Graduate course - Lecture format – 3 credits – Meets once a week on Tuesday from 6:00 to 9:05 pm
The course covers the bridge engineering process of short-span bridges from design to maintenance and rehabilitation with a special focus on steel and reinforced concrete bridges. The various major forms of short-span bridges are presented with an emphasis placed on the most prevalent types and on highway bridges. The structure of a bridge, its superstructure and substructure members and other related elements such as abutments, foundations and retaining walls are examined using a practical approach which includes some computer applications. Design procedures are covered based on the latest AASHTO requirements, and the ACI and ASCE standards for structural analysis and design.
§ Prerequisites/ Required Skills:
Prerequisites: undergraduate courses in steel design and concrete design, and some knowledge of prestressed concrete fundamentals. Design and performance of highway and railroad bridges, particularly steel and prestressed concrete structures since they are most common in the northeast; and computer applications including bridge geometry, abutment design and composite beam design.
Mathematical skills and computer skills are also expected.
