“…Therefore, it is crucial to install early warning systems to monitor and control therefore to assess the health of important structures. In many countries such as Japan [7] and Australia [8], SHM systems are widely used in critical structures and the necessary software and hardware components are developed by these countries. This issue is taken into consideration and its popularity is increasing day by day also in Istanbul [9] and in the world [10][11][12][13][14][15][16][17].…”

Energy harvesting, which is a popular subject, can be defined as the use of energy released by environmental forces such as earth-shaking, wind, etc. Civil engineering structures also harvest energy in a different way. Thanks to this energy harvest, the modal properties of structures such as natural frequency, mode shape can be estimated from the response histories taken from the structure. Modal properties of the structure give an impression of the health of the building. However, an important question comes to mind: Did the energy harvesting of the structures sufficiently drive the modes used to detect damage? Or in other words, has it exceeded a certain amount of energy to drive the modes? If the mode in question is not sufficiently excited, it can be interpreted as a harbinger of damage for an undamaged structure in the analysis using these modes. For this reason, it is an important issue to determine to what extent the modes are driven. In this study, the aforementioned subject has been explored with the title "Mode Excitation Energy" using the modal plot method.
