Abstract: Two suitable reinforced concrete beams with CFRP plate at the compression zone for four-point bending beam static load testing, two respectively of a layer and two layers of beams strengthened by CFRP plates on edge compression zone.The load-deflection curve were measured;The failure pattern, effects of bending capacity, deflection and strain variation of the beams with CFRP plate at the compression zone;Finally, it is necessary to put forward its role in reinforcing concrete structures and deduced the bending capacity calculation formula of rectangular cross section which pasting CFRP plates for flexural members.

Key words: structural reinforcement;CFRP plate;reinforced concrete beam;bending capacity
