ABSTRACT
ABSTRACT: Steel anchor beam is a main kind of cable-pylon anchorage for cable-stayed bridge, and three different construction schemes are considered for it: Scheme 1, keep steel anchor beams simple supported on the brackets; Scheme 2, keep steel anchor beams simple supported on the brackets until initial tension is finished; Scheme 3, keep steel anchor beams fixed with brackets all the time. In this paper, the spatial finite element model of New Yalu River Bridge, a cable-stayed bridge, was established. Different construction schemes of steel anchor beams were proposed and the stress, as well as force distribution of anchorage zone under different construction schemes had been analyzed.
