Abstract：High-strength flexible cable ring is used in vertical splices of assembled concrete shear wall,and ultra-high perfor-mance concrete(UHPC)is used to prepare high-strength flexible cable ring-UHPC nodes of assembled shear wall instead of normal concrete(NSC),and the effects of splicing material strength/type,high-strength flexible cable ring diameter and number of arrange-ments on shear-resisting performance of high-strength flexible cable ring-UHPC nodes are investigated.The results show that the high-strength flexible cable ring-UHPC nodes of assembled shear walls have high bearing capacity and plastic deformation capaci-ty,and the UHPC can change the damage morphology of the nodes from brittle damage to ductile damage.Compared with increas-ing the diameter and number of high-strength flexible cable ring,the improvement of node shear bearing capacity by adopting UH-PC in the backing zone is more obvious.The calculation method of shear bearing capacity of the node is proposed,and its theoret-ical value is slightly smaller than the simulated value,which has a good safety margin.
