| Abstract: | The steel tube of Concrete Filled Steel Tubular(CFST) structure will produce initial stress while in the processing of(construction.)The initial stress problems of CFST architecture columns were reviewed,and based on the researching result of the existing members,the initial stress's degree about several existing kinds of different span and section-shape CFST arch bridges has been analyzed and the initial stress problems of CFST arch bridge were preliminary discussed.In the end,some problems that need to be solved about CFST arch bridge were indicated and its research and advice also presented. |
