Microwave Cylindrical Reflection Tomography Array for Damage Detection in Civil Structures
نویسنده
چکیده
The enhanced structural performance of Reinforced Concrete (RC) columns retrofitted by Fiber Reinforced Polymer (FRP) composite jackets, has been well demonstrated and an increasingly large number of bridge and building columns have been retrofitted with such jackets in the United States and elsewhere. However, seismic damage such as debonding between the jacket and the column that can considerably weaken the column remains a significant concern, as such damage cannot be visually identified. Poor bonding conditions, particularly the existence of large areas of voids and/or debonding, can significantly degrade the structural integrity and safety that could otherwise be attainable by jacketing (Haroun, et al, 1997).

Microwave Reflection Tomographic Array for Damage Detection of Civil Structures
Microwave tomographic imaging technology using a bifocusing operator has been developed in order to detect the internal voids/objects inside concrete structures. The imaging system consists of several cylindrical or planar array antennas for transmitting and receiving signals, and a numerical focusing operator is applied to the external signals both in transmitting and in receiving fields. An i...
متن کاملDamage detection of structures using modal strain energy with Guyan reduction method
The subject of structural health monitoring and damage identification of structures at the earliest possible stage has been a noteworthy topic for researchers in the last years. Modal strain energy (MSE) based index is one of the efficient methods which are commonly used for detecting damage in structures. It is also more effective and economical to employ some methods for reducing the degrees ...
متن کاملDamage Detection of Bridge by Rayleigh-Ritz Method
As a result of environmental and accidental actions, damage occurs in structures. The early detection of any defect can be achieved by regular inspection and condition assessment. In this way, the safety and reliability of structures can be increased. This paper is devoted to propose a new and effective method for detecting, locating, and quantifying beam-like structures. This method is based o...

متن کاملMulti-Damage Detection for Steel Beam Structure
Damage detection has been focused by researchers because of its importance in engineering practices. Therefore, different approaches have been presented to detect damage location in structures. However, the higher the accuracy of methods is required the more complex deliberations. Based on the conventional studies, it was observed that the damage locations and its size are associated with dynam...
