| Abstract: | According to the characteristics of concrete-filled tubular frame arch bridges with flexible bars, a conception of dynamic finite element method and general strategy of construction control, which is based on dynamic imitation analysis, was proposed. In the strategy, accurate tension of cable forces of flexible bars and control of top displacement of piers are two main construction control objections. In addition, a method for dealing with the temperature influence and a skill of assignment of the factor for calculating shrink and creep of structures was given out. It is shown by the experimental results that the proposed method and technique is valid. |
