Abstract
Structural health monitoring is a method which is used to detect the damages in civil engineering structures that helps in developing the techniques and to identify, locate and classify damage in structures. This complete analysis of bridges helps in obtaining an effective maintenance plan that offers sustained service life of the structures. The present study focuses on implementation, analysis and design of a scaled model of truss bridge by using STAAD Pro software. The scaled model of truss bridge is subjected to a dynamic vibration by a vibrator and is measured using accelerometer sensor. The response under these vibrations are recorded with the help of telemetry software in terms of time domain graph. The graph induced in MATLAB is used to convert time domain graph to frequency domain graph. The experimentation is followed by replacing the healthy structure with the damage structure. The structural graph responses obtained give a reduction in the natural frequency when it is compared to a healthy structure.
