Description
Reinforced concrete beam members are load-carrying members in structures. The beams performance is largely depending on the condition of the tensile reinforcement in members and quantity in the beam. Focus is put on flexural strengthening, which currently is the most common application field for composite materials in structural engineering. Generally, pre-stressed FRP will be demonstrated to follow the principle of conventional pre-stressed concrete by resulting in higher cracking, yielding, and bearing loads. Especially under service loads, the structural behavior is improved. Civil structures in several situations require strengthening of the structural members due to lack of stiffness, strength, serviceability, durability. Some situations where the members are in need of rehabilitation in their lifespan. There are many situations where the requirement of strengthening is must for structures such as Retrofit for seismic effected building.
