Structural Health Monitoring: Plastic Material Assessment of Important Structures

Abstract

Digital image processing (DIP) uses the principle of photogrammetry and is also used to track features and associate their positions with a predefined coordinate system. Measurements are made by comparing a series of images taken at regular intervals. It can be used for many tests, including compression, tension, torsion, bending, and various combined loads for static and dynamic applications. A series of quasi-static tensile tests on plastic samples with four surface-mounted fibre optic probes showed that these probes had excellent linear strain behaviour over the entire range of applied loads. A free vibration test was also performed to evaluate the dynamics based on the cantilever configuration. The sensor response results show an excellent agreement with traditional sensors. This project deals with the comparison between maximum stress generated in building and bridge structures using MATLAB® software. The comparison of the behaviour of various types of cubes such as Plain Concrete beam (28 days), 5% Plastic waste as replacement of sand (28 days), 10% Plastic waste as replacement of sand (28 days), 12.5% Plastic waste as replacement of sand (28 days), and 15% Plastic waste as replacement of sand (28 days) The results found using different methods were comparable.
