Abstract This study analyzed the Serviceability and the structural safety of a high-rise building through Structural Health Monitoring(SHM) based on long-term acceleration data collected from March 2021 to December 2023. The target building, located on the coast, was monitored immediately after its completion. First, a serviceability evaluation was conducted throughout the monitoring period. Second, dynamic characteristics and long-term changes in natural frequencies were analyzed using Frequency Domain Decomposition(FDD) based on the acceleration response data. Finally, the long-term changes in the building's stiffness were estimated, and its structural safety was evaluated using System Identification(SI).
