Abstract
Bridge monitoring is becoming increasingly important to transportation authorities around the globe. Both for traveler safety and for maintenance and repair planning. Structural deformation and deterioration problems faced by bridge authorities are very similar to those faced by dam and railroad authorities. Most large bridges hydroelectric and flood-control dams, were built from the 1930s through the 1950s, thus, is also aging. To regain cost competitiveness, trains are being designed for significantly higher speeds, requiring that the tracks conform to tighter standards for rail alignment The facts that many bridges are carrying greater average loads than predicted during their design have significantly increased the need over the past few years to monitor bridge performance.
Internationally.
This paper describes the monitoring system, developed for detecting the fracture in structures. The fracture that can be detected as an acoustic event by surface mounted sensors. Characteristics of the event provide information on the position of the event and its cause. There are some conventional methods for measuring structural vibration or displacement. These methods include measurement with accelerometer, measurement with a laser Interferometer.
This paper Attempts To Describe The Latest Technique namely, MONITORING USING GPS TECHNOLOGY.
This paper aims in the brief description of these techniques rather than the conventional methods. An attempt to describe the various aspects of these techniques is made through this paper
