This brief covers the emerging area of wireless sensor network (WSN)-based structural health monitoring (SHM) systems, and introduces the authors’ WSN-based platform called SenetSHM. It helps the reader differentiate specific requirements of SHM applications from other traditional WSN applications, and demonstrates how these requirements are addressed by using a series of systematic approaches. The brief serves as a practical guide, explaining both the state-of-the-art technologies in domain-specific applications of WSNs, as well as the methodologies used to address the specific requirements for a WSN application. In particular, the brief offers instruction for problem formulation and problem solving based on the authors’ own experiences implementing SenetSHM. Seven concise chapters cover the development of hardware and software design of SenetSHM, as well as in-field experiments conducted while testing the platform. The brief’s exploration of the SenetSHM platform is a valuable feature for civil engineers designing their own similar SHM products, and the various concrete examples of problem formulation and algorithm design will make this an essential read for practitioners, researchers and students alike.

The gradual deterioration of bridges, buildings and other civil engineering structures invokes the need to develop structural health monitoring (SHM) systems to monitor the well-beings of structures. Dozens of wired sensing, processing and monitoring mechanisms have been implemented and widely deployed. However, they are complex to handle and expensive. Wireless sensor networks (WSNs), on the other hand, can easily be deployed with low-cost. But, care needs to be taken while designing data processing algorithms due to their computational limitations: low memory, power consumption, etc. In this book we implement an efficient solution for SHM using WSNs.

This 2-volume set of books, comprising over 2,700 total pages, presents 325 fully original presentations on recent advances in structural health monitoring, as applied to commercial and military aircraft (manned and unmanned), high-rise buildings, wind turbines, civil infrastructure, power plants and ships. One general theme of the books is how SHM can be used for condition-based maintenance, with the goal of developing prediction-based systems, designed to save money over the life of vehicles and structures. A second theme centers on technologies for developing systems comprising sensors, diagnostic data and decision-making, with a focus on intelligent materials able to respond to damage and in some cases repair it. Finally the books discuss the relation among data, data interpretation and decision-making in managing a wide variety of complex structures and vehicles. More recent technologies discussed in the books include SHM and environmental effects, energy harvesting, non-contact sensing, and intelligent networks.Material in these books was first presented in September, 2011 at a conference held at Stanford University and sponsored by the Air Force Office of Scientific Research, the Army Research Office, the Office of Naval Research and the National Science Foundation. Some of the highlights of the books include: SHM technologies for condition-based maintenance (CBM) and predictive maintenance Verification, validation, qualification, data mining, prognostics systems for decision-making Structural health, sensing and materials in closed-loop intelligent networks Military and aerospace, bioinspired sensors, wind turbines, monitoring with MEMS, damage sensing, hot spot monitoring, SHM and ships, high-rise structures Includes a fully-searchable CD-ROM displaying many figures and charts in full color

Wireless Sensor Networks (WSN) for Structural Health Monitoring (SHM) applications can provide the data collection necessary for rapid structural assessment after an event such as a natural disaster puts the reliability of civil infrastructure in question. Unfortunately, there are many technical challenges associated with employing such a WSN in civil infrastructure for operation over multiple decades with maintenance costs low enough to justify the integration of such a WSN into a given structure. The technical challenges include ensuring power is maintained at the sensor nodes, reducing installation and maintenance costs, and automating the collection and analysis of data provided by a wireless sensor network. In this work a new WSN paradigm to address these challenges is presented. The new WSN paradigm is called the "mobile host" WSN. In a mobile host WSN, the sensor nodes are placed on the structure with no internal electrical power source. Instead the node is equipped with hardware to collect energy delivered to it wirelessly by a mobile host on an as-needed basis in order to perform its intended data acquisition and interrogation functions. When an event of interest occurs which might compromise the integrity of the structure, the sensor nodes capture relevant data from the event. In order to collect the data captured by the sensor network, a "mobile host" is sent to each sensor node and wirelessly charges it up. Once the sensor node is fully charged, it turns on and transmits its data wirelessly to the mobile host. The mobile host receives and stores the data and then implements appropriate structural health monitoring (SHM) data interrogation algorithms. If deemed necessary the mobile host then proceeds to interrogate other sensor nodes of interest on the structure. In this way a remote system is presented that can then be used to make a health assessment of the structure. This dissertation addresses the research challenges encountered when implementing a mobile host Won. A sensor node (THINNER) capable of collecting data tirelessly in the absence of electrical power was developed. A peak displacement and bolted joint p reload sensor capable of interfacing with the THINNER sensor node were designed and implemented. A wireless energy delivery package capable of being carried by an airborne mobile host was developed. Lastly, the system engineering required to implement the overall sensor network was carried out. The culmination of this work resulted in the first field demonstration of a mobile host wireless sensor network. The field demonstration took place on an out-of-service, full-scale bridge near Truth-or-Consequences, New Mexico.

A wireless sensor mesh network for health monitoring of structures is presented. It is a low cost, easy to deploy, fast and reliable wireless sensor network. Wireless nodes are all identical to each other with on board sensors for measuring acceleration and temperature. The acceleration data from the nodes used to detect the strain of the structure was calibrated using a Vishay P3 strain gauge instrument. These sensor nodes can collect data as well as relay the data of the neighboring nodes. Data from all the nodes reaches the base station through multiple hop relays. The nodes were tested for their performance by using different frequency channels and radio output power levels. This network implements an energy efficient routing protocol which can also handle a node failure in route without losing data. Different power conservation techniques were discussed which can keep the network unattended for a week after being deployed on the structure.
