Strengthening of RCC beam using FRP laminates

Abstract

As we know Concrete is strong in compression and weak in tension because of structural cracking at a relatively low level of stress, it means concrete doesn’t behave same in tension and compression but Steel reinforcement bars behave similarly in tension and compression. The stress–strain response of concrete in compression is nearly linear at the beginning of loading up to approximately 0.7 fc . Beyond that stress, the response becomes highly nonlinear up to failure. The ultimate strength of concrete in tension is relatively low.
