METHOD OF STRENGTHENING AN EXISTING INFRASTRUCTURE USING SPRAYED-FIBER REINFORCED POLYMER COMPOSITE

摘要

A construction technique for strengthening existing infrastructure and itscomponents (e.g.bridge columns) using sprayed fiber reinforced polymer (sprayed-FRP) made ofrandomlyoriented chopped fibers and resins on the said existing deficientinfrastructure. Sprayed-FRPcomposite laminates are applied to reinforced concrete (RC) or steel or woodenor masonrystructure substrates as an external reinforcement as effective means forobtaining higher levelof fiber utilization before premature failure.
