Structural health monitoring (SHM) involves the observation and analysis of a system over time using periodically sampled response measurements to monitor changes to the material and geometric properties of engineering structures such as bridges and buildings. In an operational environment, structures degrade with age and use.
A standard geodetic monitoring instrument in the Freeport open pit mine, Indonesia GNSS reference station antenna for structural monitoring of the Jiangying Bridge. Measuring devices (or sensors) can be sorted in two main groups: geodetic and geotechnical sensors. Both measuring devices can be seamlessly combined in modern deformation monitoring.
Since the late 1980s the structural health assessment and monitoring of bridges represented a critical topic in the field of civil infrastructure management. [6] In the 1990s, the Federal Highway Administration (FHWA) of the United States promoted and sponsored PONTIS and BRIDGEIT, two computerized platforms for viaduct inventory and monitoring named BMSs.
The value of structural health information is the expected utility gain of a built environment system by information provided by structural health monitoring (SHM).The quantification of the value of structural health information is based on decision analysis adapted to built environment engineering.
This framework is about using structural-dynamics based methods to address the existing challenges in the field of structural health monitoring (SHM). [1] It makes no ad hoc assumptions regarding the physical behavior at the damage location such as adding fictitious springs or modeling changes in Young's modulus.
Fault detection, isolation, and recovery (FDIR) is a subfield of control engineering which concerns itself with monitoring a system, identifying when a fault has occurred, and pinpointing the type of fault and its location. Two approaches can be distinguished: A direct pattern recognition of sensor readings that indicate a fault and an analysis ...
A growing property insurance crisis may make it hard to get a mortgage in parts of the country in the coming decades, Federal Reserve Chairman Jerome Powell said Tuesday in testimony before Congress.
The Illinois Structural Health Monitoring Project was founded in 2002 when Professor Bill F. Spencer, director of the Smart Structures Technology Laboratory, and Professor Gul Agha, director of the Open Systems Laboratory, began a collaborative effort between the two laboratories at the University of Illinois at Urbana–Champaign.
