Theoretical Basis of a Structural Strategy for an Art Gallery

Structural Expression and Spatial Experience

The described structural strategy exemplifies a deliberate move beyond conventional rectilinear “box-like” forms to one that visually and experientially reflects the spatial dynamism within the building (Frampton, 1995). The inclination of end walls, tapering inner walls, and conical entrance form challenge typical orthogonal structural logic, requiring an approach that expresses architectural form through structure without excessive internal partitioning or loss of volumetric spaciousness (Kolarevic, 2003). This ambition aligns with tectonic architecture principles, where structure is not concealed but celebrated as a medium of spatial and formal expression (Frampton, 1995). Instead of a two-layer system—one for the exterior enclosure and another internal frame for spatial shaping—the design merges these aspects through a primary steel frame that both defines and supports the building’s form, and a robust reinforced concrete interior that addresses functional requirements.

Composite Structural Systems: Steel Frame and Reinforced Concrete Integration

The integration of a steel lattice frame supporting a reinforced concrete floor slab system optimizes both flexibility and load-bearing capacity, crucial in art galleries where floor loads vary significantly due to large-scale sculptures and installations (Allen & Zalewski, 2010). Steel framing offers a lightweight, adaptable envelope, while concrete slabs and beams provide the high load resistance and stiffness necessary for heavy exhibits (Gere & Timoshenko, 1999). This composite structural strategy allows separation of roles—the steel frame forms the external “skin” and spatial framework, while the concrete core and slabs deliver structural robustness internally, enhancing adaptability to changing exhibition layouts without compromising structural integrity (MacGinley, 2013).

Lattice Frames and Modular Geometry

The use of a steel lattice frame composed of straight members—eschewing curved structural elements—demonstrates a sophisticated approach to generating complex architectural forms through modular, rational geometry (Kolarevic, 2003). This approach reduces fabrication complexity and cost while enabling the angular and inclined surfaces that define the gallery’s distinctive external and internal spaces. Such lattice structures can efficiently span large distances with reduced member sizes, accommodating cantilevered volumes and open gallery spaces with minimal internal supports (Bechthold, 2007). Moreover, lattice frames lend themselves well to the attachment of façade panels, glazing, and solar shading elements, facilitating a high degree of façade articulation and environmental control.

Structural Solutions for Cantilevered and Console Elements

The gallery’s cantilevered upper floors and consoles are supported by reinforced concrete shafts and consoles, which act as both load-transfer points and architectural features (Gere & Timoshenko, 1999). These concrete elements provide the necessary rigidity and mass to counterbalance cantilever moments and are expressed externally, visually reinforcing the building’s structural logic. This strategy illustrates the potential of hybrid steel-concrete systems in combining the tensile strength and flexibility of steel with the compressive strength and mass of concrete, enabling bold structural gestures that define spatial drama while ensuring durability and stability (Blaser, 2003).

Secondary Structural Systems and Flexibility for Exhibition Needs

The design minimizes the use of secondary steelwork by integrating primary and secondary structural elements, ensuring the primary steel frame also supports secondary functions such as screen supports and solar shading devices (Allen & Zalewski, 2010). This reduces structural complexity and material use, leading to efficient load paths and clean architectural expression. The screens fixed back-to-back on the primary structure support flexible exhibition layouts, allowing reconfiguration without structural intervention. This adaptability is critical in a gallery context where the spatial requirements and load distributions vary with changing exhibitions (Blaser, 2003).

Environmental Controls and Structural Integration

The rooftop arrangement of solar louvres as environmental controls exemplifies how structural design facilitates climate responsiveness in a temperate environment (Lechner, 2014). The steel framing supports these elements, ensuring they are structurally stable yet modular and adjustable, contributing to solar shading and daylight management critical for art conservation and visitor comfort. The integration of translucent and opaque glazing panels with the steel structure balances daylight provision with thermal performance, reinforcing the role of structural design in mediating the building’s environmental interface (Givoni, 1998).

Option Variations and Structural Adaptability

The structural strategies outlined for the three options—ranging from multiple linked steel frames with varying geometries (Option 1), curved roof framing (Option 2), to integrated primary-secondary framing without curved members (Option 3)—highlight the flexibility of steel as a material and lattice structures as a system in accommodating diverse architectural forms (Kolarevic, 2003; Bechthold, 2007). This adaptability ensures that structural systems can be tailored to site constraints, aesthetic goals, and functional requirements without compromising on constructability or performance.

Overview

The structural strategy of this art gallery project synthesizes architectural ambition with engineering pragmatism through: Use of steel lattice frames composed of straight members to create dynamic, non-rectilinear forms economically and efficiently. Integration of reinforced concrete cores and slabs providing heavy load capacity and stability for large installations. Expressive structural elements, such as cantilevered concrete consoles, which articulate the building’s spatial drama. Minimal secondary steelwork with primary structure supporting flexible internal exhibition elements and environmental controls. Responsive environmental integration through rooftop shading and glazed panels, supported structurally to optimize natural light and thermal comfort. This approach demonstrates how contemporary structural design can serve as both a functional necessity and a medium for architectural expression, especially in cultural buildings that demand spatial complexity, adaptability, and environmental sensitivity.
