Hollow Ratio and Stiffeners Effects Concrete Filled Double Steel Tubes Behaviour

Concrete Filled Double Steel Tubes are mostly used in bridge piers, tall buildings, offshore and coastal structures and power transmission towers. Finite element analyses via ABAQUS software have been performed aiming to evaluate the strength, ductility and plastic deformation of CFDST columns with...
