October 24, 2019 - 8:00am to 5:00pm

The Structural Engineers Association of Illinois is pleased to announce the Ninth Annual Structures Symposium, which provides a forum for engineers to share analysis, design, and construction information from recent projects with unique and/or distinguishing characteristics.  Attendance typically represents a diverse cross-section of all aspects of the profession, including design, construction management, material suppliers, academia, general contracting, and owners’ representatives. 

Keynote Speaker

Robert Forest, FAIA, RIBA, LEED AP Partner, Adrian Smith + Gordon Gill Architecture

Stand Up

In the presentation, Bob will address the role of structure in performance-based design by considering the relationships between Form and Performance through an integrated design process that includes building performance and embodied carbon.

Bob, AS+GG’s Management Partner, is dedicated to advancement management within an architectural context. He has extensive experience in the execution of complex, large-scale projects on an international level. Bob’s expertise in project management and technical architecture contribute to his comprehensive understanding of the built environment and the practice of architecture. Bob pushes the boundary of Adrian Smith + Gordon Gill Architecture’s performative architecture philosophy: ‘Form follows performance’ through every aspect of the practice. As a recognized authority on the economics of sustainable design, Bob has combined his knowledge of local and international policies, funding sources, and varied economic models into a comprehensive system of best practice. Bob played professional football for the Ottawa Rough Riders and Montreal Machine and he utilizes the leadership skills and understanding of team dynamics gained from this experience today in a professional capacity.

Attendees receive 7.0 hours of continuing education credit for the Symposium.

Al Wasl Plaza Trellis of Dubai Expo 2020

The Al Wasl Plaza, which serves as the centerpiece of the World Expo 2020 in Dubai is anchored by a grand spherical structural steel gridshell 70 meters in height and 135 meters in diameter at the base. Unlike traditional diagonalized gridshells, the unique structural framework of the “Trellis” draws its inspiration directly from the iconographic logo of Expo 2020 Dubai as a series of nested and tangent rings that result in a flexurally governed ductile structural system. Key structural engineering considerations related to the geometric definition, loading and performance criteria, global stability and imperfections, steel fabrication, and erection are outlined.

High-Performing Lintels for Masonry Walls

This presentation illustrates the actual behavior and load distribution of a lintel within a wall, to help us understand how to design this common element more effectively.  We will lay the groundwork for lintel design including the basics of arch analysis, design criteria, and the various options we have in selecting lintels in masonry walls.  It will outline specific assumptions that impact masonry walls and lintels, such as masonry strength and control joint locations.  We will explore how the design of masonry lintels can add significant structural and architectural benefit to the wall that contractors and owners will welcome for crack and corrosion prevention.  This presentation focuses on sharing practical design tips leveraging software analysis tools and having a more in-depth understanding of the behavior of this commonly-used structural element. 

This session will also highlight design approaches to structural clay (brick) masonry design.  We will lay the groundwork for understanding material properties of structural clay masonry, and contrast behavior between concrete and clay masonry.  Innovative solutions to achieving structural brick veneer walls without the use of backup walls will also be explored.

R. Tyler Ranf, Ph.D., P.E., S.E.

Senior Associate - Magnusson Klemencic Associates

Enabling the Vision of the Nashville International Airport

Nashville International Airport’s Terminal Lobby and International Arrivals Facility Addition presented many design challenges due the various existing structures, available footprint, functional and aesthetic design goals, cost, and construction phasing to maintain operation and passenger comfort throughout construction. This presentation will focus on how these challenges informed the structural design, and how they shaped the final unique, function- driven design while meeting the aesthetic and operational goals of our team and the airport.

EMARR Skyview – The Design and Construction Challenges of Linking Two Towers with a Bridge

Located in Dubai, UAE, EMARR Skyview opened in May 2019. Occupying a prominent site close to the Burj Khalifa, the program of the towers consists of providing residential/ hotel usage with views of Burj Khalifa, with the connecting bridge serving as an event space/infinity pool from which to view the world’s tallest building. Tower 1 is 58 stories tall and houses serviced apartments; Tower 2 is 54 stories tall and houses serviced apartments and an hotel. The towers are linked together at Level 48 by a multi-story bridge structure, spanning approximately 90m. Images of the project can be found at the following link:  https://www.emaar.com/en/what-we-do/communities/uae/downtown-dubai/the-address-residence-sky-view.aspx

Refined Analysis of Steel Platforms Subjected to Thermal Loads at an Industrial Facility Containing Hazardous Materials

An industrial facility containing hazardous materials was at risk of shutdown after discovering a previously-unanalyzed condition in which steel personnel access platforms subjected to high temperatures following the rupture of a large, high-pressure steam line could collapse and damage essential systems and components below. Such a shutdown and subsequent repairs would be very costly to both station personnel (in terms of exposure to hazardous materials within the facility) and lost revenue generation at the facility (over $2 million per day that the facility is shutdown). A team from Jensen Hughes, using refined finite element modeling techniques, was able to demonstrate that the platforms would maintain their structure integrity after such an event, thus allowing the facility to remain in operation.

95th Street Terminal Improvement

The 95th Street Terminal underwent the largest reconstruction in CTA history in order to improve the overall transit experience and create an iconic gateway design at the southern entrance to the City of Chicago. The scope included renovation and expansion of the existing North Terminal, construction of a new South Terminal, new and expanded pedestrian and roadway bridges, while meeting a number of unique site and operational constraints. Re-use of the existing North Terminal led to a number of challenges, such as the removal and relocation of numerous columns at the first-floor level.
