Abstract
The geographical location of Indonesia on the Ring of Fire makes it prone to earthquakes. Frequent earthquakes cause failures in construction. Construction failures must be repaired to restore the strength of the structures to their original or even higher levels. One type of structural reinforcement is Fiber Reinforced Polymers (FRP). FRP can enhance the strength of beams damaged by earthquakes, alter the structural failure mode, increase load-carrying capacity, and prolong plastic hinges in beam elements. This study recommends using FRP to reinforce concrete structures, particularly beams. The first stage of the research involves experimental testing on a prototype not wrapped with FRP. After reaching peak strength and experiencing failure, then the prototype is covered with FRP. Subsequently, the prototype is retested until it gets peak strength and experiences failure again. Both specimens are subjected to monotonic loading, which is simulated as cyclic loading. Data processing is performed by analyzing the results of the experimental testing on both prototypes. The processed data includes crack patterns in the beams, cyclic load capacity, displacement, strain of concrete, strain in the primary reinforcement, and strain in the stirrup reinforcement.
