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...

Why do large showrooms hall prefer steel structures space frame ?

showrooms  hall

There are several reasons why large exhibition halls like to adopt steel structure space frame:

  • Structural stability and load-bearing capacity: Steel space framecan provide high structural stability and load-bearing capacity, which can support large-span roofs or ceilings, making the internal space layout of the showroom more free and flexible.
  • Large-span design: Steel space framecan realise large-span design without intermediate support columns or walls, thus providing a greater sense of space and making the exhibition space more open.
  • Construction Efficiency and Speed: The fabrication and installation of steel space frameis relatively more efficient and fast than traditional concrete structure, which is very important for large-scale projects and can shorten the whole construction cycle.
  • Adaptability: Steel structures can be adapted to a variety of climatic and geological conditions, and can maintain stability in harsh environments, as well as strong resistance to earthquakes and wind.
  • Sustainability and recyclability: Steel can be recycled, which is conducive to the sustainable use of resources and also reduces the dependence on natural resources.
  • High degree of freedom in appearance design: Steel structures are flexible in design and can be realised in a variety of shapes and styles, allowing the appearance of the showroom to be customised according to design requirements.
  • Relatively low maintenance cost: steel structure is generally less costly to maintain in the later stage compared with other materials.
To sum up, the use of steel structure space frame can provide stable, safe and efficient structural support for large-scale exhibition halls, and at the same time, it can also provide greater freedom and flexibility in the design and construction phases, which is in line with the characteristics of large-scale exhibition halls in terms of spatial requirements.

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...
