ABSTRACT
Eastern Indonesia, West Sulawesi Province the city of Mamuju is a region that is very prone to earthquakes. The earthquake in 2021 caused the Governor's Office Building to collapse completely. This condition caused the building structural systems in the city of Mamuju to suffer extensive damage and total collapse, particularly in the building columns. With this incident, building or house structures are provided with solutions to anticipate structural damage during a strong earthquake so that the structures can withstand and protect their occupants from the risk of earthquake hazards. One of the solutions in this article is to provide an additional external GFRP reinforcement placed on reinforced concrete columns aimed at increasing lateral stress. The use of external GFRP reinforcement is highly relevant in contemporary conditions with the advancement of material technology in concrete, namely Glass Fiber Reinforced Polymer (GFRP). The results of the tests on the circular concrete columns conducted in the structural laboratory using GFRP material as external reinforcement showed a very significant impact on axial strength. Thus, in the direct application to the 5-story grandstand building using external GFRP reinforcement on the reinforced concrete columns, it is shown that there are no overstressed structural element components.
