Compared with the prior art, the utility model provides the high-ductility FRP rib concrete shear member, which has the following beneficial effects:

1. this high ductility FRP muscle concrete shear member, through the square cage of FRP that is equipped with, the square cage of FRP is by X axle direction muscle, Y axle direction muscle and Z axle direction muscle, and X axle direction muscle and Y axle direction muscle all adopt the arc muscle that outwards protrusion set up, can effectually bear the outside shear stress to the high ductility concrete body, increase the self structural strength of high ductility concrete body.

2. This high ductility FRP muscle concrete shear member through setting up the FRP that is inside at the square cage of FRP bears the muscle, and the FRP bears the muscle and is the cross shape, can firmly support the square cage of FRP, increases the ability of the square cage of FRP to bear stress.

3. According to the high-ductility FRP rib concrete shear member, the top rib is arranged, so that the shearing stress stressed on the outer part of the high-ductility concrete body can be directly transmitted to the FRP square cage and the FRP bearing rib, and the straightness of shearing force is improved.

The device has the advantages that the non-related parts are the same as or can be realized by adopting the prior art, the FRP square cage and the FRP bearing ribs are adopted as the internal bearing structure, the shearing stress of the external part on the high-ductility concrete body can be effectively borne, and the self structural strength of the high-ductility concrete body is increased.
