- Abstract:
- According to the deficiency of numerical simulation analysis on segment selection in existing suspender anchorage zone and the characteristie of suspender anchorage zone structure in existing cable-stayedand self-anchored suspension combination bridge, 8 shell element models analysis of two anchorage zone struc-tures about four diffident anchor segment length were established. Stress distribution, displacement and buck.ling behavior of anchorage zone on the 8 models were compared. The comparison shows that, when the sameanchorage structure form is adopted, the influences of anchor segment length on the stress distribution of an.chorage zone are large ; the variation of overall dellection in the anchorage zone tends to be stable with the segment length increase; the segment length section have significant elfect on buckling behavior of anchor strucNo matter what kind of anchor construction set is adopted, the selection length of anchor segment is attire.least 2 times height of girder away from anchorage zone in order to reflect mechanical characteristics of anchorstructure. The results can be used as a reference for numerical simulation and model tests of anchor structure.
