Course description
A considerable amount of research work on highway bridges has been carried out around the world over the past several decades, especially in North America. This let to the development of the first limit states bridge design code in Canada in 1979. Recently, a new Canadian Highway Bridge Design Code has been published which includes several advanced analysis and design methods as well as new construction materials, such as FRP. More and more countries have adopted the limit states design philosophy and Canadian code criteria for the design of their highway bridges.
The objectives of this course are three folded:
1) Introduction of the limit states design method;
2) Discussion of design philosophy and code requirements and
3) Examples of analysis and design of bridge super-structure components, using limit states design method.
This course will be focused on the bridge superstructure only. No attempt has been made to deal with the bridge substructure or foundation problems.
The course will mainly follow the current Canadian Highway Bridge Design code; although other codes such as AASHTO and British code will also be referenced. The course will cover the following major areas:
Review of limit states design method; legal loads and highway design loads; load combinations; concrete deck design; load distribution theory; refined methods of analysis; impact and dynamics; load capacity rating of existing bridges; computer analysis methods; fatigue and brittle fracture; construction bracings, etc.
