Flexural behavior of RC continuous T-beams reinforced with hybrid CFRP/ steel bars (experimental and numerical study)

This study presents experimental and numerical investigations to understand the response failure of hybrid RC continuous T-beams reinforced in flexure by both Carbon Fiber Reinforced Polymer (CFRP) bars steel at sagging hogging regions. Three were constructed experimentally studied discuss three parameters which are type reinforcement material, relation between reinforcement, moment redistribution. The control beam was with rebars that have been designed fail flexure. second CFRP/ region third one while CFRP bars. All critical sections tested specimens same axial stiffness for Experimental results revealed redistribution ratio mode depend on using regions helped serviceability limits beams.This also suggests validates a 3D model simulate performance finite element (FE) software “ANSYS”. agreed observations indicated significant effect material beams.
