In Pacitan, numerous non-engineered residential buildings can be seen despite the region’s susceptibility to earthquakes. This study aims to evaluate the performance of a structural frame representing the non-engineered building (NEB) in the region and determine the seismic intensity levels that can lead to varying degrees of damage. A pushover analysis was conducted to determine the overall structural capacity. Meanwhile, the performance point of the capacity spectrum method was used to determine the maximum earthquake that causes damage at various levels. The results show that the NEB structure could only withstand an earthquake load equivalent to 20.49% DBE before sustaining complete damage. By modifying the concrete compressive strength and stirrup spacing, the structure will experience complete damage after the earthquake load rises to 30.97% DBE.

摘要

In Pacitan, numerous non-engineered residential buildings can be seen despite the region’s susceptibility to earthquakes. This study aims to evaluate the performance of a structural frame representing the non-engineered building (NEB) in the region and determine the seismic intensity levels that can lead to varying degrees of damage. A pushover analysis was conducted to determine the overall structural capacity. Meanwhile, the performance point of the capacity spectrum method was used to determine the maximum earthquake that causes damage at various levels. The results show that the NEB structure could only withstand an earthquake load equivalent to 20.49% DBE before sustaining complete damage. By modifying the concrete compressive strength and stirrup spacing, the structure will experience complete damage after the earthquake load rises to 30.97% DBE.
