The Study on Carbon Fiber Reinforced Concrete Beams based on Finite Element Analysis

摘要

Carbon fiber-reinforced polymer (CFRP) sheets have recently become popular for use as repair or rehabilitation material for deteriorated carbon fiber reinforced concrete structures.Carbon fiber reinforced concrete beams were analyzed by finite element software ANASYS.Through the finite element analysis,the results showed that using bonded CFRP to strengthen R.C.beams can significantly increase their load carrying capacity.However,the beams with prestressed CFRP can withstand larger ultimate loads than beams with bonded CFRP.Using bonded CFRP to strengthen R.C.beams can obviously reduce the ultimate deflection.
