摘要: Abstract Concrete-filled double-tube (CFDT) columns have the potential to be widely used in high-rise buildings due their very high load-carrying capacity, excellent ductility and good fire resistance. This new type of composite construction has attracted increasing research attention last decade, but there is a need develop practical design recommendations for this construction. paper aims study ultimate strength, strain corresponding strength (ductility), stiffness CFDT stub under axial compression. An existing finite element model directly square further modified simulate circular Numerical data are generated cover wide range parameters columns. Through regression analysis, simple equations proposed calculate compressive These can assist engineers conduct structural analysis
