• Title: Bridging Big Data Project Results and the Path Forward
• Abstract:

  This presentation will discuss findings from past workshops, collaborative efforts to prepare prototype platforms and the path going forward. We will discuss the interconnected elements of a SMArt big data pipeline for Aging Rural bridge Transportation Infrastructure (SMARTI). Each SMARTI focus area will investigate specific challenges and solutions through data collection efforts from a representative set of rural bridges in the Midwest. This presentation will also highlight specific capabilities of project participants and collaborators.

10:30 to 11:45 p.m.

• Title: Framework for Risk-Based Inspection Practices
• Abstract:

  This presentation will discuss a new risk-based methodology for determining bridge inspection intervals and procedures. The methodology is a rational, reliability-based method that has the goals of ensuring bridge safety and serviceability, and ensuring effective asset management. Currently, inspection intervals are calendar-based and require routine inspections at a maximum interval of 24 months. This uniform calendar-based approach results in the same inspection interval for new bridges as for aging and deteriorated bridges. The RBI methodology consists of a bridge owner performing a risk assessment of bridges to identify those bridges that are most in need of inspection to ensure bridge safety, and those where inspection needs are less. This assessment identifies likely damage modes and deterioration mechanisms affecting the condition of bridges, and projects future damage based on systematic expert judgement. Deterioration models and data from health monitoring technologies can also be used to assess the likelihood of future damage. Consequences are assessed in terms of safety and serviceability of a bridge; a simple risk matrix is used to identify the appropriate inspection interval based on the risk assessment. In the way, asset management can be improved by focusing inspection resources where most needed, and reducing unnecessary inspections. The RBI approach represents a new paradigm for bridge inspection that may transform traditional calendar-based inspection approaches, improving the allocation of resources while ensuring that safety and reliability of the highway bridge infrastructure.

• Theme: Next-Gen Health Monitoring
• Moderators: Richard L. Wood and Raj Dasgupta.

Talk 1

• Title: Using Unmanned Aerial Systems (UAS) with Lasers to Assess Structural Performance
• Abstract:

  Recent advances in drone technologies present potential opportunities to enhance and/or increase the safety of conducting visual bridge inspections, as well as provide for accuracy and efficiency in Structural Health Monitoring (SHM) and in monitoring safe rail operations. This presentation will describe using vibrometers carried by unmanned aerial systems (UAS) to collect bridge displacement data in real time. A product of this research is a proven method to collect displacements in the field without a reference, which was not available before. The close collaboration with railroads will permit researchers to prove that this technology can be used in the field during railroad operations.

• Speaker: Fernando Moreu Alonso, Department of Civil Engineering at the University of New Mexico (UNM) at Albuquerque, NM. Cross-appointed in the Department of Electrical and Computer Engineering.

Talk 2

• Title: Robotic Inspection for Infrastructure Facilities and Nuclear Sites
• Abstract:

  In this talk, the set of perception, planning and control methods that aim to enable comprehensive, systematic and repeatable robotic inspection of infrastructure facilities and nuclear sites are presented. Either with or without any prior model of the environment, possibly in GPS-denied or even visually-degraded conditions, the proposed methods enable robust autonomy for small aerial robotics. Beyond the algorithmic contributions, a set of field experiments will be presented alongside associated open source code and datasets.

• Speaker: Kostas Alexis, Computer Science & Engineering Department, University of Nevada, Reno.
