EFFICIENCY EVALUATION OF PROPOSED OBJECTIVE FUNCTIONS IN STRUCTURAL DAMAGE DETECTION BASED ON MODAL STRAIN ENERGY AND FLEXIBILITY APPROACHES
Civil infrastructures such as bridges and buildings are prone to damage as a result of natural disasters. To understand damages induced by these events, the structure needs to be monitored. The field of engineering focusing on the process of evaluating the location and the intensity of the damage to the structure is called Structural Health Monitoring (SHM). Early damage prognosis in structures...
متن کاملModal Strain Energy Based Damage Detection Using Multi-Objective Optimization
Modal strain energy has been reported by researchers as one of the sensitive physical measures that can be used as a damage index in structural health monitoring. Inverse problem-solving based approaches using single-objective optimization algorithms are also one of the promising damage identification methods. However, integration of these potential methods is currently limited with partial suc...
متن کاملDamage detection of structures using modal strain energy with Guyan reduction method
The subject of structural health monitoring and damage identification of structures at the earliest possible stage has been a noteworthy topic for researchers in the last years. Modal strain energy (MSE) based index is one of the efficient methods which are commonly used for detecting damage in structures. It is also more effective and economical to employ some methods for reducing the degrees ...
متن کاملModal parameters based structural damage detection using artificial neural networks - a review
One of the most important requirements in the evaluation of existing structural systems and ensuring a safe performance during their service life is damage assessment. Damage can be defined as a weakening of the structure that adversely affects its current or future performance which may cause undesirable displacements, stresses or vibrations to the structure. The mass and stiffness of a struct...
