Precast concrete bridge components and systems provide effective and economical design solutions for new bridge construction and for the rehabilitation of existing bridges. The use of precast components can shorten road closure times, minimize interference with traffic flow, and accomplish the objective often cited by officials to “get in, get out, and stay out.”

This course is intended to augment, and not replace the AASHTO Guide Specifications for LRFD Seismic Bridge Design (AASHTO, 2009) (referred to herein as the LRFD Seismic Guide Specifications) or any agency requirements for seismic analysis or design. The designer should verify the latest applicable standards with the owner and discuss any necessary exceptions before beginning design.

For current state-of-the-practice, the seismic design of precast concrete bridges employs an AASHTO-LRFD Type 1 design strategy and uses connections between precast concrete elements and between cast-in-place (CIP) concrete and precast concrete elements that are intended to emulate the behavior of CIP concrete connections.

Learning Objectives

Upon completion of this course, participants will be able to:

• Identify potential causes of earthquake damage to bridges with precast components.
• Interpret seismic hazard maps.
• Explain seismic performance criteria for precast concrete bridge structures.
• Describe precast systems and components, including superstructure types and substructure components.
• Analyze the structural response of various precast bridge systems.
• Apply the seismic design criteria in the AASHTO specifications.
• Describe connection details used in precast bridges.
• Follow step-by-step design examples that include detailed calculations, checks, and screenshots of the software used.

Certificate of Completion
