Load & Resistance Factor Design Methodology for Bridges

California agencies are required to adopt the AASHTO load-and-resistance factor design (LRFD) specifications plus the California Amendments for design of all new bridges.

This 2-day course provides practical training to bridge design engineers and technicians on the application of the AASHTO LRFD specifications plus the California Amendments to the design of concrete bridges that are common in California (cast-in-place box girder, slab, precast, and box culvert bridges). All structural components of bridges are covered; but retaining walls and the geotechnical design of deep foundations are not.

This course emphasizes various technical design aspects of the LRFD bridge design specifications plus the California Amendments, which demonstrate how a uniform level of safety for bridges can be achieved.

This course is a hands-on training that combines lectures, class exercises on real-world bridge design problems, class discussions, and Q&A. Various bridge design examples utilizing the new LRFD specifications plus California Amendments are highlighted throughout the training.

Additional course detail is provided in the sections below.

  • What you will learn

    By the end of this course, students will have a broad understanding of the design methodology for bridges commonly constructed in California. They will gain practical knowledge of the application of the LRFD specifications with California Amendments to the design of bridges.

  • Who should attend

    This course is designed for bridge engineers and technicians from California agencies and the private sector, who wish to understand how the LRFD specifications achieve a uniform and accepted level of bridge safety, and how to appropriately use the LRFD specifications with California Amendments for bridge design.

  • Course Prerequisites

      Students should bring a calculator and pencil for in class problems.

  • Course Instructors

      Jay Holombo, PhD, PE, Principal Engineer, T.Y. Lin International

      Mr. Holombo has over 30 years of bridge engineering experience in California. He has worked for both Caltrans and private consulting firms performing bridge structural design, project management, and applied research. Mr. Holombo is a recognized leader in the development of seismic resistant precast/prestressed concrete bridge design.

      He has authored and co-authored numerous articles including the LRFD Minimum Flexural Reinforcement (NCHRP w147) that was recently adopted into the AASHTO LRFD Bridge Design Specifications. His teaching experience includes lecturing bridge design and to students and practicing engineers throughout California.

      Sami Megally, PhD, PE, SE, Principal Engineer, Kleinfelder

      Dr. Megally has over 29 years of research and analysis/design experience in reinforced and prestressed concrete structures. He is an expert in the field of seismic performance and serviceability of bridges and other structures, and served as a voting member of the ACI Committee 421 (Reinforced Concrete Slabs) and the ASBI (American Segmental Bridge Institute) Construction Practices Committee.

      Dr. Megally has also been the researcher/project manager for several research projects including monitoring of long-term deformations of the Confederation Bridge in Canada and seismic research projects for Caltrans. Dr. Megally has been project engineer on many bridge design and analysis projects, including segmental bridges, cable-stayed bridges and a suspension bridge.
