Introduction
Glitzcamp explains the basic concept of the geodesic sphere and its unique position in architecture. What are the effects of different structures on the geodesic sphere? Compare the characteristics, stability and applicability of each structure.
What is a Geodesic Sphere Frequency？
Each face of the inscribed icosahedron of the dome is a triangle. The side length of this dome triangle is further divided into equal parts to form a geodesic sphere, and the equal parts are the V numbers. The maximum length of each specification of rod that can be used cannot exceed the required value of the slenderness ratio.
Under this premise, the fewer the V numbers, the more material is saved. The more V numbers, the closer the structure is to a sphere. The reason why the geodesic dome is popular is that theoretically, the regular icosahedron is the structure that is closest to a sphere.
2V
2v geodesic sphere is the simplest spherical dome structure, consisting of two hemispheres with 12 vertices and 20 faces. The uniqueness of this structure lies in the simplicity and symmetry of its geometric shape. It is widely used and is usually used for small tents or temporary structures.
As a classic geodesic sphere, its construction involves several key principles, including geometric design, material selection and structural connection. Following these key principles, the 2v geodesic dome structure can achieve its unique aesthetic effect and functional requirements.
3V
The 3V geodesic sphere structure is a more complex spherical architectural design, combined with three hemispheres to form a more solid and stable spherical space. There are 18 vertices and 32 faces, which help to disperse and transfer structural loads. The 3V geodesic sphere has load-bearing capacity, and is often used in medium-sized geodesic dome homes or public buildings.
The 3V geodesic sphere structure is superior to the 2V geodesic sphere structure in terms of stability, and the construction difficulty and cost are relatively high. Due to its structural complexity, more sophisticated design and construction techniques are required.
4V
The 4V geodesic sphere is the most complex spherical dome structure, consisting of four hemispheres. Each hemisphere is a perfect semicircular shape. The four hemispheres are spliced together to form a complete spherical space. There are 24 vertices and 48 faces. Each hemisphere presents a beautiful curved surface. The 4V geodesic sphere provides maximum stability and load-bearing capacity. The construction difficulty and cost of the 4V geodesic sphere structure are relatively higher than those of 2V and 3V.
What Are the Differences Among the Three?
| 2V Geodesic Dome Structure | 3V Geodesic Dome Structure | 4V Geodesic Dome Structure | |
| Frequency | 2 | 3 | 4 |
| Number of Vertices | 12 | 18 | 24 |
| Number of Faces | 20 | 32 | 48 |
As can be seen from the table, as the frequency increases, the complexity of the spherical dome structure also increases, which is manifested in the growth of the number of vertices and faces. The 2V structure is the simplest, while the 4V structure is the most complex. This reflects the load-bearing capacity of the dome.
What Should I Consider When Choosing Different Geodesic Sphere Frequencies?
When choosing prefab geodesic domes of different frequencies, the following key factors should also be considered:
Structural Safety Requirements
- 2V geodesic sphere: Due to its relatively simple structure, its stability is low.
- 3V geodesic sphere: Compared with the 2V structure, the 3V structure has improved safety and load-bearing capacity.
- 4V geodesic sphere: The 4V structure uses more rods, has a more complex structure, and has higher safety. It can provide a spacious and stable space and meet complex functional requirements. In addition, the spherical design of the 4V structure also has a strong visual impact.
Budget and Cost
In terms of cost, the three spherical dome structures of 2V, 3V and 4V each have their own characteristics. The 2V spherical dome structure has an advantage in cost due to its relatively simple design and requires less materials, which is the lowest among the three structures. The cost of 3V is slightly higher than that of 2V structure, but it is more robust. The 4V spherical structure has the most rods and is the most complex and stable of the three structures. From this we can see that the cost is increasing from 2V to 4V due to the increase in rods.
At the same time, more rods mean an increase in weight during transportation, which will lead to an increase in transportation costs. The more rods, the more complex the structure, and more manpower and time are required to build it. The cost of manpower and time will also increase accordingly.
Construction Technology
- 2V geodesic sphere: The construction technology requirements of 2V structure spherical dome are relatively low, and the construction process of this structure is relatively simple and intuitive. Usually only basic assembly and fixing operations are involved. Even less experienced construction workers can do this job without particularly advanced skills.
- 3V geodesic sphere: The construction technology requirements of 3V structure are higher than 2V structure. Because its structure is more complex, more sophisticated craftsmanship and technology are required to ensure the robust and integrity of the structure.
- 4V geodesic sphere: The complexity and sophistication of 4V structure far exceeds that of 2V and 3V structures. Advanced technology and rich experience are required during the construction process to ensure the perfect splicing of each hemisphere and the stability of the overall structure.
Functional Requirements
- 2V geodesic sphere: 2V geodesic sphere is very suitable for temporary buildings and short-term use due to its simple structural design and low construction cost.
- 3V geodesic sphere: 3V geodesic sphere has improved space and functions compared to 2V structure, suitable for basic living and daily use, such as small houses.
- 4V geodesic sphere: It is suitable for large buildings with high requirements for space and function. For example, it can be used in large stadiums, museums, planetariums and other places to provide spacious and functional space.
| 2V Geodesic Dome Structure | 3V Geodesic Dome Structure | 4V Geodesic Dome Structure | |
| Structural Stability | Lower | Medium | Higher |
| Cost | Lower | Medium | Higher |
| Construction Technology | Lower | Medium | Higher |
| Application Scenario | Small Tents/Temporary Buildings | Permanent Residence | Large Event Venues |
| Material Consumption | Less | More | Even More |
