Long Term Load-Carrying Capacity of Eccentrically Compressed Concrete Filled Steel Tubular Members
Based on the creep model of CFST members constructed with the Elastic Continuation and Plastic Flow theory of concrete creep and the creep theory of concrete under multi-axial stresses, the paper studies the load-carrying capacity of eccentrically compressed CFST members with consideration of creep. Some eccentrically compressed CFST members’ long-term loadbearing capacity is calculated and corresponding results are compared with the load-carrying capacity without consideration of creep. According to the analysis of calculating results, it can be concluded that creep will decrease the load carrying capacity of eccentrically compressed CFST members, and it should be paid enough attentions in actual engineering.
