| Abstract: | Square expansive concrete-filled steel tubes (ECFT) are a sort of optimization design for concrete-filled steel tubes (CFT). On the basis of test in eccentrically compressed square ECFT,the mechanics behavior of the member under eccentrically compressive load is studied in accordance with existing codes and specifications. The formula for the ultimate strength of eccentrically compressed square ECFT short columns is proposed by using the limit analysis theory, which can be a reference for the design and the theory study of square ECFT members. |
