Abstract (EN): <jats:p> Abstract The paper discusses Structural Health Monitoring (SHM) techniques for evaluating the integrity of cable-stayed bridges. Specifically, it explores the application of numerical model updating to detect and quantify structural damage. The method involves modifying system properties to match numerical-experimental responses. Notable researchers have studied this approach, aiming to detect and localize damages by altering dynamic properties like frequency, modal forms, and stiffness matrix. Through Finite Element Method (FEM) models, the study simulates various degrees of damage and evaluates responses against intact experimental tests. The analysis demonstrates the effectiveness of automatic updating in adjusting parameters for damage detection and localization, showing promise for practical application. The accuracy of the process depends on the extent of the studied damage. This study contributes to enhancing the SHM field by validating an automated method for detecting and assessing damage in cable-stayed bridges.</jats:p>
