摘要
Abstract
The bearing capacity of solid and hollow recycled concrete filled steel tubular (R-CFST) columns have been studied through experiments and theories. The research indicates that the ultimate bearing capacity formula under biaxial compression of solid concrete filled steel tubular (S-CFST) short columns can be used for solid recycled concrete filled steel tubular (SR-CFST) short columns. The ultimate bearing capacity formula under biaxial compression of hollow recycled concrete filled steel tubular (HR-CFST) long columns is related to the elastic modulus of recycled concrete. The fire tests indicate that fire-resistanee performance of R-CFST long coLumns is better than that of ordinary CFST long columns and the computational formula of fire resistance period of R-CFST long columns has been given.关键词
