Structural Expression in University Building Design: How Steel Framing and Glazing Systems Create Iconic Campus Architecture

The Architectural Vision Behind Expressive University Buildings

University buildings serve more than a functional purpose. They represent the identity, values, and aspirations of the institutions they house. When a university building design successfully expresses the mission of its occupants, it becomes a landmark that shapes campus culture for generations. The Mori Hosseini Student Union at Embry-Riddle Aeronautical University in Daytona Beach, Florida, stands as a powerful example of how expressive structural design can capture the essence of an institution. Designed by ikon.5 architects, the 177,000-square-foot student union building embodies the principles of flight through its soaring forms, exposed steel framework, and dramatic glass elements.

Educational buildings designed around a central architectural metaphor create stronger connections between the physical environment and the academic experience. For professional builders and contractors, understanding how to translate conceptual design goals into buildable structures is essential when working on university center construction standards that demand both aesthetic excellence and structural integrity.

This article examines the key architectural strategies used in the Embry-Riddle student union, providing practical insights for construction professionals working on expressive institutional projects.

Structural Steel as a Design Medium for Architectural Expression

Architecturally exposed structural steel (AESS) is one of the most effective tools for creating visually striking building forms. Unlike concealed steel that is hidden behind finishes, AESS becomes a primary visual element of the architectural design. The Embry-Riddle student union employs AESS extensively, turning structural necessity into aesthetic opportunity.

The Role of Exposed Steel in Conveying Movement

The building features a 200-foot curving steel arch that bisects the floor plan and supports a glass roof above. This single structural element accomplishes several design objectives at once:

• Creates an immediate visual connection to aviation themes through its aerodynamic curve
• Supports the skylight without requiring obstructive vertical columns
• Frames the interior space to draw the eye upward, reinforcing the flight metaphor
• Establishes a rhythmic structural language that continues throughout the building

The quality of fabrication and finish for exposed steel must meet higher standards than conventional structural steel. Weld seams must be ground smooth, bolt connections must follow consistent patterns, and protective coatings must be applied with attention to visual appearance as well as corrosion resistance. When specifying architecturally exposed structural steel specification requirements, contractors should clearly define surface preparation standards, weld quality expectations, and coating application methods in the project documents.

Vertical Struts and Feather-Like Structural Elements

Beyond the primary arch, the building uses vertical exposed struts that convey a feather-like quality. These structural members serve the dual purpose of tying down the curved roof form against wind uplift forces while contributing to the overall avian aesthetic. In Florida, where hurricane-force winds are a design consideration, these struts must meet rigorous structural performance criteria while maintaining their visual delicacy.

Key considerations for exposed strut systems in expressive building design include:

• Connection detailing that accommodates thermal expansion and contraction
• Wind load calculations that account for the aerodynamic shape of the roof
• Finish selection that balances visual appeal with long-term durability in coastal environments
• Coordination between structural engineering and architectural intent at every connection point

Glazing Systems and Skylight Design for Institutional Buildings

The glass elements of the Embry-Riddle student union are integral to the design concept. The 200-foot arching skylight that crowns the top-floor library allows students to look skyward, reinforcing the aviation theme while providing natural daylight to the interior spaces. Glass in expressive university buildings must satisfy multiple performance requirements simultaneously.

Structural Glass Design for Large-Span Skylights

Large skylights require careful coordination between the structural framing system and the glass panels. The curved steel arch supports a glass roof that spans the full width of the library, creating an uninterrupted view of the sky. For construction professionals, the following factors govern skylight performance in institutional projects:

1. Glass thickness and lamination must satisfy structural load requirements while maintaining optical clarity
2. Thermal break details prevent condensation and heat loss at the glass-to-frame interface
3. Shading strategies reduce solar heat gain without blocking the view
4. Waterproofing details at the perimeter must accommodate thermal movement while remaining watertight for the life of the building
5. Maintenance access provisions must be integrated into the design from the outset

Solar Control and Daylighting Performance

The curving bowed roof on top of the structure provides solar shading from the harsh Floridian sun while also invoking sinuous avian forms. This integration of passive environmental control with architectural expression is a hallmark of well-executed university building design. The building envelope must balance the desire for transparency with the practical need to manage heat gain, glare, and UV exposure.

Modern glazing solutions for institutional buildings include ceramic frit patterns, low-emissivity coatings, and dynamic glass technologies. When selecting glass for expressive architectural projects, contractors should consider how bird-friendly glazing in building envelopes affects both sustainability ratings and occupant comfort. The right combination of glass types can reduce cooling loads by 20 to 30 percent while maintaining the visual transparency that the design requires.

Roofing Strategies for Expressive Building Forms

The curved roof of the Embry-Riddle student union is one of the most visually distinctive elements of the project. Its sweeping form suggests the wing of a bird in flight while providing functional benefits including solar shading, rainwater management, and support for the exposed structural system. Roofing complex curved surfaces presents unique challenges for construction teams.

Material Selection for Curved Roof Assemblies

Standing seam metal roofing is often the preferred system for curved roof applications because the interlocking panels can be factory-curved to match the architectural geometry. The long-span capabilities of metal roof panels reduce the number of standing seams required, creating a cleaner visual appearance. When specifying standing seam metal roofing standards, contractors must confirm that the panel profile, gauge, and finish are compatible with the radius of curvature specified in the architectural design.

Alternative roofing materials for curved surfaces include liquid-applied membranes, zinc panels, and copper standing seam systems. Each material offers different aesthetic qualities and performance characteristics that should be evaluated against the project budget, climate conditions, and design intent.

Wind Uplift Resistance for Hurricane-Prone Regions

Buildings in coastal Florida must meet stringent wind uplift requirements. The exposed double arches that wrap the exterior of the student union support the vertical roof struts at the shading overhang, providing structural resistance against uplift forces while signifying the main entrances. The following table summarizes key wind design considerations for curved roof assemblies in hurricane-prone regions.

Curved roofs require additional attention to air barrier continuity because the changing geometry creates more complex air sealing conditions at ridge lines, eaves, and transitions. A single discontinuity in the air barrier can significantly reduce the overall wind uplift resistance of the assembly, leading to performance failures during severe weather events.

Programmatic Integration and Spatial Organization in University Buildings

The Embry-Riddle student union functions as an aeronautical athenaeum, combining social learning spaces, an events center, club offices, student affairs offices, career services, dining, and the university library within a single building. The programmatic organization of this 177,000-square-foot facility demonstrates how expressive architecture can accommodate complex functional requirements.

Triple-Height Commons as a Social and Circulation Hub

At the center of the building, triple-height commons integrate the collaborative social and learning environments. This approach to spatial organization provides several benefits for university building design:

• Natural light penetrates deep into the building through the tall glazed facades
• Visual connections between floor levels encourage interaction across student communities
• The dramatic vertical space reinforces the sense of aspiration and discovery
• Flexible gathering areas can accommodate everything from casual study to organized events

Designing multi-story atrium spaces in university buildings requires careful attention to acoustic control. Hard surfaces that create the desired visual effect can also produce excessive reverberation. The acoustic ceiling solutions specified for the atrium areas must balance sound absorption with the exposed structural aesthetic that defines the project.

Event Center and Amphitheater Integration

The first-floor event center accommodates up to 900 people and opens onto the commons, creating a seamless connection between large gatherings and daily campus life. A multi-story amphitheater overlooks the commons and building entry, providing informal seating and presentation space that activates the main circulation zone.

Key spatial organization strategies used in this building include:

1. Public functions (events, dining) located at ground level for easy access
2. Student services (career services, student affairs) distributed on the second floor around the commons
3. The library placed at the top floor beneath the arched skylight for quiet study with maximum natural light
4. The roof terrace on the second floor oriented toward the airport runway and Kennedy Space Center views

Creating a City within a City on Campus

The student union functions as a self-contained campus hub, providing all the services students need in a single iconic structure. This city-within-a-city concept reduces the need for students to travel between separate buildings for different services, creating a more efficient and engaging campus experience. For construction professionals, this means coordinating multiple building systems within a unified architectural vision.

When building programmatically complex institutional facilities, contractors must plan for the integration of diverse systems including food service equipment, library technology infrastructure, event center rigging and lighting, and IT networking for student services. The structural design must accommodate these varied loads while maintaining the visual expression that defines the building.

Conclusion

The Mori Hosseini Student Union at Embry-Riddle Aeronautical University demonstrates how expressive structural design can transform a university building from a functional facility into an iconic landmark. By using architecturally exposed structural steel, dramatic glazing systems, and curved roofing forms, the design team created a building that embodies the values of aviation and aerospace education while meeting the complex programmatic requirements of a modern student union.

For building professionals working on institutional projects, the lessons from this project extend beyond the specific design details. Successful expressive architecture requires early coordination between structural engineers, architects, and construction teams to ensure that the visual intent can be realized within budget and schedule constraints. Material selection must balance aesthetic goals with performance requirements, particularly in challenging climate conditions. And the building program must be organized in a way that reinforces the architectural concept rather than competing with it.

University buildings that successfully express institutional identity create lasting value for their campuses. They attract students, inspire learning, and become symbols that resonate with the community for decades. As more universities seek distinctive architectural expressions of their missions, construction professionals who understand the principles of expressive structural design will be better equipped to deliver projects that meet both functional and aspirational goals.
