Purpose and Background

Since the construction of modern structures, civil engineers have been assisting infrastructure owners with planning, designing, constructing, and inspection of their assets using the methodologies that have been developed empirically. Most of these heuristic approaches are based on simplified assumptions. As infrastructure, especially the bridge inventory, continues to age and becomes a more complicated system, its behavior changes. In these cases traditional methodologies provide a significant challenge to bridge engineers, especially during inspection, load rating, and overall safety assessment of aging infrastructure assets. Even though, in some cases, the current conventional approaches have met the needs of owners, there are an increasing number of situations where they have been proved insufficient. In recent years, engineers and bridge owners have started to (use or deploy or employ) smart technologies and sensing techniques to help with planning, evaluation, and monitoring of their assets.

This webinar explains and discusses the basics of new technologies and techniques being used in the assessment and evaluation of bridges. This course will also discuss and present a general overview of traditional and modern load rating and condition evaluation methods.

Course topics include the current state of transportation assets in the United States, traditional load rating methods, application of finite element modeling in load rating of bridges, instrumentation and load testing of bridges, other applications of sensing and simulation in assessing bridge structures such as structural health monitoring of existing bridges, and application of robotic systems, data analytics, and other autonomous or semi-autonomous technologies in bridge condition assessment.

How to Earn your CEUs/PDHs and Receive Your Certificate of Completion

To receive your certificate of completion, you will need to complete a short on-line post-test and receive a passing score of 70% or higher within 1 year of purchasing the course.

How do I convert CEUs to PDHs?

1.0 CEU = 10 PDHs [Example: 0.1 CEU = 1 PDH]
