An Efficient Damage Identification Method for Simply Supported Beams Based on Strain Energy Information Entropy [PDF]

open access: yesAdvances in Materials Science and Engineering, 2020
Concrete simply supported beams are widely used in small- and medium-sized bridges. Hinged slabs and joints are damaged in service easily, as they are the main load-carrying members of bridge.

Research on load bearing performance recovery method of a RC simply-supported beam bridge [PDF]

open access: yesE3S Web of Conferences, 2021
The load-bearing performance of a RC simply supported beam bridge was comprehensively detected and evaluated. The appearance detection results show that there is a large area of damaged and exposed reinforcement in the main girder and diaphragm plate of ...

A simple method for enhanced vibration-based structural health monitoring [PDF]

open access: yes, 2011
This study suggests a novel method for structural vibration-based health monitoring for beams which only utilises the first natural frequency of the beam in order to detect and localise a defect.

Experimental and computational study on dynamic analysis of cracked simply supported structures under moving mass

open access: yesFracture and Structural Integrity, 2022
In this study, the influences of crack parameters like crack location from the left end, crack height, number of cracks and the magnitude of mass and the velocity of the transit load on the vertical displacements of the cracked simply supported beams ...

An Analytical Method for Determining the Residual Strength of Reinforced Concrete Beam-Slab Specimens

open access: yesFrontiers in Built Environment, 2022
This paper proposed one new method to determine the residual ultimate loads of the fire-damaged beam-slab specimens. Based on the conventional yield line method, the stiffness and deflection of the edge beam was considered to establish the theoretical ...

Damage Identification Method and Uncertainty Analysis of Beam Structures Based on SVM and Swarm Intelligence Algorithm

open access: yesBuildings, 2022
A two-stage damage identification method for beam structures based on support vector machine and swarm intelligence optimization algorithms is proposed. First, the frequencies and mode shapes of the beam structure are obtained using the smooth orthogonal

Damage detection in simply supported beams using machine learning

open access: yesStudia Universitatis BabeČ™-Bolyai Engineering, 2022
The more our infrastructure is aging, the risk of structural failure is higher, making the detection of damage using modal parameters a very important factor that can be applied in structural health monitoring. The most desired way to assess the health of engineering structures during operation is to use non-destructive vibration-based methods.

Behavior and flexural strength of fire-damaged high-strength reinforced rectangular concrete beams with tension or compression zones exposed to fire repaired with CFRP sheets

open access: yesCase Studies in Construction Materials, 2021
Motivated by the fact that fire is one of the most dangerous threats to buildings and structures, the main goal of this research is to determine the residual flexural capacity of high-strength simply supported reinforced concrete beams after exposing the
