Damage Detection with Auxiliary Subsystem [PDF]
Advances in Science and Technology, 2008 Among Non-Destructive Evaluation, vibration-based methods respond to the current ten- dency which is to integrate into the structure identication and monitoring systems; to this aim transducers and sensors are embedded with the mechanical system and driven by suitably designed electronic controllers.

Influence of changes in the prestress force on dynamic specifications of the prestressed concrete beam [PDF]
Numerical Methods in Civil Engineering, 2020 Pre-stress techniques tend to increase cross-sectional capacity and optimize design. Such features have made these techniques rather popular. Over time, these structures tend to fail, and the reduction of pre-stress force over the lifetime of the ...
