Reinforcement materials play a critical role in the seismic performance of concrete structures. This study explores the behavior of a G + 20 storyed building in seismic Zone 4 reinforced with fiber-reinforced polymer (FRP) rebars, comparing them to conventional steel reinforcement. Using response spectrum analysis, the research focuses on key parameters like base shear and maximum story displacement. Five rebar types are analyzed: steel, AFRP, BFRP, CFRP, and GFRP. Results show that AFRP rebars reduce base shear, while CFRP minimizes story displacement, indicating that FRP reinforcement can enhance structural resilience in earthquake-prone areas.

摘要

Reinforcement materials play a critical role in the seismic performance of concrete structures. This study explores the behavior of a G + 20 storyed building in seismic Zone 4 reinforced with fiber-reinforced polymer (FRP) rebars, comparing them to conventional steel reinforcement. Using response spectrum analysis, the research focuses on key parameters like base shear and maximum story displacement. Five rebar types are analyzed: steel, AFRP, BFRP, CFRP, and GFRP. Results show that AFRP rebars reduce base shear, while CFRP minimizes story displacement, indicating that FRP reinforcement can enhance structural resilience in earthquake-prone areas.
