Upul Attanayake, Ph.D., P.E., Western Michigan University
Finite element (FE) is commonly used in bridge engineering for bridge component load demand for design or rating purposes. FE analysis is also used for construction process simulation, evaluation of bridge structural system behavior, or bridge diagnostics. From this educational presentation, the audience will gain an insight into basics of finite elements, FE selection process and their applications in bridge engineering while ensuring the quality of analysis.
Gregor Wollmann, Ph.D., P.E., HNTB Corporation
This pedestrian bridge comprises twin network tied arches with spans of 270 ft. A network of inclined hangers crossing each other offers significant advantages in terms of stiffness, reduction in materials and resiliency under extreme loading when compared to traditional tied arches with vertical hangers. The presentation will provide an overview of the history of network tied arches, explain the advantages of this system and will illustrate design and nonlinear effects during construction by example of this project.
Hilliard C. Bond, P.E., Parsons
This bridge, as part of the $500 million, 8-mile long I-580 Freeway Extension project in Reno, presented unique and challenging construction issues. The twin structures carrying six lanes of traffic span over 525m post-tensioned dual cell concrete box girders supported on 210m long arched piers. The audience will be exposed to such issues as geometry control and cambering, construction sequencing and casting variations, false work interaction above the arch, post-tensioning of multiple long tendons, and analytical erection engineering, which will become valuable reference for similar projects.
Antonio Ledesma, P.E., Parsons Brinckerhoff
For both I-95/I-295 North Interchange project in Jacksonville and the I-4/Lee Roy Selmon Expressway Interchange project in Tampa, the presentation will discuss the issues related to design and construction of the precast segmental flyover bridges. Both bridges are constructed using the balanced cantilever method of construction. The audience will gain an understanding of the design of a precast segmental bridge using the balanced cantilever method of construction and the analysis tools required to conduct the analysis.
