TRAINING.

Overview

After participating in this course, you will be able to:

• Confidently apply the Canadian Highway Bridge Design Code to various bridge rehabilitation projects.
• Utilize advanced techniques and innovative approaches to repair and strengthen bridge structures.
• Conduct thorough assessments of bridge conditions using both non-destructive and destructive testing methods.
• Develop effective rehabilitation strategies for concrete, steel, and composite bridge superstructures.
• Incorporate Fiber-Reinforced Polymer (FRP) composites and other modern materials into bridge rehabilitation practices.

Description
Understanding the complexities of bridge rehabilitation is essential for maintaining the safety and functionality of transportation infrastructure. Over time, bridges can deteriorate due to environmental effects, design deficiencies, or increased vehicular loads. This course delves into the typical damage patterns in bridge structures and explores the comprehensive assessment techniques necessary for evaluating these issues, including visual inspections and various testing methods.

Participants will gain hands-on knowledge of the Canadian Highway Bridge Design Code and learn state-of-the-art rehabilitation techniques. The course covers the use of specialized equipment for bridge inspection and condition survey procedures. Key topics include rehabilitating concrete and composite bridge superstructures and applying FRP composites in structural repairs. Attendees will understand how to apply these techniques by exploring real-world examples and case studies.

By the end of this course, you will be equipped with the skills needed to effectively assess and address structural deficiencies in bridges. Whether dealing with concrete, steel, or composite materials, you will learn how to enhance the durability and safety of bridge structures using modern rehabilitation methods.

Who Should Attend
This course is designed for bridge rehabilitation engineers, structural designers, and inspectors responsible for maintaining and improving bridge structures. Managers and consulting engineers involved in bridge projects will also benefit from the advanced knowledge of assessment and rehabilitation techniques provided.

Superintendents, contractors, fabricators, material suppliers, and material testing personnel will find the practical insights invaluable for their roles. Additionally, regulatory agency staff involved in infrastructure oversight will better understand bridge evaluation and rehabilitation standards. This course is ideal for anyone involved in assessing, repairing, or strengthening bridge infrastructure.
