Influence of Suspender Tension Sequence on Structural Stress of Concrete-filled Steel Tubular Arch Bridge
The tension of boom cable is an important link in the construction of concrete-filled steel tubular arch bridge.The internal force distribution and deformation of the structure will be affected by the different tension order of boom cable.In order to study the in-fluence of the tension sequence of boom cable on the structural stress of concrete-filled steel tubular arch bridge,a 3D simulation model of the new built Qinfangcheng Bridge is built by the finite element software,analyzed the law of change of displacement and in-ternal force of the structure under three kinds of boom cable tension sequence.The results show that stretch symmetrically from the middle of the span to the both ends is the best scheme for the construction of the boom cable.
