Smart structural health monitoring in civil engineering: A survey

Abstract

Structural health monitoring (SHM) technologies for tracking and assessing socially and historically constructed long-haul spans was being increasingly recognized, and several government officials have realized the importance of the methodology. The article reviews recent advance of the SHM technologies in order to long-span bridges. A SHM framework is implemented to deploy. The research design and quality evaluation involving modal recognition techniques, image processing approaches, and hazard detection systems were then checked and presented. This research incorporates a developing capacity tool in combination with a low- and mid-index demonstrable evaluation tool for bridge architectural condition monitoring. The strength of concrete, stiffness of the steel beam surface, density of the top surface of the hollow plate, crack propagation, cover hardness of metal bars etc.From the examples, the open issues and recent developments for a SHM system have been addressed.
