Ductility of Reinforced Concrete Beams
CVR Journal of Science & Technology, 2015 Concrete structures are designed by satisfying two criteria namely, safety and serviceability. Safety criterion checks whether the structure is safe in carrying the designed load or not. Serviceability criterion checks whether the developed deflections and crack widths are within the permissible limits or not.

Behaviour of GFRP rebars reinforced concrete elements under elevated temperature and fire
, 2003 PhDIn general, it is expected that concrete structures using Glass Fibre Reinforced Plastic (GFRP) rebars as reinforcement could have improved durability compared to normal steel reinforcement because of the corrosion resistance of the rebar. However,
