Title

INVESTIGATION INTO BEHAVIOR OF CONCRETE FILLED DOUBLE SKIN STEEL TUBULAR (CFDST) COLUMNS

Pages

  635-647

Abstract

 Concrete filled double skin STEEL tubular (CFDST) members can be recognized as a new kind of CFT construction. They consist of two concentric STEEL tubes with concrete sandwiched between them, the STEEL tubes can be circular hollow sections (CHS) or square hollow sections (SHS) where both inner and outer tubes are circular hollow sections. CFDSTs were firstly introduced for vessels to resist external pressure. Strong potential of using CFDST in offshore construction, highways and high-rise bridge piers. All of analysis have been undertaken using ANSYS which is a general purpose finite element programe designed especially for advanced structural analysis. In order to verify the finite element model, a comparison between the experimental results and finite element results was carried out. Generally, good agreement between the experimental and numerical curves is achieved. The effective parameters are the bond between the STEEL and internal concrete, local buckling, strength of STEEL tube and concrete, loading conditions of columns.The result of this study clearly exhibit the high strength and DUCTILITY of the CFDST columns under axial loading, and they have lighter weight, than their CFT counterparts.
