Dome buildings have eye-catching exterior shapes. Their rounded curves are unique in the architectural landscape and easily become the visual focus. In this article, we will explore the history and development of dome buildings, structural types, advantages, and innovative designs. Reading this article, you will learn that they are not only beautiful but also practical.
Dome Buildings Overview
The history of the dome dates back thousands of years, as far back as ancient Mesopotamia (modern-day Iraq). Later, the Romans made considerable improvements to dome buildings. Completed in 125 AD, the Pantheon, the most famous Roman dome, is one of the few remaining ancient buildings in nearly perfect condition. In the past, building domes were more closely associated with religion and were widely used in churches.
With the advancement of materials and technology, people have more innovative and bold designs for dome buildings. They began to develop towards modernization, with larger spans and lighter designs, and their applications were no longer limited.
Types of Dome Buildings
There are many types and styles of dome buildings. To give you a better understanding of the types of domes, this article will introduce them from three aspects: shape, frame material, and outer cover material.
Type by Shape
- Geodesic Dome
The geodesic dome was popularized by Buckminster Fuller. It is a structure composed of mutually supporting triangles, which have good stability. Even with a large diameter, the structure can support itself and withstand external weight and pressure well. This advantage makes the geodesic dome widely used, such as exhibitions, greenhouses, stadiums, etc.
- Onion Dome
The onion dome is a special element, usually round or spherical, with a cross spire on top. Its shape is elegant and round and looks like an onion from a distance, hence the name. This type of building is common in traditional Russian and Eastern European architecture and is usually closely related to religious beliefs, cultural traditions, and local characteristics.
- Ribbed Dome
The characteristic of a ribbed dome is that it is made up of many ribs that extend outward. These ribs are distributed on the surface or inside the dome to form a supporting grid. These ribs are usually made of materials such as stone, concrete, or steel, which help to increase the stability and load-bearing capacity of the structure. This design style is widely used in Gothic and Islamic architecture.
Type by Frame Material
- Steel Dome
Steel dome buildings are made of steel frames, usually connected by welding or bolts. They have high strength and high tensile strength and are suitable for large-span designs. Steel can withstand large loads and is not prone to breaking. Moreover, steel can be prefabricated in factories, so dome steel buildings construction speed is fast.
- Concrete Dome
This type of dome is mainly made of concrete and is suitable for long-term use. It is highly fire-resistant. However, the construction of a concrete dome requires a permit and takes a long time. Due to the heavier concrete structure, the entire building is heavier, so a solid foundation is required.
- Wooden Dome
Wood is a natural renewable material, wooden dome is a good choice if you want to reduce your carbon footprint. The wooden dome has a certain aesthetic appeal, and the unique texture of the wood makes people feel warm, which is suitable for buildings that need to be beautiful. However, this material is susceptible to pests, rot, and other problems, and requires regular inspection and maintenance.
Type by Cover Material
- PVC Dome
PVC is a common dome material. It has the advantage of being lightweight. In addition, it is tear-resistant, UV-resistant, and waterproof. The applicable temperature of PVC is -30~70℃, which means it can adapt to most weather conditions but cannot be used in extreme conditions. PVC domes are suitable for occasions that need to be moved or adjusted, and their cost is relatively low, making them an affordable choice.
- PVDF Dome
PVDF has superior properties to PVC, especially in terms of temperature resistance and corrosion resistance. It is suitable for harsh climate conditions. However, despite its superior performance, the PVDF dome is also more expensive than the PVC dome, which makes it suitable for projects with sufficient budgets and high-performance requirements.
- Glass Dome
The characteristics of a glass dome are to provide maximum natural light and reduce dependence on artificial lighting. The transparent roof can provide 360-degree outdoor landscape angles, which can bring a more open and bright space. Due to the good light transmittance of the material, the glass dome is very suitable for greenhouses and can bring sufficient sunlight and reliable protection for plant growth.
Benefits of Dome Buildings
Dome buildings have received increasing attention in recent years, standing out for their unique design and numerous advantages. Their unique appearance and practical functions make them an ideal choice for various applications.
Stable Structure
The shape of the dome can effectively even out and bear various loads, including wind loads, snow loads, etc. Compared with traditional flat roof structures, domed buildings have more advantages. In windy or snowy areas, dome buildings can better withstand the impact of severe weather and reduce the risk of structural damage.
Efficient Use of Space
Dome buildings can be said to be a model of space utilization. They can obtain more usable space than ordinary buildings with the same floor area. Usually, no columns are inside, and it is a large continuous space. It encapsulates the largest volume with the smallest surface area, showing a unique and efficient use efficiency.
Unique Acoustic Properties
The curved structure of the dome helps to reflect and scatter the sound. The curved structure plus the smooth surface can evenly disperse the sound at all angles, avoiding the concentration of sound and reducing echo. This structure can satisfy the audience's auditory experience, making it an ideal place for concerts and theaters.
Save Energy
Dome buildings have excellent energy efficiency and can greatly reduce the use and loss of resources. Due to its small size, it will use less material costs than a conventional building. Moreover, buildings domes often have large openings or use transparent materials, which allows for ample natural light and reduces reliance on artificial lighting.
Innovative Dome Designs
With the advancement of materials and technology, dome design is also constantly innovating. From traditional stone to the application of modern materials, the dome is not only more efficient and stable in structure, but also presents more possibilities in design concept. Next, we will introduce the innovative design of dome architecture from 3 aspects.
Use Lightweight and High-strength Materials
Compared with the heavy materials such as bricks, mud, and stones used in ancient times, modern dome design now uses modern new materials. These materials will be relatively lighter, perform better, and can withstand higher levels of pressure. For example, common metal dome buildings, glass dome buildings, fabric dome buildings, etc. High-quality and diverse materials make the dome design widely used.
Self-assembling Domes
More and more dome buildings use modular construction systems, which means you don't need to spend half a year or even longer to build a dome. This modular design allows you to assemble the dome yourself. If it is a large dome, you can assemble it with the help of robots or mechanical systems, which greatly saves time and labor costs and speeds up the assembly process more than before.
Focus on Sustainable Development
Modern buildings are increasingly focusing on energy and sustainable development, and the dome building is no exception. Most of them use reusable materials, such as steel and aluminum alloy. These materials are not only environmentally friendly but also have a long service life. In addition, the dome metal building will take advantage of natural lighting and use technologies such as solar exhaust fans to reduce the impact on the environment.
Conclusion
Now, you have learned about the development, types, advantages, and innovative designs of dome buildings. With its unique structure and excellent performance, dome buildings have become a popular choice for modern architecture. If you want to learn more about domes, please feel free to contact us.
