Abstract
![CDATA[The aim of this paper is to study the behaviour of stiffened concrete-filled double tube (CFDT) columns through numerical analysis. In this study, the inner and outer steel tubes are circular. Two types of stiffeners are studied (T, bar and rectangular stiffeners). The stiffeners are welded with inner and outer steel tubes. Finite element (FE) model that was verified with previous test results is used to study the behaviour of CFDT columns with the proposed stiffening method. FE model was used to study the effect of different parameters on the behaviour of stiffened CFDT columns. From the obtained result it can be noticed that using stiffeners with CFDT columns can increase its axial load capacity by about 15%. A simplified equation is developed to predict the axial design strength of stiffened CFDT columns.]]
