Abstract

PURPOSE:To permit to transmit all of the load bearing capacity of FRP member by a method wherein a splice plate, whose configuration is corresponding to the same of FRP member substantially, is bridged between the ends of FRP members and both of the members are calmped through bolts while interposing an adhesive agent between the FRP members and the splice plate. CONSTITUTION:The ends of FRP members are reinforced by employing either one of 0 deg./90 deg. cloth, bias cloth or unidirectional cloth to form a FRP reinforced layer 4 and a predetermined number of bolt holes are bored at predetermined positions so as to penetrate through the reinforcing layers. The splice plate 3 of FRP, similar to the sectional configuration of FRP member 1 to be con nected and having a configuration capable of enclosing the member 1, is rein forced in the same manner as the ends of the members 1. The plate 3 is divided into a plurality of members and are bored with the bolt holes corresponding to the same holes bored on the ends of the member 1. Subsequently, both rein forced ends of both members 1, 1 and connecting surfaces are coated with the adhesive agent 5 to bond them each other while bolts are penetrated through the bolt holes to clamp and integrate them.
