Abstract EN
:The structural rehabilitation of reinforced lightweight aggregate concrete beams in shear was studied with resin injection.
A series of model beams, reinforced in shear, were loaded in the laboratory until failure, repair and again loaded to failure .The variables in the test program were shear span-to-depth ratio 4.0,3.0,2.5,2.0,1.5 and 1.0 ; and shear reinforcement index ,ρvfy= 0.493,0.704 and 0.896 MPa .Experimental failure loads are compared with predictions using ACI 318M-02 code and the modified compression field theory by the program of “Response 2000” .After testing ,the beams failed due to new diagonal cracks .The ratio of ultimate load to crack load varies from 1.5 for a/d >2 to 2.27 for a/d ≤ 2 (deep beams) .Test results indicate the ACI 318M-02 is conservative .
