RISDetectability of damage by a new modal sensitivity function
few dynamic
and physical characteristics for formulating the sensitivity matrix. A high compatibility with
incomplete modal parameters is another innovation of the proposed sensitivity function that
makes it as an applicable...
A numerical damage identification approach by direct sensitivity of orthogonality conditions via stiffness modification index
as well as modal parameters consist of natural frequencies and mode shapes must be utilized. For damage assessment, two numerical structures as discrete and continuous dynamic systems are modeled. First, the extent of induced damage is estimated in a...
Structural Damage Detection by Sensitivity Analysis of Vibrational Response in Civil and Architectural Buildings
This study investigates the use of vibrational response of structure known as modal parameters, for identification of damage in the civil and architectural buildings. The vibrational response is defined as modal parameters that contain of mode shape...
Application of Hopfield neural network to structural health monitoring
Structural health monitoring (SHM) using artificial neural networks has received increasing
attention due to robustness of neural networks, better performance compared to conventional
damage detection methods, ...
Damage Detection of Plane Strain/Stress Problems using Modal Data
شناسایی آسیب در مسائل تنش– کرنش مسطح بااستفاده از داده‌های مودال
وجود آسیب یا ترک در سازهها باعث تغییر در پارامترهای مودال می‌شود و فرکانسهاي طبیعی و شکل مودهای ارتعاشی آنها را تحت تأثیر قرار می‌دهد؛ بنابراین میتوان از تغییر پارامترهای مودال، برای شناسایی آسیب در سازهها استفاده ...
