Embodiment 1
[0021] Embodiment one: see figure 1 , figure 2 , the method for improving the ductility of the FRP reinforced concrete frame structure is as follows: according to the cross-sectional size of the FRP reinforced concrete frame structure 1 and the quantity and diameter of the FRP tendon 2, the components 3 required in this embodiment are made, and the components 3 Drill the corresponding holes. When installing the FRP bar 2 in the FRP bar concrete frame structure, in figure 1 Install the fixed components 3 at the required component positions, and then pour concrete to complete the construction of the FRP-reinforced concrete frame structure. The specific operation steps are as follows:
[0022] (1) According to the component cross-sectional size of FRP reinforced concrete frame structure 1 and the quantity and diameter of FRP reinforced concrete frame structure 2, make components 3 (integral type);
[0023] (2) drilling a hole perpendicular to the surface in the component 3; ...
Embodiment 2
[0026] Embodiment two: see figure 2 , this embodiment is basically the same as the above-mentioned embodiment, the difference is that the components 3 are separated, that is, the components 3 can be installed on each or every few FRP ribs, and the components 3 can be installed in combination After that, the entire cross-sectional shape of the FRP reinforced concrete frame structural member 1 can still be assembled.
