Damage Identification of Simply-Supported Beam Bridge Based on Deflection Influence Line

open access: yesIOP Conference Series: Earth and Environmental Science, 2021
Abstract In order to extend the service life of the bridge and reduce the occurrence of catastrophic accidents, it is necessary to monitor and identify the damaged parts of the bridge in time. In this paper, the author firstly proposes a basic theory of deflection influence line, then analyzes the calculation basis and proposes a method ...

Flexural Strength of Damaged RC Beams Repaired with Carbon Fiber-Reinforced Polymer (CFRP) Using Different Techniques

open access: yesFibers, 2023
In this study, an experimental program was developed to investigate the flexural behavior of pre-damaged reinforced concrete (RC) beams that had been repaired and strengthened using carbon fiber-reinforced polymer (CFRP) laminates under a monotonic load.

Prediction of the behavior of reinforced concrete deep beams with web openings using the finite ele

open access: yesAlexandria Engineering Journal, 2014
The exact analysis of reinforced concrete deep beams is a complex problem and the presence of web openings aggravates the situation. However, no code provision exists for the analysis of deep beams with web opening.

Effective filtering of modal curvatures for damage identification in beams [PDF]

open access: yes, 2017
In this work, we investigate the effectiveness of a damage identification technique recently proposed in [1] and assess how it is affected by the number and position of the sensors used.

Damage localization and quantification in simply supported beams using static test data

open access: yesJournal of Physics: Conference Series, 2017
A novel simple method using static test data for damage detection, localization, and quantification in beams is presented in this paper. The method is based on the change of the deflections of the beam between a reference and a damaged state. For simply supported beams with a single damage, the maximum value of the change of deflections indicates the ...
