Glenn KatzOverall Strategy and the Features of the Structural System
In developing the structural design of the exhibition center, I meticulously aligned the entire grid structure with the architectural motif presented by the roof. This decision not only serves a structural purpose but also harmonizes with the building’s distinctive diamond shape, ensuring both aesthetic and functional coherence. The adoption of a steel structure was pivotal in this design, leveraging steel's superior load-bearing capabilities while optimizing space utilization.
Structural Components and Design Choices
- Steel Columns: The structural framework incorporates W-shaped steel columns, each measuring 12ft by 50ft. These are supported by pad footings with dimensions of 2400mm x 1800mm x 450mm, providing a solid foundation for the building's load requirements.
- Foundation and Flooring: A foundation slab of 150mm thickness forms the base of the first level, enhancing stability and support.
- Beam Systems: The primary beams, featuring a W shape of 16ft by 26ft, are a critical component of the structure. On the first floor, the beam system employs W-shaped steel beams measuring 12ft by 22ft, arranged with a fixed spacing of 6 feet. This configuration adapts to the building's diamond-shaped grid, with the north section following a conventional rectangular beam system, while the east, west, and south sections mirror the diamond layout.
Level 1 Primary Beams and Beam Systems
- Second Floor Adaptations: To accommodate and showcase the solar glass roof, the second-floor design incorporates larger major beams, eliminating the need for a smaller beam system. This open design strategy not only enhances aesthetic appeal by providing unobstructed views of the solar glass roof but also maximizes daylight penetration, aiding in heat retention during New York's winter months. The major beams on this level are sloped to align with the roof, introducing triangular configurations for added structural stability without excessive beam use.
Level 2 Beam System
Efficiency and Aesthetics: Both floors are designed with spans not exceeding 50ft, negating the need for additional trusses. This approach underscores a commitment to creating a stable, efficient structure that resonates with the building’s innovative and sustainable ethos, without compromising on the visual and functional integrity of the space.
