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

图片
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...

What are the structural forms of steel space frames?

-

 Steel space frame is a special type of steel structure, usually used to support large-span roofs or to construct special shaped buildings. It can be used in a variety of structural forms, the following are the common ones:

 

space frame

  • Rigid Frame Structure: Rigid frame structure is a rigid frame composed of steel rods, nodes and connectors, which can withstand vertical loads and horizontal loads. Rigid frame structures are often used for large-span buildings, such as gymnasiums and exhibition halls.
  • Arch structure: Arch structure is a graceful curved form, often used in large-span buildings, especially spherical or domed gymnasiums and exhibition halls. Arch structure can withstand the pressure and spread the load to the fulcrum.
  • Dome structure: Dome structure is a special form of arch structure, usually used in domed buildings, such as planetariums, domed stadiums, etc.
  • Grid Shell Structure: Grid Shell Structure is a grid-like structure composed of many interconnected thin-walled bars, usually used to create large-span roofs with curved shapes, such as gymnasiums, exhibition halls and so on.
  • space frame structure: Grid structure consists of intersecting rods that can form a planar or spatial space frame, usually used for large-span buildings. 
  • Truss structure: Truss structure is a triangular structure composed of rods and nodes, which can effectively bear loads and keep stability, and is commonly used in bridges and large-span roofs.
  • Space Rigid Frame Structure: Space Rigid Frame Structure is a three-dimensional structure composed of many interconnected rigid frames, which can be used to support large-span buildings, such as gymnasiums, airport terminals and so on.
  • Double-storey space structure: double-storey space structure is a complex structural form, commonly used in buildings requiring multi-storey space layout, such as gymnasiums, exhibition halls and so on.

These structural forms can be used individually or in combination in a building project to meet different design needs and functional requirements. The choice of the appropriate structural form depends on the specific use of the building, the environmental conditions and the creativity and technical ability of the designer.

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?

-
图片
  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...
