Stationary Stochastic Response ofCFST Arch Bridge to Multi-component Seism ic Excitation

  • Publish Date: 25 Apr 2005
  • The response of concrete-filled steel tube (CFST) arch bridges tomulti-componentseismic excitation and its calculation were investigated using the theory of random vibration. A pseudo- excitation method for multi-component seismic excitation was proposed, the stationary stochastic response ofCFST arch bridges tomulti-component seismic excitation was analyzed with thismethod, and the effectof traverse brace stiffness on the stochastic responsewasdiscussed. The resultshows that thismethod has the same accuracy as the classic stochastic vibration method and an advantage in calculation velocity. Transverse and vertical seismic excitationshave a large effecton the internal force of arch rib, and the internal force increaseswith the increasing of traverse brace stiffness.
