摘要：Over the past two decades, laboratory tests have suggested that fibre reinforced polymer (FRP) bars can replace steel bars as internal reinforcement in concrete structures, especially those are subjected to aggressive environments. FRP bars has potential for replacing steel bars as these material are corrosion-resistant and have high tensile strength, make it suitable for use as structural reinforcement. Unfortunately, the application of FRP for reinforcing structures in Indonesia is dubious. This paper aims to study the behaviour of reinforced concrete (RC) building reinforced with Carbon FRP (CFRP) and steel bars. The observed building was designed for Pekanbaru, according to SNI 2847:2013 for design of structural RC with steel bars reinforcement and the ACI 440.1R-15 for design and construction of structural RC with FRP bars. Two reinforcedconcrete moment resisting frames, extracted from 6 storey heights building with rectangular floor plan, were designed for the city of Pekanbaru. The building had the typical storey height of 3.6 m except for the first floor where the column length was 4.0 m. Two frames were investigated, including the frame without (Frame A) and with shear wall (Frame B). Pushover analysis was conducted to establish the design force and the design deformation demands. The results show that the amount of bar areas needed for reinforcing the building with CFRP bars was significantly reduced. Moreover, the maximum forced demand attained for the building reinforced with CFRP bars were enhanced by about 1.9 times compared to that of reinforced with steel bars.
