How will you examine Structural failure of a bridge if damaged is not visible?

Question

Accepted Answer

To examine structural failure of a bridge when damage is not visible, non-destructive testing methods can be used.

Non-destructive testing methods such as ultrasonic testing, radiographic testing, and magnetic particle testing can be employed.
Ultrasonic testing involves sending high-frequency sound waves through the bridge to detect internal flaws or defects.
Radiographic testing uses X-rays or gamma rays to create images of the bridge's internal structure, revealing any hidden damage.
Magnetic particle testing is used to identify surface and near-surface defects by applying magnetic fields and inspecting for magnetic particles.
Other methods like ground-penetrating radar, acoustic emission testing, and infrared thermography can also be utilized.
These non-destructive testing techniques help identify structural issues that may not be visible to the naked eye.

first we need to look if defect is in sub structure or superstructure we will have to take a quick survey of project and record all the dimensions and match them with original data, the we will find out location of damage
