Analysis and Design of Multistorey RC Frame Using FRP Reinforcement

ABSTRACT The use of fibre reinforced polymers (FRP) as construction materials is gaining acceptance in the construction industry. The primary reason for this increase is the superior performance of FRP reinforcement in corrosive environments, its long term durability, high tensile strength-to-weight ratio, electromagnetic neutrality and resistance to chemical attacks. The use of FRP bars as concrete reinforcement is relatively new, with very few applications in practice, although externally applied FRP sheets, strips and bars for rehabilitation and seismic retrofit purposes is not uncommon. There is lack of research in performance and design of new FRP reinforced concrete structures; particularly for seismically active regions. The use of FRP bars as reinforcement is a new concept with limited experimental and analytical information. The main purpose of this research is to study seismic behavior of multi-storey, multibay structure by using GFRP reinforcement using nonlinear pushover analysis. Pushover analysis was carried out using ETABS 9.7.4 software and using M3 and V2 hinges for beams and P-M-M hinges for columns.
