Iterative Damage Index Method for Structural Health Monitoring. (December 2009) Taesun You, B.S., Hanyang University, Seoul, South Korea Co-Chairs of Advisory Committee: Dr. Paolo Gardoni, Dr. Stefan Hurlebaus Structural Health Monitoring (SHM) is an effective alternative to conventional inspections which are time-consuming and subjective. SHM can detect damage early and reduce maintenance cost...

This paper proposes a structural damage detection method based on one-dimensional convolutional neural network (CNN). The can automatically extract features from data to detect damage. First, three-layer framework model was designed. Second, the displacement of each node collected under environmental excitation. Then, transformed into interlayer form dataset. Third, in order verify feasibility ...

A newly derived damage location algorithm is proposed to predict location of damage in offshore structures using changes in mode shapes from modal testing. This method decomposes elemental modal strain energy into two parts, and defines two damage indicators: axial damage indicator and transverse damage indicator. Analyzing the joint information of the two damage indicators can localize damage ...

Post-earthquake structural safety is evaluated manually by certified construction inspectors and structural engineers. They inspect visible damage (e.g. cracks) on critical structural elements (e.g. concrete columns). This process is time-consuming and costly. In order to automate this type of visual inspection, several damage detection methods have been developed. However, most of them can onl...
