Abstract:Research purposes:Themain bridge ofXiangtan Liancheng Bridge is a flying-bird type concrete-filled steel tube cable-stayed arch combined bridge with spans arrangement of 120+400+120 m. The cable-stayed is anchored on the side beam, bridge tower and concrete-filled steel tube arch, which is unique and nove.l This paper analyzes the local stress in the anchorage zone of cable-beam and cable-towerwith three-dimensional finite element model for providing the reference to similarworks.
Research conclusions:Because the anchorage zones of cable-beam and cable-tower is affected by complex force, such as cable force, momen,t there are largermain-crush stress and pull stress existing in connected area ofanchorage zone and beam or tower. The anchorage zones should be reinforced by stee.l In addition, because there is largermain- pull stress existing in the areawhere the cable passes through the top face ofbeam and outside of tower, largermain- crush stress exists on the bottom of anchor steel plate.
