Abstract：Research purposes：The V-shaped rigid-frame and arch structure combined bridge is formed by connection of slant legs of main span of V-shaped pier continuous rigid-frame with the arch abutment of concrete-filled steel tube arch. It has the feature that the arch and V-shaped pier continuous rigid-frame bear the load together and its performance of the structure is different from general beam-arch combined bridge. The research is done to reveal the combination effect of beam-arch of the combined bridge.
Research conclusions：Because of the enforcement effect of arch rib on V-shaped pier continuous rigid-frame, the maximum bending moment and deflection of the middle span of rigid-frame and arch structure combined bridge under effect of the active load decrease by 50%, the deflection of the middle span caused by the concrete creeping and shrinkage in the later stage is 12% of V-shaped pier rigid-frame bridge and the vertical stiffness of V-shaped rigid-frame and arch structure combined bridge is 2.56 trimes of V-shaped rigid-frame bridge, so the combination effect of the beam-arch of V-shaped rigid-frame and arch structure combined bridge is very obvious.
