Abstract:
The anchorage zones have complicated structures and endured huge cable force in long-span cable-stayed bridge. In view of this characteristic, the model of anchoring box style cable anchorage structure was studied by large-scale finite element analysis sofeware.Under giant tension function,there were close relations between anchoring circle, setting plate and bearing plate,and the way of power transmission was an distinct structure condition non-linear behavior.So in the computation,authors used contact non-linear technology carrying on the simulation and compared it with usual simplification computational method.Through using this technology,authors found that the actual stress state and distribution were received and the instructive conclusions for optimizing the anchorage zones structural design were drawn.
