Structural Health Monitoring and Seismic Impact Assessment
The goals of seismic impact assessment can be achieved by seismic monitoring systems and seismic impact simulator. Seismic monitoring system, for the purpose of hazard analysis, local site effects analysis, vulnerability analysis, and estimation of loss, is one application of SHM in earthquake engineering. A prototype, conceptual seismic impact simulator integrating SHM, FEM, GIS, and Virtual R...
متن کاملVirtual Visual Sensors and Their Application in Structural Health Monitoring
The ability to deploy an array of sensors efficiently and effectively is a key factor in sensor network design. Sensor installation and management can be difficult in practice for a variety of reasons: a hostile environment, high labour costs and bandwidth limitations. We propose Virtual Visual Sensors (VVS) as a convenient physical sensor substitute for certain problems and environments. Major...
متن کاملApplication of Wireless Sensors for Structural Health Monitoring And Control
Wireless sensors have been proposed for use in structural health monitoring systems because they offer low-installation costs and automated data processing functionality. To validate the performance of the proposed WiMMS (wireless modular monitoring system) on the vibration measurement of large-scale civil structures, a three-story half-scale steel structure is instrumented with a wireless moni...
متن کاملDesign and Performance of Wireless Sensors for Structural Health Monitoring
Wireless sensors can be realized by integrating a sensor with a passive commercial radio-frequency identification (RFID) chip. When activated, the chip responds with a digitally encoded signal that not only identifies the sensor but also contains information about the sensor state. Two devices have been developed to date: a temperature-threshold indicator and a chloride-threshold indicator. Thi...
متن کاملStructural health monitoring using active sensors and wavelet transforms
Health monitoring methods using active sensors (e.g. piezoelectric transducers) and wavelet transforms are being developed in the Department of Mechanical Engineering at the University of South Carolina. In these methods, wave propagation signals are collected using arrays of piezoelectric transducers placed on or embedded in a structure. The collected signals are analyzed using appropriate wav...
