Study on External Prestressed Concrete-Filled Steel Tubular Flexural Member
According to good property of concrete-filled steel tubes(CFST) when they are subjected to compression load and their disadvantage to bending load. A new type of composite external prestressed concrete-filled steel tubular structure has been presented in this paper, which has the high tension strength of prestressed tendon and good anti-compression capacity of CFST. Based on the analysis of the mechanism, the flexural capacity of the structure can be greatly enhanced. And the criterion and method is given.
