Popis: Most of the structures are subjected to dynamic loads during their life period such as wind, floods, earthquakes, impact, and blast loads, which affects the structural health. Structural Health Monitoring (SHM) can mitigate high repair costs by detecting and measuring the damage phenomena. In this study, Winkler’s concept-based prototype model has been prepared. Winkler’s model represents the soil medium as a system of identical but linearly elastic, mutually independent, discrete, closely spaced springs. An accelerometer is used to measure the actual vibration, by measuring acceleration in the x, y, z directions, which is converted to displacement, and finally translated into stiffness of the soil. This research study focused on the calculation of acceleration of the system for single and multiple human disturbances. All the results obtained indicated the presence of continuous noise vibrations.
