An effective approach for damage identification in beam-like structures based on modal flexibility curvature and particle swarm optimization

In this paper, a computationally simple approach for damage localization and quantification in beam-like structures is proposed. This method is based on using modal flexibility curvature (MFC) and particle swarm optimization (PSO) algorithm. Analytical studies in the literature have shown that changes in the modal flexibility curvature can be considered as a sensitive and suitable criterion for...

Genetic Algorithm-based Approach for Bayesian Damage Identification Using Spectral Density Analysis in Beam-like Structures

This paper, which is a part of an ongoing research study, describes a Genetic Algorithm-based approach towards a global damage identification framework for the continuous/periodic monitoring of civil structures. In order to localise and estimate the severity of damage regions, a one stage model-based Bayesian probabilistic damage detection approach is proposed. The method is based on response p...

IMPROVED BAT ALGORITHM FOR OPTIMUM DESIGN OF LARGE-SCALE TRUSS STRUCTURES

Deterring the optimum design of large-scale structures is a difficult task. Great number of design variables, largeness of the search space and controlling great number of design constraints are major preventive factors in performing optimum design of large-scale truss structures in a reasonable time. Meta-heuristic algorithms are known as one of the useful tools to d...

Structural damage identification in laminated structures using FRF data

A damage identification technique based on frequency response functions (FRF) sensitivities is presented. This technique leads to a set of linear equations, which is solved using an algorithm that constrains the solution to be physically admissible. Damage simulation and identification on a laminated rectangular plate is performed. The influence of the number of natural frequencies and mode sha...

Damage Detection in Beam-like Structures using Finite Volume Method

In this paper the damage location in beam like-structure is determined using static and dynamic data obtained using finite volume method. The change of static and dynamic displacement due to damage is used to establish an indicator for determining the damage location. In order to assess the robustness of the proposed method for structural damage detection, three test examples including a static...
