Selection and Application of Structural Steel Materials for Aircraft Maintenance Hangars​

-
图片
 Aircraft maintenance hangars , as the core facilities for aircraft inspection and repair operations, must endure long-term exposure to large-span loads, extreme weather conditions, and complex operational environments. Consequently, stringent requirements are imposed on the strength, weather resistance, and stability of the structural steel materials employed. The judicious selection of suitable steel structural materials not only ensures the hangar's safe operation but also reduces construction and maintenance costs. Based on the functional requirements of different structural components within the hangar, commonly used steel structural materials can be categorised into three main types, each playing a critical role in hangar construction. I. Primary Load-Bearing Structure: The Core Material Supporting the Hangar's ‘Skeleton’ The primary load-bearing structure forms the hangar's ‘skeleton’, bearing the hangar's own weight, aircraft parking loads, and external forces s...

Why do most of the stadium bleachers use truss structure?

-

 The reasons for adopting truss structure for stadium grandstand are as follows:

truss roof

1. High strength: Joist structure is composed of multiple triangles, which can disperse the load and support the weight, with high strength and stability.

2. Lightweight: truss structure is usually made of lightweight materials, such as steel or aluminum alloy, which is light in weight and easy to transport and install.

3. Good flexibility: Joist structure can be adjusted and changed as needed to suit different sites and usage requirements.

4. Economical and practical: The manufacturing cost of joist structure is relatively low and the maintenance cost is also low, so it is economical and practical.

5. Beautiful and generous: Joist structure has simple and generous appearance and good aesthetics, which meets the aesthetic standard of modern architecture.

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...

Unlock Expansive Designs with Steel Space Frame Roofing

-
图片
Dreaming of vast, uninterrupted interior spaces for your next project? Steel space frame roofing offers a powerful and efficient solution for achieving impressive clear spans. Their unique three-dimensional truss system distributes loads effectively, allowing for lightweight yet incredibly strong structures ideal for arenas, warehouses, and commercial centers. At SAFS Steel Structure, we specialize in designing and delivering these innovative roofing systems. One key advantage of steel space frames is their efficient use of materials. The triangulated design maximizes strength while minimizing steel tonnage, leading to potential cost savings. Furthermore, the modular nature of space frames facilitates efficient prefabrication and streamlined on-site assembly. This faster construction timeline can significantly reduce overall project costs and accelerate occupancy. Beyond structural efficiency, space frames offer significant design flexibility. Architects can create ...
