Special-function buildings are classified as high-risk due to their critical roles during and after earthquakes, requiring higher resilience than typical structures. According to FEMA 356, special-function buildings must achieve at least an Immediate Occupancy (IO) performance level under design-level earthquakes. This study assesses the seismic performance of special-function buildings in Jakarta constructed around 2012, using SAP2000 to compare structural responses under the 2012 and 2019 seismic codes. Analyzed parameters include base shear, inter-story displacement, drift ratio, and natural period. The building has a natural period of 2.5773 s, with a 37.54% increase in spectral acceleration and a 15% rise in base shear under the 2019 code. While it meets current structural standards with an Immediate Occupancy performance level, inter-story displacement on the 6th floor reached 98% of the allowable limit. This indicates that any increase in seismic intensity could shift the performance level from Immediate Occupancy to Life Safety, reducing the building's functionality during emergencies. Therefore, structural strengthening is recommended, and further research is needed to identify effective retrofitting strategies.

摘要

Special-function buildings are classified as high-risk due to their critical roles during and after earthquakes, requiring higher resilience than typical structures. According to FEMA 356, special-function buildings must achieve at least an Immediate Occupancy (IO) performance level under design-level earthquakes. This study assesses the seismic performance of special-function buildings in Jakarta constructed around 2012, using SAP2000 to compare structural responses under the 2012 and 2019 seismic codes. Analyzed parameters include base shear, inter-story displacement, drift ratio, and natural period. The building has a natural period of 2.5773 s, with a 37.54% increase in spectral acceleration and a 15% rise in base shear under the 2019 code. While it meets current structural standards with an Immediate Occupancy performance level, inter-story displacement on the 6th floor reached 98% of the allowable limit. This indicates that any increase in seismic intensity could shift the performance level from Immediate Occupancy to Life Safety, reducing the building's functionality during emergencies. Therefore, structural strengthening is recommended, and further research is needed to identify effective retrofitting strategies.
