Abstract

Base isolation is a design strategy applied to increase the resistance of structures to strongearthquakes by separating the superstructure from the ground. The purpose of this study wasto analyze the performance of the structure using the base insulator HDRB compared to thefixed base structure. The research method uses a response spectrum method based on SNI1726:2019. Structural performance is evaluated based on the results of structural analysis inthe form of drift, displacement, base shear forces and forces in structural elements. The casestudy discussed in this study is the 12-storey Central Jakarta MRT Hub building with 2basements. The results of the analysis show that the use of base isolators can increase thestructure's ability to carry the base shear force by 61% in the X direction and by 62% in the Ydirection, reduce displacement, reduce the drift between floors by an average of 43% in the Xdirection and 40% in the Y direction. Y direction and reduce the moments and shear forces ofthe beam and column elements under consideration.
