Optimal Sensor Placement Techniques in Structural Health Monitoring Using Various Optimization Criteria
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 5
Abstract
Advanced engineering technologies are an emerging research area with multiple applications such as medical fields, home appliances, transportations, electrical systems, civil and mechanical systems, all manufacturing industry like chemical, fabrics, electronics equipment, structural like buildings, bridges, towers and so on, in our lives. It relies heavily on the pervasive civil infrastructure in which industrialized nations have huge investments. Malfunctioning of civil infrastructure has caused tremendous economic loss and claimed numerous human lives. To properly manage civil infrastructure, its condition or serviceability must be assessed and to be monitored. So nowadays, a sophisticated sensor usage in all fields is increased to monitor the condition of the structures. However, engineering structures are designed to last longer; they go beyond their design life span. Because these structures are combined with day today lives which leads to slow deterioration. Hence continuous monitoring of structures is necessary and it is monitored by using Structural Health Monitoring (SHM) systems. Considering cost, reliable data, accuracy of results, and computation time into account the proper deployment of sensors becoming a challenging task in SHM. There are several methods for optimal sensor placement and they are discussed in this paper with their deployment criteria. And also, this paper gives the historical background of SHM, the recent deployed sensor placements methods.
