Cable-Stayed Bridge Seminar and Design Guidelines This one-day seminar is intended to provide participants with an introduction to planning, design, and construction of long-span, cablestayed bridges. The seminar provides an overview of the features of cable-stayed bridges; their construction and maintenance considerations; and analyses needed to design these highly redundant structures including special aerodynamic studies. Major topics covered include: bridge configurations, construction methodology, component details, analysis, aerodynamics, design methodology, construction engineering, and maintenance and inspection. As part of the seminar, participants receive a copy of FHWA Design Guidelines for the Arch and Cable-Supported Signature Bridges. During the seminar, participants will become familiar with the features of cablestayed bridges. They will also better understand construction and maintenance considerations, as well as analyses needed to design and construct cable-stayed bridges. This seminar can be scheduled through the NHI. LRFD for Highway Bridge Superstructures Manual and Training This course is a combination of instructor-led discussions and interactive exercises, and includes a comprehensive reference manual. It includes load and resistance factor design (LRFD) theory applied to design examples and illustrates step-by-step LRFD design procedures. Exercises and example problems are based on components o f overall comprehensive bridge design examples using AASHTO LRFD. This course explains the background and methodology of the LRFD design and promotes proper application of code provisions. An update to this course to incorporate the 7th Edition of the AASHTO LRFD Bridge Design Specification is in the final stages. The estimated release date for this instructorled training and reference manual is July 2015. This training can be scheduled through the NHI. FUTURE ACTIVITIES FHWA has many projects underway intended to develop additional guidance, manuals, and training on bridge engineering. These projects include the topics of: refined analysis of bridge structures, design of post-tensioned box-girder bridges, advanced topics in precast concrete element design, system reliability in bridge systems, enhanced PT systems, bridge strengthening, and bridge durability design. A list of the expected soon-to-be-completed manuals and training are listed below: • Post-Tensioned Bridge Design manual • Manual on Refined Analysis of Bridges • Engineering for Stability in Bridge Construction • LRFD for Highway Bridge Superstructures Web-based Training More Information Courses listed below can be found on the National Highway Institute’s (NHI’s) website https://www.nhi.fhwa.dot.gov/default.aspx. Post-Tensioning Tendon Installation and Grouting Manual and Training Course No. 1301103 is expected to be available through the NHI in May 2015. The document can be viewed/downloaded electronically from http://www.fhwa.dot.gov/bridge/construction/pubs/hif13026.pdf. Post-Tensioning Tendon Inspection Training Module This lesson is part of the Bridge Inspection Refresher Training course (No. 130053A) and can be scheduled through the NHI. LRFD Seismic Analysis and Design of Bridges Reference Manual and Training There is complementary, instructor-led training (Course No. 130093) that can be scheduled through the NHI. The document can be viewed/downloaded electronically at http://www.fhwa.dot.gov/bridge/seismic/nhi130093.pdf. Cable-Stayed Bridge Seminar and Design Guidelines This seminar (Course No. 130096) can be scheduled through the NHI. All seminar participants receive a copy of FHWA Design Guidelines for the Arch and Cable-Supported Signature Bridges. LRFD for Highway Bridge Superstructures Manual and Training Course No. 130081 is expected to be available through the NHI in July 2015.
