Crack Detection and Classification in Concrete Structure
This paper presents crack detection in concrete structure based on fuzzy logic. Safety inspection of concrete structures is very important since it is closely related with the structural health and reliability. Automated structural health monitoring system becomes necessity in recent years that encourages various researches to be going on in this area. Cheap availability of digital cameras make...
متن کاملTapered Polymer Fiber Sensors for Reinforced Concrete Beam Vibration Detection
In this study, tapered polymer fiber sensors (TPFSs) have been employed to detect the vibration of a reinforced concrete beam (RC beam). The sensing principle was based on transmission modes theory. The natural frequency of an RC beam was theoretically analyzed. Experiments were carried out with sensors mounted on the surface or embedded in the RC beam. Vibration detection results agreed well w...
متن کاملCrack Detection in Fibre Reinforced Plastic Structures Using Embedded Fibre Bragg Grating Sensors: Theory, Model Development and Experimental Validation
In a fibre-reinforced polymer (FRP) structure designed using the emerging damage tolerance and structural health monitoring philosophy, sensors and models that describe crack propagation will enable a structure to operate despite the presence of damage by fully exploiting the material's mechanical properties. When applying this concept to different structures, sensor systems and damage types, a...
متن کاملMonitoring of Crack Propagation in Concrete Using Embedded Piezoelectric Transducers
A concrete structure can be subject to several factors that may damage it during its service life. These factors are either be climatic, chemical or accidental. The security requirements are more and more speci c and severe. To ensure the safety of a structure, it is important to know its state and the properties of the materials that make it up. For this purpose, many tests has been developed....
متن کاملCRACK DETECTION IN CONCRETE BEAM USING OPTIMIZATION METHOD
Structural damage detection is a field that has attracted a great interest in the scientific community in recent years. Most of these studies use dynamic analysis data of the beams as a diagnostic tool for damage. In this paper, a massless rotational spring was used to represent the cracked sections of beams and the natural frequencies and mode shape were obtained. For calculation of rotational...
