CATALOG DESCRIPTION
Analysis and design methods for modern highway bridges. Slab, Slab-Stringer, Plate Girder, Box Girder bridges constructed from reinforced concrete, steel, prestressed concrete. Strength and Serviceability criteria. Bridge proportioning for optimum performance. Bridge aesthetics, inspection and rehabilitation.
OBJECTIVES
This course is designed to be an
introduction to the applied field of Bridge Design. Starting with the history
of bridge building and an overview of various types of bridges, the course
introduces the student to analysis and design of Slab, Slab-Stringer, T-Beam, Plate
Girder and Box Girder bridges. The course closes with a discussion of bridge
aesthetics.

RELATIONSHIP TO CURRICULUM SEQUENCE
This course, being applied in nature, is of most value to the student who has completed all necessary analysis and design prerequisites. A student working towards a graduate degree specializing in Structural Engineering could take this course. A student majoring in Transportation Engineering may also take this course to complement the planning-type courses.
This is a recommended course for students majoring in Structural Engineering. It provides training in the structural design of highway bridges to complement the architectural design concepts taught in other Transportation Engineering courses.
