Experimental behavior of reinforced concrete beams strengthened with prestressed CFRP shear straps
(American Society of Civil EngineersJournal of Composites for Construction (ASCE), 2007)
One promising means of increasing the capacity of existing shear-deficient beams is to strengthen the structure using external prestressed carbon fiber reinforced polymer (CFRP) straps. In this system, layers of CFRP tape ...
Nonlinear FE analysis of cracks in tension and shear
(Institute of Civil EngineersMagazine of Concrete Research, 2007-05-01)
Smeared-crack finite element (FE) analyses of reinforced-concrete beams strengthened with prestressed carbonfibre-reinforced polymer (CFRP) shear straps have shown that, at high load levels, the stresses in the straps ...
