Consideration of simple approaches for structural health monitoring of structures in developing countries - An overview

Abstract

Structural health monitoring (SHM) is an advanced tool that revolutionizes the capability of a structure to act as a responsive system – detecting changes and responding with performance analysis. But, for developing countries, its need is undermined due to its costly deployment. However, contrary to the costly belief, its use is direly needed in densely populated developing countries. Therefore, a simple and cheaper technique (despite lesser precision and accuracy) can help in the early detection of damages in structures. Unfortunately, SHM implementation has been inadequate in developing countries, consequently, limited literature is available to assess. Therefore, the main goal of this literature review is to identify and analyze various SHM approaches and then propose a simple yet effective approach for achieving the basic amenities of SHM. By analyzing previous highly reputable journals, it was deduced that vibration-based approaches are the most cost-effective and simplistic to implement, which have resurged recently due to the increased use of computational tools that minimize extraneous data and provide efficient noise removal. The use of combination techniques in SHM can be cost-effective and accessible for developing nations, providing solutions for infrastructure sustainability.
