The member 1 is a columnar elongated body with an H-shaped cross section, and its joint end is made of reinforcing fiber cloth made of glass fiber, carbon fiber, etc., and a curable resin such as unsaturated polyester resin or epoxy resin. Then, the FRP reinforcing layer 4 is formed by laminating them using a hand lay-up method or the like. Figure 1 shows the FRP reinforcement layer 4 using bias cloth as the reinforcing fiber cloth, and Figure 2 shows the FRP reinforcement layer 4 using unidirectional cloth as the reinforcing fiber cloth.
The FRP reinforcing layer 4 is shown, and FIG. 3 shows the FRP reinforcing layer 4 using 0°/90° cloth as the reinforcing fiber cloth.

This splice plate 3 is made of FRP and is reinforced in the same manner as the ends of the FRP member 1. Also, this splice plate 3
is divided into a plurality of members for manufacturing and usage reasons, and when the FRP member 1 is H-shaped, it is composed of six members 3a, 3b, 3c, 3d, 3e, and 3f. Furthermore, splice plate 3 has

Since the ends of the FRP members 1, 1 and the splice plate 3 are reinforced, the bearing capacity of the bolts between the FRP members 1, 1 and the splice plate 3 is improved, and the splice plate 3 supports the FRP members 1, 1. Since it is provided so as to wrap around the adhesive 5, the bonding area of the adhesive 5 increases and the bonding strength increases.
The full strength of the FRP members 1, 1 is now transmitted.
