DAMAGE DETECTION FOR RIGID FRAMED VIADUCT BY USING PERCUSSION TEST

STRUCTURAL DAMAGE DETECTION BY USING TOPOLOGY OPTIMIZATION FOR PLANE STRESS PROBLEMS

This paper aims to introduce topology optimization as a robust tool for damage detection in plane stress structures. Two objective functions based on natural frequencies and shape modes of the structure are defined to minimize discrepancy between dynamic specifications of the real damaged structure and the updating model. Damage area is assumed as a porous material where amount of porosity sign...

Detection of Earthquake-Induced Damage in a Framed Structure Using a Finite Element Model Updating Procedure

Damage of a 5-story framed structure was identified from two types of measured data, which are frequency response functions (FRF) and natural frequencies, using a finite element (FE) model updating procedure. In this study, a procedure to determine the appropriate weightings for different groups of observations was proposed. In addition, a modified frame element which included rotational spring...

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...
