Abstract:

This study analyzes the seismic vulnerability of the Al-Wildan International Islamic School dormitory building in Sekarbela District, Mataram City, which is situated in a soft-soil zone with high seismic amplification potential. The methodology combines microtremor data analysis (HVSR) and structural modeling using ETABS software. HVSR results indicate a dominant ground frequency of 0.75 Hz, which is close to the structure’s natural period (0.637 seconds in the X-direction), suggesting the potential for partial resonance. The seismic amplification factor reaches 6.22, significantly increasing the building's dynamic response. Structural analysis shows that most primary columns meet the axial and shear strength criteria; however, two columns (Column 6 and Column 7) fail to satisfy flexural capacity requirements, with Column 7 exhibiting the highest lateral displacement at 0.0416 m. Meanwhile, beam elements remain structurally safe under flexural and shear demands but exhibit increased deformation due to local soil effects. These findings emphasize the importance of incorporating site-specific soil characteristics in structural design, especially in earthquake-prone areas. This study recommends adopting microzonation-based seismic design and implementing enhanced energy dissipation systems to improve structural resilience during seismic events.
