Behavior Of Hybrid Frp-Concrete-Steel Double-Skin Tubular Columns With A Square Outer Tube And A Circular Innert Tube Subjected To Axial Compression, Tao Yu, J G. Teng

Faculty of Engineering and Information Sciences - Papers: Part A

Hybrid fiber-reinforced polymer (FRP) concrete steel, double skin tubular columns (DSTCs) are a new form of hybrid columns. The most common sectional form of hybrid DSTCs consists of a layer of concrete sandwiched between a circular inner steel tube and a circular outer FRP tube whose fiber directions are close to the hoop detection to provide effective confinement to the concrete. Much recent research has been conducted on circular hybrid DSTCs, which has demonstrated that the combination of the three constituent materials leads to several advantages not available with existing forms of columns. In practical applications, for aesthetic and other …
