Workshops

W08: Introduction to Steel Bridge Fatigue and Fracture Design and Evaluation

Time: 8:00 AM – 12:00 Noon
Room: Annapolis 1

Presented By: Michael Baker International

This workshop will provide background on the development of the AASHTO LRFD provisions for fatigue design, evaluation, and, fracture control. The workshop will discuss the development and background of the specifications and provide a practical demonstration of the application of the LRFD design and MBE fatigue evaluation procedures for steel bridges. Opportunities to ask questions will be provided throughout. Participants are encouraged to discuss prior and ongoing steel bridge fatigue and fracture concerns and receive feedback from the instructors during the class. The technical content is based on selected material from the newly developed FHWA/NHI Course on Fatigue and Fracture.

Speakers: Dr. Francesco Russo, Michael Baker International, Philadelphia, PA; Brian Kozy, Ph.D., P.E., FHWA, Washington, DC

W09: Closer to Reality – Complex Bridge Analysis Software (Load Rating for Cable-Stayed Bridges)

Time: 8:00 – 10:00 AM
Room: Annapolis 2

Presented By: FINLEY Engineering Group

This presentation will discuss bridge load-rating analysis and modeling software specifically directed to cable-stayed bridges. The discussion will cover LFRF/manual of bridge evaluation specifications for load resistance factor rating as applied to cable-stayed bridges. The presentation will include details demonstrating how complex modeling is used and how appropriate rating equations are used to meet the intent of the rating philosophies as appropriate cable-stayed bridges.

This presentation will discuss how to use bridge analysis software for complex bridges including projects such as the Veterans Memorial Bridge where 3-D complex geometry, time dependent material properties, staged construction changing boundary conditions, composite section analysis, member activation/deactivation are described and demonstrated using a complex bridge project example.

Speakers: Jerry Pfuntner, P.E., S.E. and Ivan Liu, P.E., FINLEY Engineering Group, Tallahassee, FL

W10: An Overview of the Bridges to Prosperity Program – Planning, Design and Construction of Footbridges in Remote Rural Areas

Time: 8:00 – 11:00 AM
Room: Annapolis 3

Presented By: Michael Baker International

The objective of this workshop will be to give a comprehensive perspective of the planning, design, and construction undertaken on a typical Bridges to Prosperity footbridge project. The workshop will cover the perspective of the non-profit agency (Bridges to Prosperity) and discuss their overall program mission, goals, and plans for the future. In addition, the workshop will describe the logistics and effort required to establish a program in a foreign country that results in a program that constructs multiple bridges in one area or country. It will also give a perspective from a partnering consulting firm (Michael Baker Intl) who recently assisted B2P with a footbridge project in Nicaragua. The overall objective of the workshop will be to educate those who plan to participate in a future B2P project on the specifics of how the projects are undertaken and give insights on what to expect and prepare for on a typical project. An additional objective will be to generate more interest and enthusiasm for this exemplary organization’s humanitarian efforts and assist with the ongoing growth of their program.

Speakers: John Dietrick, Michael Baker International, Cleveland, OH.

W11: Implementing Bridge Asset Management Systems

Time: 8:00 – 11:00 AM
Room: Annapolis 4

Presented By: AECOM

The workshop will in summary review:

  • Alternative approaches to bridge asset management strategic planning. Examples of “big plan” and “small plan” and other alternative bridge asset strategic planning approaches will be discussed and exampled.
  • Currently available bridge management systems. Best practices, evaluation criteria and current field examples will be exampled and reviewed.

Opportunity will be provided for participant review, input and discussion.

Speakers: Simon Lewis, AECOM, Philadelphia, PA

W12: ABC Systems – Concrete Filled Steel Tubes for Bridge Applications-Seismic

Time: 8:00 AM – 12:00 Noon
Room: Baltimore 3/4

Presented By: WSDOT

This workshop will introduce new ABC technology and advancements to the bridge industry by industry leaders:

  • Easily constructible connections are an ABC challenge in seismic regions. WSDOT has developed a substructure design that incorporates Shape Memory Alloy (SMA) and Engineered Cementitious Concrete (ECC) in plastic hinging regions.
  • Accelbridge is a low cost, durable, and quicker to build full depth precast deck system than current methods. Attendees can learn more about engineering principles, and design and construction considerations, and experience from completed construction projects.
  • Premanufactured steel bridges and Buried Bridges offer many ABC advantages in terms of design time, material lead times, construction schedule & labor requirements, cost, and quality for low to medium span bridges. Applications and advantages will be demonstrated through a series of case studies.

Speakers: Bijan Khaleghi, WSDOT, Tumwater, WA; Eddie He, AccelBridge; Joel Hahm, PE, Senior Engineer; Sean Johnson, PE, Engineering Manager, Big R Bridge, Greeley, CO

W13: Engineering Ethics

Time: 11:00 AM – 12:00 Noon
Room: Annapolis 2

Presented By: AECOM

Engineering ethics is a system of moral principles that sets the obligations of engineers to society, to their clients, and to the profession. It has a basis in the philosophy of science, the philosophy of engineering, and the ethics of technology. Because engineering impacts the quality of life for all people, engineers must perform under a standard of professional behavior that requires adherence to principles of conduct described by established codes of ethics. This session will review the development of engineering codes of ethics with a focus on general principles, obligations to society, responsibilities, whistleblowing, and conduct. It will then demonstrate these concepts through an examination of several case studies.

Speakers: Elliott Mandel, P.E.,Senior Project Manager, AECOM, Alrington, VA; Lusanna Ro, Esq., Vice President, Chief Counsel, DC Metro and Southeast Region, AECOM, Glen Allen, VA
