AESS

Definition

Architecturally Exposed Structural Steel (AESS) refers to structural steel that is designed to be visible in the finished structure and therefore requires a higher level of finish, craftsmanship, and aesthetic consideration. Unlike regular structural steel, which is typically concealed by other building materials, AESS is intended to be a prominent architectural feature.

Purpose

The purpose of AESS is to combine structural functionality with aesthetic appeal. It serves both as a crucial load-bearing component and as an architectural element that enhances the visual appearance of the building. AESS is often used in modern architecture to showcase the elegance and strength of steel, contributing to the overall design and character of the structure.

Examples of Use

1. Commercial Buildings: In commercial buildings, AESS can be used in atriums, lobbies, and other public spaces where the steel structure is intended to be a visual focal point.
2. Bridges: Many modern bridges use AESS to create visually striking designs that highlight the structural elements while ensuring durability and strength.
3. Cultural and Civic Buildings: Museums, galleries, and other cultural buildings often incorporate AESS to blend functionality with artistic design, making the structural elements part of the visual experience.
4. Stadiums and Arenas: The exposed steel framework in sports stadiums and arenas is often designed as AESS to create an open, industrial aesthetic while supporting large spans and heavy loads.
5. Residential Architecture: In high-end residential buildings, AESS can be used to create unique architectural features such as exposed beams, staircases, and railings.

Related Terms

1. Structural Steel: Steel used as a structural material in building and construction, typically concealed by other materials in standard construction.
2. Architectural Steel: Steel used primarily for its aesthetic qualities in addition to its structural properties.
3. Steel Fabrication: The process of cutting, shaping, and assembling steel components for construction.
4. Exposed Concrete: Similar to AESS, this refers to concrete surfaces that are designed to be visible and require a higher level of finish.
5. Industrial Aesthetic: A design style that emphasizes raw, unfinished materials like steel and concrete, often featuring exposed structural elements.

Notes

• AESS requires a higher level of detailing, fabrication precision, and surface finish compared to standard structural steel.
• Standards and guidelines, such as those provided by the American Institute of Steel Construction (AISC), help define the quality and appearance requirements for AESS.
• The fabrication and erection of AESS often involve close collaboration between architects, structural engineers, and fabricators to ensure the aesthetic and structural goals are met.
• Protective coatings and finishes are commonly applied to AESS to enhance its appearance and protect it from corrosion and wear.
• The use of AESS can increase the cost and complexity of a project due to the additional labor and materials required to achieve the desired aesthetic quality.
