Abstract

Wireless Smart Sensor (WSS) process field data and inform structural field engineers and owners about the infrastructure health, condition, and safety. Engineers acquire the data and investigate changes on displacements under loads to make informed choices and prioritize decisions concerning maintenance, required repairs, and infrastructure replacements. However, reliable data collection and access to displacement information in the field in real-time under loads remains a challenge. The displacement data provided by the WSS in the field undergoes additional processing, and it is seen at a different location, at the decision-making headquarters. If inspectors were able to observe structural displacements in real-time at the locations of interest, that would enable a new information-based decision-making reality in the field, and it would also make it possible for the inspector to conduct additional observations based on that information. As a solution, this thesis develops a new human-centered access to actionable structural data (real-time displacements under loads) using Augmented Reality (AR). The main contribution of this work is a real-time human-infrastructure interface that facilitates inspectors’ direct access to displacement data during the structural inspection and monitoring.
