Experimental Research on the Stiffness of CFRP Reinforced Concrete Beam
Keyword(s):
This thesis analyses the destruction mode, the crack developing and beam deflection changes of 20 reinforced concrete beams including un-strengthened beam, direct strengthened beam and secondary load reinforced beam through tests and researches. The results show that using CFRP to strengthen the reinforced concrete beams will not only effectively increase the bearing capacity of the beam, but also inhibit the beam cracking and improve the flexural rigidity of the beam during normal use. In addition, the initial damage will have a certain impact on the stiffness of the strengthened beam.
