Evaluation of Bridge Condition for Safety and Bridge Rehabilitation

Course Outline

After participating in the course, you will be able to:
€¢ develop a better understanding of the application of 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.  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.
€¢ gain additional exposure to the state-of-the-art and innovative techniques for bridge rehabilitation and strengthening using fibre reinforced polymer sheets or rebars
€¢ boost your technical library with numerical examples for bridge evaluation 

Description As our transportation infrastructure ages, there is an increasing need on the part of owners to demonstrate greater duty of care.  One of the implications of this is the requirement for more thorough evaluation of structure integrity.
In many cases, the evaluation of existing bridge conditions and safety is done by visual inspection.  However, many defects are not evident either because they are physically concealed, as in underground components, or lie beneath surfaces as in corrosion damage.  As well, once located, the impact of these defects on safe load carrying capacity is difficult to determine.  Selecting appropriate and cost-effective rehabilitation measures is often hampered by limited information on the structural defects.
 
In this two day seminar, you will gain a strong working knowledge of the techniques that are applicable to the evaluation of bridges, including steel, concrete, and timber structures, with attention to load carrying capacity.  You will be better able to select the right load test for bridge evaluation, and to interpret the results produced.

The seminar will mainly cover the interpretation of Chapter 14 €oeEvaluation€ of the 2006 Canadian Highway Bridge Design Code (CHBDC), and related topics in Chapter 3 €oeLoads€ and Chapter 5 €oeMethod of Analysis€. Bending and shear strength of bridge girders rehabilitated or strengthened using Fiber reinforced polymer (FRP) sheets or bars will be presented in the second day of the seminar based on CHBDC provisions stated in Chapter 16. Solved examples for bridge evaluation will be presented for concrete and steel.

Objective

To provide the knowledge required to determine, what tests should be used what information regarding bridge conditions can be obtained from them, and how the evaluation information should be interpreted.

Who Should Attend

Engineers, technicians, technologists and managers with responsibility for bridge inspection, safety, design, rehabilitation or management; consultants in small and medium sized companies wishing to bid bridge inspection jobs; engineers in those organizations owning bridges who need to know what testing strategies best apply. 
                                                                                                                                                  

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. The emphasis will be on how to use these techniques in a bridge safety evaluation program, rather than the details of how each instrument or evaluation method works. 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.
