ANCHORAGE METHOD OF CCFP (CONSOLIDATED CARBON FIBER PLATE) FOR STRENGTHENING OF RC SLABS SUBJECTED TO NEGATIVE BENDING MOMENT

Abstract

Consolidated Carbon Fiber Plate (CCFP) has significant tensile strength and higher applicability, so it is often employed for strengthening of RC member. The present study focused on anchorage methods of CCFP for cantilever RC slabs subjected to negative bending moment. As the fundamental experiment, bending tests were conducted by using beam specimen with various anchorage methods. Based on the fundamental experiment, we have devised the simplified method that embed CCFP in the surface of RC member. In order to investigate applicability of the anchorage method, the wheel running fatigue test was conducted by using a cantilever RC slab strengthened by CCFP.
