Structural health monitoring is becoming more reliable as technology advances. There are many structures which are in use throughout cities and environments that requires constant attention due to fatigue of corrosion and environmental effects such as floods, earthquakes, or strong winds. This means that by advent of new damage detection technique, authorities can make sure that these vital structural elements such as road signs or traffic lights and so on are safe.
The important key to these techniques is that they must be simple and relatively inexpensive.
Therefore an attempt was done to use techniques in medical practice and adapt those to structural members.
In this article, the effectiveness of X-ray computed tomography in the inspection of urban structures and building structures is discussed. X-ray tomography is a non-destructive method based on X-ray absorption, which is widely used in the medical field. By using this method, it is possible to study and examine the internal structure of old structures in order to fix defects and maintain the safety of residents, as well as to maintain them as best as possible. For example, urban structures such as electric poles, traffic signs, which cause financial losses or even lives due to natural hazards or wear and tear every year. One of the features of this method is its high accuracy and speed in checking the member. Considering the capabilities of this method, in this research, using a baggage inspection device at the MehrAbad airport, a number of concrete and wooden samples were examined to identify defects such as cracks, holes, or knots in wooden samples. The results of the investigation are directly related to the power of the device and the duration of radiation to the sample. According to the results, defects such as cracks in concrete or knots in wood can be observed.
