پایش سلامت دکلهای فولادی خرپایی جهت شناسایی شدت و مکان آسیب با استفاده از شاخصهای انتگرالی و تفاضلی

This study focuses on structural health monitoring to detect, locate, and assess the severity of damage. The proposed method utilizes Transmissibility Function in a case study of a steel truss structure located in Germany, based on its acceleration responses recorded over time. Transmissibility Function are calculated using acceleration data from both undamaged and damaged states. These Transmissibility Functions are derived by computing the cross-power spectral density function and the power spectral density function of the acceleration data, followed by their ratio. The employed method allows for simultaneous analysis and comparison of all outputs of the transfer functions and damage indices obtained from accelerometer sensors. The case study results demonstrate the method's effectiveness in detecting and locating damage. Additionally, the damage severity index significantly aids in determining the extent of structural damage.
