Multi-Damage Detection for Steel Beam Structure
Damage detection has been focused by researchers because of its importance in engineering practices. Therefore, different approaches have been presented to detect damage location in structures. However, the higher the accuracy of methods is required the more complex deliberations. Based on the conventional studies, it was observed that the damage locations and its size are associated with dynam...
متن کاملDamage Detection of Axially Loaded Beam: A Frequency-Based Method
The present study utilizes an analytical method to formulate the three lowest modal frequencies of axially-loaded notched beam through both crack location and load level in a specific format that can be used in existing frequency-based crack-identification methods. The proposed formula provides a basis to shift into two states, one with axial loading and the other without any loading whatsoever...

متن کاملDamage 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...
متن کاملModeling Curvature Damage Surface For Damage Detection In Cantilever Beam
A damage detection method is presented for the identification and quantification of damage. The proposed method uses finite element method to extract modal parameters of cracked and intact cantilever beam. The damage is simulated by fracture mechanics concept by introducing cracked elements at different locations with predetermined magnitude of depth. The curvature response function, function o...
