Experimental Research in Flexural Behavior of Carbon Fiber Polymer Strengthened Beams

This experimental research has studied the flexural behavior of CFRP strengthened beams. Four simply supported beams, reinforced using CFRP laminates where subjected to different sustaining loads and tested in flexure. The main of the test is to examine the effects of initial load and load history on the ultimate strength of reinforced concrete beams by externally bonded CFRP materials. The theoretical moment-curvature relationship and the load-displacement response of the tested beams were predicted by using software CATIAV6. Comparison has been made between numerical and experimental results. The test results showed that the strengthened patterns had influence on the beams structural performance, improving load capacity, increased flexural strength, enhanced flexural stiffness, modifying structural behavior and changing failure mode.
