摘要：
A technique of strengthening the bare stone beams with prefabricated CFRP-reinforced stone plates is proposed and investigated in this research. A thin stone plate embedded with CFRP bars is prefabricated first and then pasted to the tensile surface of stone beams. The prefabricated plate is made of stone which is the same material with that in the strengthened stone beam, so as to maintain the appearance of the traditional structural member. The strengthening effect of this technique is experimentally evaluated herein. Three stone-beam specimens strengthened with such prefabricated plates and one bare stone-beam specimen were tested under four-point bending. The main test parameter considered was the amount of CFRP bars. Test results showed that, the prefabricated plate could shift the failure pattern of a bare stone beam from brittle fracture to a more ductile manner, and significantly increased the load-carrying capacity and deformation capacity of the stone beam. During the loading procedure, good bond behavior was achieved between the prefabricated stone plate and the stone beam, and no end-slip in the CFRP bars was observed, ensuring effective composite actions between the different components. The flexural strength of the strengthened stone beams tends to increase along with the increase of the CFRP reinforcement ratio. This paper could provide reference for the fast strengthening of stone flexural members.
