Jun 05,2020 Bridge Damage Severity Quantification Using Multipoint#0183;We evaluate our framework using lab-scale experiments with two different bridges.On average,our framework achieves 94%,97% and 84% accuracy for damage detection,localization and quantification,respectively.within one damage severity level.Structural Damage Localization and Quantification BasedVibrations of complex structures such as bridges mostly present nonlinear and non-stationary behaviors.Recently,one of the most common techniques to analyze the nonlinear and non-stationary structural response is HilbertHuang Transform (HHT).This paper aims to evaluate the performance of HHT based on complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN) technique Structural Damage Detection in Real Time Implementation Mar 22,2017 Bridge Damage Severity Quantification Using Multipoint#0183;Abstract.Most of the classical structural damage detection systems involve two processes,feature extraction and feature classification.Usually,the feature extraction process requires large computational effort which prevent the application of the classical methods in real-time structural health monitoring applications.

LESSONS LEARNT FROM CANTERBURY EARTHQUAKES

The criterion adopted to obtain a global damage index (GDI) was to sum the severity ratings of the different damage categories.Therefore,for example,a bridge with a damage severity of 2 for the deck,and 3 for the bearings would be given a GDI = 5.In order to rate the bridge,four damage classes were defined a GDI ranging from 1 to 2 wasDevelopment of a Machine Learning-Based Damage It is necessary to assess damage properly for the safe use of a structure and for the development of an appropriate maintenance strategy.Although many efforts have been made to measure the vibration of a structure to determine the degree of damage,the accuracy of evaluation is not high enough,so it is difficult to say that a damage evaluation based on vibrations in a structure has not been Damage identification in beam-type structures usingBased on pseudo strain energy density (PSED) and grey relation coefficient (GRC),an index is proposed to locate the damage of beam-type structures in time-domain.The genetic algorithm (GA) is utilized to identify the structural damage severity of confirmed damaged locations.Furthermore,a systematic damage identification program based on GA is developed on MATLAB platform.
