Abstract:

The Gordie Howe International Bridge demonstrates how latex-modified concrete (LMC) is redefining infrastructure durability in North America. Connecting Detroit, MI, USA, and Windsor, ON, Canada, across the Detroit River, this engineering achievement features a cable-stayed design with a main span stretching approximately 2800 ft (900 m), flanked by side spans of roughly 1200 ft (400 m) on each end. The cable-stayed portion alone extends nearly 1 mile (1.6 km), making it the longest cable-stayed bridge in North America. The crossing is expected to facilitate billions of dollars in annual trade while alleviating congestion at one of the continent’s busiest international border points.

Abstract:

Built in 1964, the John Coffee Memorial Bridge is a two-lane, 38-span, plate-girder bridge with a concrete deck that provides a direct route for travelers from Tennessee to Mississippi. Because of its scale, inspection is challenging. A recent evaluation was conducted to select appropriate restoration methods, using robotic tools that enabled nondestructive evaluations (NDEs) without the need for traffic control. This article describes these tools and summarizes the evaluation.

Abstract:

During a Transportation Research Board (TRB) webinar, Roberto Piacentino, Precast Sub-Segment Manager for Geoquest, presented the TechSpan® System, a three-hinged precast arch system used to construct buried bridges. This article highlights a bridge built with the TechSpan System in Ras Al Khaimah, United Arab Emirates, in 2000.

Abstract:

Concrete bridges offer a combination of strength, durability, versatility, and sustainability that make them a preferred choice for many infrastructure projects. However, there are some unique differences between concrete building and bridge analysis and design. The following three concepts were identified by the authors as the most unique, and they are often associated with student confusion in a bridge analysis and design course: applied loads and limit states, shear capacity of prestressed concrete bridge girders, and bridge deck equivalent strip design. This paper presents an overview of the key concepts related to concrete bridge analysis and design that instructors can highlight. Furthermore, this paper includes significant resources that can be used when starting a bridge analysis and design course, including syllabus content, learning objectives, assessment tools and rubrics, available technical resources, and methods of integrating them into undergraduate and graduate level courses. Lastly, innovative teaching techniques are discussed that can aid in removing the difficulty often associated with teaching and learning about concrete bridges. The paper highlights lessons learned from the authors based on observations from several years of instruction.

Abstract:

Teaching college students advanced concrete materials and structural concrete design is a challenging task because students have a myriad learning styles, and instructors are often ill equipped to meet students where they are with appropriate experience and teaching-related resources. This disconnect can create several bottlenecks to learning, especially within courses that present advanced concrete topics that are more complex and challenging. This paper outlines a special publication series related to best practices and lessons learned for teaching advanced concrete materials and structural design by experts in the field from across the United States. Furthermore, this introductory paper outlines the history of teaching and learning resources at the American Concrete Institute (ACI) and provides a high-level overview of other technical concrete-focused resources and teaching development resources that can be used to bridge the gap between teaching and learning challenging concrete subjects. The goal of this special publication is to provide a resource for anyone that accepts the challenge of teaching advanced concrete materials and structural design, from a new instructor to an experienced professor.
