This output changes proportionally to the force applied to the load cell. AE sensors are able to pick up the stress waves propagated to the material’s surface. [12][13] This paradigm can be broken down into four parts: (1) Operational Evaluation, (2) Data Acquisition and Cleansing, (3) Feature Extraction and Data Compression, and (4) Statistical Model Development for Feature Discrimination. The development of effective structural health monitoring (SHM) methods has gained traction amongst the research community in recent years. Damage accumulation testing, during which significant structural components of the system under study are degraded by subjecting them to realistic loading conditions, can also be used to identify appropriate features. Load cells have been employed for a variety of applications that demand accuracy and precision. Ooijevaar T.H., Rogge M.D., Loendersloot R., Warnet L., Akkerman R., Tinga T..

Inclinometers are designed to measure horizontal subsurface deformation in a borehole when slope stability is a concern for natural slopes, constructed cut/fill slopes, and deep fill projects. The use of multiple strain gauges enables a more precise evaluation of strain on the surface being measured [Shahsavari et al 2019]. (2010). In the last ten to fifteen years, SHM technologies have emerged creating an exciting new field within various branches of engineering.

These processes can be implemented through hardware or software and, in general, some combination of these two approaches will be used. Rocco Ditommaso, Marco Mucciarelli, Felice C. Ponzo (2010). Structural health monitoring heavily relies on collecting accurate and high quality real-time measurements of structural element condition, communicating this information with control system, and signalling necessary warnings should an irregular pattern is ever observed. L1H8C1. Pingback: Bridge Diagnostic Load Testing | FPrimeC Solutions. Ponzo F.C., Auletta G., Ditommaso R. & Mossucca A. Because data can be measured under varying conditions, the ability to normalize the data becomes very important to the damage identification process. It is mandatory to procure user consent prior to running these cookies on your website. An accelerometer is an electromechanical device used for measuring acceleration forces through single or multi-axis directions. When environmental or operational variability is an issue, the need can arise to normalize the data in some temporal fashion to facilitate the comparison of data measured at similar times of an environmental or operational cycle. Sensors for structural health monitoring are designed to facilitate the monitoring process, and enabling maintenance engineers with decision-making tools, which will ensure the safety of the facility, and the public. Commonly known as Structural Health Assessment (SHA) or SHM, this concept is widely applied to various forms of infrastructures, especially as countries all over the world enter into an even greater period of construction of various infrastructures ranging from bridges to skyscrapers.
