel tube composite short columns filled with steel-reinforced concrete had higher bearing capacity and better ductility. The steel ratio had a great influence on the ultimate bearing capacity. The ultimate bearing capacity of specimens was improved significantly with the increase of steel ratio and concrete strength. The test results of bearing capacity were compared with the predicted bearing capacity using the Eurocode 4, GB 50936 and the proposed formula by related scholars. The formula considering the dual confinement effect of steel tube and section steel could predict accurately the bearing capacity of stainless steel tube composite short column filled with steel-reinforced concrete.
