Experimental research of seismic behavior and surplus bearing capacity of CFDST under reversed loading
Abstract
The concrete-filled double skin steel tubes (CFDST) column is a new type of steel composite structure column. At present, international and domestic research are still lacking in regards to this composite structure column. Therefore, a study of the composite structure column would have great theoretical and practical significance. In this paper, an experiment using concrete-filled double skin steel tubes columns with square-circular section is conducted under repeated loading and then under static axial compression. The test results show that the new type of composite structure column has excellent ductility and relatively good surplus bearing capacity. So, the test has laid a certain foundation for doing analysis and study on the new type of composite structure column in the future.
