Concrete-filled double skin steel tubular (CFDST) columns subjected to long-term sustained loading
Abstract This paper carried out a series of tests on concrete-filled double skin steel tubes (CFDST) columns under long-term sustained loading condition. The test process included two stages, i.e. long-term service test and ultimate strength test. Numerical models on analysis of the CFDST column under long-term sustained loading were presented. A comparison of results calculated using these models showed generally good agreement with the test results. Additionally, a detailed analysis was performed to analyse the long-term behaviour of CFDST columns. Finally, simplified formula for calculating the ultimate strength of CFDST columns subjected to long-term sustained loading was proposed.
Highlights ► Experiments of CFDST column under long-term sustained loading. ► Analysis for the long-term loading behaviour of CFDST column. ► Formulas for strength calculation of CFDST column.
