Shell Structure

Thin, curved surfaces for structural efficiency.

Overview

Shell structures use concrete for thin, curved surfaces that maximize strength with minimal material.

Core Characteristics

• Thin and lightweight.
• High structural efficiency.
• Modern aesthetic.

Notable Examples

• Sydney Opera House (Australia, 1973, concrete shells).
• TWA Flight Center (USA, 1962, shell structure).

Architectural Connections

• Modern: Structural focus.
• Cultural: Iconic buildings.
• Modernism: Core movement.

Influence and Legacy

Led by Eero Saarinen, it advances structural innovation.
