Structural Rehabilitation of Bridges

The course will be an excellent exposure of the Canadian Highway Bridge Design Code with respect to bridge evaluation, rehabilitation and the use of fiber-reinforced polymer (FRP) technology in bridge repair.

Course Outline

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

Apply the Canadian Highway Bridge Design Code in conducting step-by-step manual calculations for the evaluation of the bridge load carrying capacity in both flexure and shear, axial tension and compression.  This would assist bridge designers, owners to decide on keeping the bridge as is, posting the bridge, rehabilitating or strengthening the bridge, or demolishing it
Select the state-of-the-art and innovative techniques for bridge rehabilitation and strengthening.
Perform bridge evaluation and rehabilitation following the numerical examples you work on in the class  

Description

In Canada, the number of bridges requiring rehabilitation is increasing at an alarming rate.  Addressing this problem consumes an ever-growing percentage of government budgets.  Bridges need to be rehabilitated for a variety of causes, such as deterioration due to environmental effects, the need to carry heavier vehicular loads, or deficiencies in the original design or construction.  Those responsible for maintaining bridges need to keep abreast of the latest techniques available for assessing the condition of their structures, as well as the methods and techniques for repairing or strengthening them. At this seminar you focus on the technical aspects of bridge rehabilitation, such as the use of bridge inspection equipment, condition survey procedures, and the latest, practical methods of repairing and strengthening existing bridges.  You are also expected to case studies and design examples. The course will be an excellent exposure of the Canadian Highway Bridge Design Code with respect to bridge evaluation, rehabilitation and the use of fiber-reinforced polymer (FRP) technology in bridge repair.

Objective

To present practical and economical methods for evaluating, inspecting, strengthening and rehabilitating bridges.

Who Should Attend

The course suits primarily the bridge rehabilitation engineers, structural designers and inspectors. However, managers and engineers of national, provincial and local highway agencies, railway bridge engineers, consulting engineers, superintendents and contractors, fabricators, material suppliers and material testing personnel who are interested in rehabilitation of bridges, regulatory agency staff and others responsible for inspecting, maintaining, upgrading and safeguarding existing bridges.

Special Features
The speaker has been selected for his first-hand experience with bridge design, evaluation, rehabilitation and strengthening. You will have time to meet and share experiences with others in the field.  Presentations will stress practical applications. You will learn what information each technique produces and how to use this information to evaluate bridge safety and rehabilitation strategies.  While the course will discuss future developments of innovative FRP technologies, it will focus on practical applications for use now.
