A Review of Some Notable Bridge Problems and the Role of Quality Control
The role of quality control in the problems that occurred in 3 major bridges will be presented. Often quality control of bridge structures is solely concerned with the quality of the contractors building the bridge. Quality control in the design office is also critical should not be overlooked. In addition, the designer needs to heed the warnings in the specifications when specifying products. A note on the plans while clearly written is also no guarantee of quality if they are not enforced during fabrication. A tale of 3 bridges illustrating the importance of the control quality from design, material selection, and through to fabrication.

Kosciuszko Bridge
Everyone knew there would be nothing easy about replacing New York City’s Kosciuszko Bridge. The team that accepted the challenge would have to relocate decades of underground uti lities, resolve major drainage issues, work within extremely limited right of way, avoid an active hazardous waste site and fulfill theenormous task of keeping the existing bridge open to traffic.

Understanding Public-Private Partnerships – The Impact on Bridge Design
Alternative project delivery is becoming increasingly popular among our public-sector clients.  In pursuing projects using alternative project design, including Public-Private Partnerships (P3) and Design-Build (DB), it is important to understand what a P3 is, how it works, and how it differs from a design-bid-build project.  Goals and expectations may differ greatly from what you normally experience when working on a project for a public agency.  This presentation will cover those topics to provide the bridge designer with a greater understanding of P3s and how it may affect them.

Driving a Bridge down the Expressway: Australian-first bridge move using Self-Propelled Modular Transporters
The Darlington Upgrade project is a $620 million project to improve one of the most important transit corridors in Adelaide, Australia. Jacobs’ Chicago office was responsible for the analysis and design of a continuous, three-span, curved steel tub-girder bridge over a major expressway. To minimize closures on the expressway, the contractor chose to build the superstructure in its entirety at an offsite location and move the bridge into place using self-propelled modular transporters (SPMT’s). The move was facilitated by closing the expressway over a long weekend and “driving” the bridge to the final location. The continuous spans combined with a flexible superstructure made the structure susceptible to a large combination of undesirable displacements during the move. The focus of the presentation will be on the design effort and planning that was devoted for the analysis of the SPMT move. Additionally, bridge monitoring techniques and lessons learned will be presented.

Barry is a Professional and Chartered Engineer, and a Fellow of the Institution of Civil Engineers in London.

Good Practice in the Management of Long Span Suspension Bridges
This presentation will look at current good practice and show the latest developments in the inspection, maintenance, preservation and rehabilitation of long span suspension bridges. Current projects describing main cable and anchorage dehumidification will be covered as will projects where particular key elements have been replaced such as decks, suspenders, and cable band bolts.

The presentation will also look at a developing method of using a risk based methodology on complex bridges to set inspection frequencies and prioritize capital programing. This methodology is currently being used for the first time in the US.


Zachary Taylor specializes in aerodynamics and structural vibration as an associate at RWDI. He holds a B.E.Sc. in mechanical engineering and a Ph.D. in civil engineering each from the University of Western Ontario. The focus of his research and professional work has centered on bridge aerodynamics and structural dynamics. Since joining RWDI, he has helped to develop analytical capabilities for wind-, vehicle- and pedestrian-induced vibrations of flexible structures. He works closely with many of the leading bridge design firms to perform wind tunnel testing, numerical vibration analyses and full scale testing of landmark bridges around the world.

Simulation and Mitigation of Pedestrian-Induced Vibrations on the Hunt Club Bridge
Pedestrian bridges are often architecturally unique and structurally-efficient designs. Thus, many of these bridges are light, relatively flexible, and susceptible to dynamic forcing. The two most significant sources of dynamic forcing for pedestrian bridges are wind and the pedestrians themselves. RWDI served as the wind-induced and pedestrian-induced vibration consultant for the Hunt Club Pedestrian Bridge in Ottawa, Ontario, Canada. The presentation will focus on the pedestrian-induced vibrations of the bridge, including prediction of the pedestrian loading, simulation of the bridge response and the design/installation of the mitigation measures to control the response of the bridge.

 


Tony Shkurti, Ph.D., SE, PE, serves as a Great Lakes bridge lead engineer and Associate Vice President in HNTB and is a nationally recognized authority in structural engineering. His research includes seismic retrofit of bridge substructures, redundancy of bridge superstructures, bracing systems, fatigue and fracture behavior of steel bridges, infrastructure security risk assessment and mitigation and vehicular impact analysis. He has presented and published in numerous venues.

Nonlinear Analyses of Four Existing Steel Bridges with Integral Steel Pier Caps for Investigating and Providing System Redundancy
HNTB has contracted with MN DOT to determine whether four bridges in Duluth MN are truly fracture critical as currently designated or whether system redundancy can be demonstrated through sophisticated non-linear analyses and the application of criteria established in NCHRP Report 406. The investigation of redundancy includes developing detailed FEM models and member capacities upon which to compare demand. In locations where system redundancy is determined to not be present through alternate load paths, repairs to provide system or member redundancy are developed to reduce the risk of fracture critical failure. While addressing redundancy, the project aims to also extend the bridge service life through painting and repair recommendations. Details of the bridges, the redundancy evaluation through the application of linear and non-linear FEM using Larsa4D as the prime modeling tool, as well as CSI Bridge fully independent analyses, and structural recommendations are included.

Four Key Considerations When Working on Bascule Bridges
While bascule bridges represent a small fraction of the bridge inventory in the United States, their maintenance and operation needs far exceed those of fixed bridges. Consequently, designers and contractors who perform work on bascule bridges must consider the unique and complex structural engineering challenges associated with their inspection, evaluation, rehabilitation, and performance. The presentation will delve into these four key considerations, each one with case study examples from Chicago-area IDOT and CDOT bascule bridges. The case studies will be used to illustrate the complexities and possible solutions when working on bascule bridges.
