| dc.description.abstract | Indonesia is a country with a high level of disaster vulnerability due to its
unique location at the convergence of four tectonic plates (Indo-
Australian Plate, Eurasian Plate, Philippine Sea Plate, and Pacific
Plate). This geological setting results in numerous faults across
Indonesia, and even kalimantan the often-considered safest island has a
fault called the Tarakan Fault, stretching 100 km, located near the city of
Tarakan. Therefore, there is a need to assess the structural performance
of buildings in Tarakan City to determine whether they meet earthquake
resistance standards. The purpose of this research is to evaluate the
structural performance of a specific research subject, a hospital building
in the city of Tarakan. The evaluation employs the dynamic response
spectrum analysis method with a capacity spectrum based on ATC-40.
The analysis results include structural irregularities, inter-story drifts,
and diaphragm forces. The analysis results indicate that the building
exhibits irregularities in horizontal structure types 1a, 2, and 3, as well
as vertical structure types 1a and 2. The largest inter-story displacements
are measured at 0.0256 m in the x-direction and 0.0178 m in the y-
direction. The structural performance assessment using the performance-
based limit state and ultimate limit state methods concludes that the
building is secure and complies with the required criteria in both x and y
directions. According to ATC-40, the building's performance level based
on Maximum Total and Maximum Inelastic Drift Ratio is Immediate
Occupancy (IO). In conclusion, the building can withstand earthquakes
with minimal risk of casualties and damage. | en_US |
