Shearing experiment device for FRP rib material in tension state

The invention relates to a shearing experiment device for an FRP rib material in a tension state. The device comprises a test piece, the two ends of the test piece are anchored in an anchorage devicewith threads at the end parts through epoxy resin, and the anchorage device is installed in a test device in a matched mode. The test device comprises a fixed supporting component and a middle shearing component. The fixed supporting component comprises two symmetrically-arranged steel plates and four long supporting screws between the two steel plates, a hole is formed in the center of each steelplate, a short screw passes through each hole, and the short screws are connected with the test piece through a sleeve with internal threads turned at the two ends. The shearing component is arrangedin the middle of the test piece and comprises two concave clamps and two convex clamping pieces, and the clamps and the clamping pieces are provided with ducts for the test piece to penetrate throughand are tightly attached th
