W-8: Service Life Design – Worked Design Example

Time: 8:00 a.m. – 12:00 Noon
Room: Baltimore 3

Service Life Design is still an emerging technology in the US. The SHRP2 R19A project aims to assist public agencies with the implementation of service life design on bridge projects. Engineers participating in the SHRP2 R19A project have indicated a desire to see the step-by-step process of performing a service life design. This workshop will identify the process for a concrete bridge project in a chloride environment. The workshop will be split into multiple focused modules all centered around the example bridge project. Specific presentations will include how to identify and use existing codes and standards for service life design, determine environmental loading parameters, select different design methodologies (deemed-to-satisfy, avoidance of deterioration, full-probabilistic deterioration modeling, partial factor method), perform mathematical deterioration modeling to select concrete durability resistance properties and required cover, specify concrete and reinforcing steel durability resistance, identify specialized material tests required, and how to document the process.

W-9: Future of Bridge Management: Program Modeling, Inspections, Design & Delivery

Time: 8:00 a.m. – 12:00 Noon
Room: Baltimore 4

Demonstrating BIM for Bridges – Moving to Digital Delivery

The object of the workshop will be to disseminate information on digital bridge design delivery; data exchange platforms and standards for data delivery from design software to construction and fabrication, and highlight DOT case study and demonstration projects in Bridge Information Modeling (BIM/BrIM). Feedback from the participants will also be solicited specifically to help develop standard contract language to facilitate digital delivery, as well hear feedback on the ease of use of the data exchange platforms and how they can be developed to benefit bridge owners.

Presenter: Kelley Severns, WSP USA, Old Hickory, TN; Joe Brenner, P.E., WSP USA, Ephrata, PA

Technology Applications (software and drones) for bridge 3D modeling, design, construction and inspection

Present the software and hardware (drones) solutions available at Bentley Systems for 3D bridge modeling, design, construction and inspection.

Digital Fast Track: Parametric Modeling of Automated People Mover Rail Structure

Digital tools are increasingly allowing structural engineers to develop efficient workflows to design and model structural elements. These digital workflows were instrumental in the planning and delivery for the design of a 3-mile long automated people-mover rail structure. Due to the scope of the project and its construction above an existing and active major airport, coordination with roadways, buildings, utilities, and airport operations posed a significant challenge. Therefore, it was of paramount importance to make BIM and analysis models sufficiently agile to address alignment and structural changes rapidly as the design team and airport evaluated different solutions. Using a variety of different software packages, the structural team parametrically modeled the miles of track and resulting structural geometry based on allowable column locations and the current railway alignment profile. This allowed for quick turnaround after design changes and rapid quantity take-off and cost estimation information to assist the client in the decision-making process. This presentation will demonstrate to attendees the value and efficiency of parametric modeling, which will be crucial to the future of the industry.

W-10: Design of Steel Bridges for Railways

Time: 8:00 a.m. – 12:00 Noon
Room: Baltimore 5

The workshop will introduce attendees to the history and development of steel railroad bridges, discuss modern railway design loads, demonstrate the different aspects of steel bridge analysis for railroad bridges, and address the design of various members and connections. It will cover a portion of the topics presented in Design and Construction of Modern Steel Railway Bridges by John Unsworth. The main objective of the workshop will be for attendees to develop an understanding of American Railway Engineering and Maintenance-of-Way Association (AREMA) Design Guide Chapter 15 for Steel Structures and learn how to apply it.
