Study Notes
Course Content Overview
- The course, "Flat Geometric Shapes, Properties & Interpretation," is a first-year project theory course at the University of Algiers 1, Faculty of Sciences, Department of Architecture.
- The course duration is 2023-2024.
- The course instructor is Dr. DJEDOUANI Racha.
Introduction to Geometric Shapes in Architecture
- Geometric shapes in architecture are more than just aesthetics; they also have functional, structural, and symbolic implications.
- Architects use geometric shapes to create spaces that are visually appealing, functional, and architecturally meaningful.
Definition of Geometric Shape
- A geometric shape is defined by boundaries, lines, or edges with specific mathematical properties.
- These shapes have characteristics like length, width, height, angles, and proportions.
Basic Concepts of Geometry
- Fundamental concepts like points, lines, angles, polygons, and circles are crucial for understanding geometric shapes used in architecture.
1. Points
- Points are the basic building blocks in geometry.
- In architecture, points represent precise locations in space (often described using coordinates x, y, z).
- Points serve as reference markers for defining other geometric elements, and are the foundation for layout and measurement.
2. Lines
- Lines (connected series of points) are one-dimensional geometric elements.
- Architects use lines to create frameworks for structures, define edges (walls, roofs), and influence the overall style and form of a building.
- Lines can be straight, curved, horizontal, vertical, oblique, and their intersections create angles.
3. Angles
- Angles are formed by the intersection of two lines.
- Understanding angles is vital in architecture for determining orientation, alignment of elements, and visual effects.
- Different angles (acute, right, obtuse, reflex, straight) create distinct visual effects and impact how a building interacts with light and space.
4. Polygons
- Polygons are two-dimensional shapes formed by connecting straight lines (three or more sides).
- Polygons are extensively used in architecture to design floor plans, facades, and layouts, influencing both aesthetics and functionality.
- Specific polygons (triangles, squares, rectangles, pentagons, hexagons, heptagons, octagons, and decagons) have particular properties, like the sum of interior angles.
5. Circles
- A circle is a closed curve where all points are equidistant from the center.
- Circles are defined by their radius (distance from the center to edge) and diameter (twice the radius).
- Architects use circles to create curved or circular elements, such as arches, domes, and circular windows.
Properties of Geometric Shapes
- Architects employ geometric shape properties like symmetry, asymmetry, proportion, and balance to create aesthetically pleasing, functional, and harmonious buildings.
1. Symmetry
- Identical halves of a shape, mirrored across a central axis or plane.
- Symmetry helps create balanced and formal appearances, common in classical buildings (palaces, government buildings).
2. Asymmetry
- The opposite of symmetry; the shape does not have mirrored halves.
- Used to create visual interest and dynamism, typical of contemporary architecture.
3. Proportion
- The relationship between different parts of a building or an architectural element in relation to the whole. Architectural principles use calculated ratios to create balanced and aesthetically pleasing structures.
4. Balance
- The distribution of architectural elements in space to avoid visual imbalance.
- Both symmetrical and asymmetrical arrangements ensure functionality and safety of the building.
Influence on Architectural Design
- Aesthetics: Shapes contribute to pleasing and classical aesthetics (symmetry, proportion), or contemporary character (asymmetry).
- Functionality: Well-proportioned or balanced shapes optimize functionality, ensuring stability in the face of wind and earthquakes.
- Comfort: Spatial proportions affect comfort. Well-designed interior proportions improve usability.
- Expression: Symmetry or asymmetry, and proportion are used to express architectural ideas visually (dynamic vs. stable).
Additional Architectural Concepts
-
Geometric Terminology:
- Plane: A flat surface extending infinitely.
- Elevation: An orthogonal view of a building façade or side, showing structure viewed externally.
- Section: An orthogonal view, revealing interior layout (an imaginary cut).
- Coordinates: Numerical values to specify points in space.
- Axis: An imaginary line used for rotation reference and defining symmetry.
- Regular Polygon: Polygons with equal sides and angles; used in designs.
- Tessellation: Repetition of a geometric pattern to entirely cover a surface.
- Architectural Examples: Specific examples of architecture are featured to illustrate application of geometric concepts (Heydar Aliyev Cultural Centre, Fallingwater, Villa Savoye, Sydney Opera House).
-
Scale and Projection:
- Scale: Reducing object sizes for practical representations (architectural plans).
- Projection: How an image is displayed on a surface.
-
Symbolism:
- Geometric shapes can represent cultural meanings in certain cultures (Circle = unity).
-
Innovation:
- Architects use complex geometric shapes for unique and innovative building designs.
-
Integration with Environment:
- Geometric shapes can be used to blend a building naturally into its surroundings (i.e. a pyramid-shaped building on a mountain).
Conclusion
- Understanding geometric principles is foundational to architect's skill, allowing them to create both functional and aesthetically pleasing structures.
