Abstract
Monitoring the structural health of buildings is crucial to ensure their safety and reliability, especially for aging structures that are susceptible to corrosion and wear. This study focuses on monitoring the changes in the predominant frequency of an 8-story reinforced concrete building located in Nagaoka, Japan, under the influence of external factors. Vibration records obtained from velocity sensors are used to measure the vibrations induced by daily activities and environmental factors. Signal processing techniques are employed to analyze the data and determine the predominant frequencies of the building’s structure. The research findings reveal that the predominant frequencies of the building exhibit cyclic variations over time, closely associated with the impact of external factors, particularly temperature changes in the environment. These temperature changes contribute to fluctuations in the stiffness of the reinforced concrete structure at different surface temperatures.
