What are the challenges in structural design for irregularly shaped buildings?

The structural design of non-standard geometric buildings represents the most critical and challenging aspect of their realization. The difficulties extend far beyond merely “how to make it stand,” permeating the entire process from concept development and calculations through construction and use. Below are the primary challenges in the structural design of non-standard geometric buildings, presented in order from core to derivative issues: 1. Core Mechanical Challenge: Non-Standard Load Paths In traditional buildings (such as rectangular boxes), load transfer paths are clear and direct: floor slab → beam → column → foundation → ground. Forces are primarily transmitted vertically downward. In contrast, load paths in irregularly shaped structures are often highly complex and convoluted. Challenge: Forces do not obediently travel straight downward. They “detour” through curved surfaces, diagonal bracing, and irregular grids, generating massive torsional forces, bending moments, and hor...

Characteristics of steel structure building

-

 1. High strength, light weight

The strength of steel is high, and the elastic modulus is also high. Compared with concrete and wood, the density and strength of steel are relatively low, so under the same stress conditions, the steel structure has the characteristics of small cross-section, light weight, convenient transportation and installation, and is suitable for large-span, high-height and heavy-duty structures.

2. Good toughness, high reliability

The steel is suitable for bearing impact and dynamic loads and has excellent seismic performance. Its internal structure is homogeneous and almost isotropic. The actual performance accords with the calculation theory. Therefore, the reliability of the steel structure is higher.

3. High degree of mechanization

Steel structural components are easy to manufacture in the factory and assemble on site. The steel structure component factory has high precision, high production efficiency, fast assembly speed and short construction period. Steel structure is one of the most industrialized structures.

4. The steel structure has good sealing performance

Because the steel structure is welded, it can be completely sealed to make high pressure vessels, large oil pools and pressure pipelines with good air tightness and water tightness.



5. Steel structure is heat resistant, but not fire resistant

When the temperature is below 150℃, the properties of steel do not change much. Therefore, the steel structure is suitable for high temperature workshops, but when the surface of the structure radiates about 150 ° C, heat insulation panels should be used for protection. When the temperature is between 300 and 400 ° C, the strength and elastic modulus of the steel are significantly reduced, and the strength tends to zero around 600 ° C. Buildings with special fire protection requirements shall use refractory materials to improve the fire resistance grade.

6. Poor corrosion

Steel rusts easily in humid and corrosive environments. General steel to rust, galvanized or painted, and regular maintenance. Special measures should be taken to strengthen the corrosion resistance of offshore platform structures in seawater.

7. Go green

The demolition of steel structures almost does not produce construction waste, and its steel can be recycled and reused, which is very environmentally friendly.

What is a coal bunker?

-

Coal bunker , is a structure used for storing coal. Coal bunkers play an important role in thermal power plants, coal mines and coal marshalling stations. Depending on the specific application scenario and design, there are various types of coal bunkers, such as circular coal bunkers, square coal bunkers and open coal yards. Safety Management of coal bunkers Preventing spontaneous combustion of coal: Since coal itself contains certain moisture and volatile substances, long-term exposure to the air may lead to spontaneous combustion, so the safe management of coal bunkers is of great significance in preventing spontaneous combustion of coal. Ensure the quality of coal: coal in the coal bunker usually needs to be stored for a long time, if not managed properly, it may lead to the decline in the quality of coal, such as sulphurisation, weathering and other phenomena, so it is necessary to ensure the quality of coal by strengthening the safety management of the coal bunker. Improve the eco...

What is the difference between a single-layer reticulated shell and a double-layerreticulated shell?

  The differences between single-layer reticulated shells and double-layer reticulated shells are as follows: Structural Configuration   Single-layer reticulated shell: Composed of a single layer of members, with the members directly connected to form a grid structure . The node configuration is relatively simple, typically employing rigid connections that allow the members to bear not only axial forces but also bending moments and shear forces.   Double-layer reticulated shell: Consists of upper and lower parallel layers of members connected by web members, forming a truss-like structural system. The nodes are generally hinged, and the members primarily bear axial forces. Its configuration is relatively complex, requiring more members and nodes to ensure structural stability and load-bearing capacity. Structure Single-layer mesh shell: composed of one layer of rods, the rods are directly connected to form a mesh structure, the node structure is relatively simple, usually...

Suspension structures

 A suspension structure is a structural form that carries roof loads through a series of high-strength steel cables. Its main load-bearing member is the cables, which are usually steel cables made of high-strength steel wires. The roof of the suspension structure is generally light and thin, and its shape can be very flexible, able to realize the large span across. For example, in the roofs of some large conference centers or exhibition halls, the suspension structure can create unique shapes such as double-curved paraboloid or single-curved paraboloid, which make the building have a strong artistic influence. Suspension structures require a stable support structure to anchor the steel cables, usually using reinforced concrete columns or steel columns as support. And in order to ensure the stability of the structure, it is also necessary to set a certain amount of prestressing, so that the steel cables are in a tensioned state before they are subjected to loads. Scope of applicatio...
