The Importance of Foundation Design for Steel Silo Stability

-
图片
  The foundation of an industrial steel silo is its unsung hero—while the silo’s steel structure is visible and often the focus of attention, the foundation bears the entire weight of the silo and its stored materials. A poorly designed or constructed foundation is the leading cause of steel silo instability, leading to issues like uneven settlement, tilting, wall bending, and even structural collapse. For project contractors, facility owners, and engineers, prioritizing foundation design is not just a construction requirement; it’s a critical step in ensuring the long-term safety, stability, and durability of steel silo projects. Steel silos are unique in their load requirements—they carry heavy, concentrated loads (often thousands of tons of bulk materials like coal, cement, or ores) and are often exposed to external stresses like wind, snow, and seismic activity. Unlike other industrial structures, a steel silo’s foundation must distribute these loads evenly across the soil to a...

Application of space frames to hangars

-

To date, space frame structures have been widely used in China, with application scenarios including but not limited to: industrial plants, coal storage structures, hangars, airport terminals, high speed rail stations and large stadiums.

💚💚💚

Hangars require a large span and space sufficient for aircraft parking, but also a certain load-bearing capacity to withstand the loads brought by the equipment during aircraft maintenance. In order to increase the load-bearing capacity, the construction of hangar structures has been accompanied by improvements and innovations to the traditional two-storey space frame structure. For example, the four-bay hangar at Beijing Capital Airport, built in 1996, has a three-storey space frame structure with dimensions of (153+153)m × 90 m. The hangar of China Southern Airlines at Beijing Daxing International Airport, built in 2019, has a W-shaped truss + space frame structure system with a span of 222 m at the opening side of the gate.

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...

Structural Steel Bolting Balls: Connecting the Future, Securing the Cornerstone

-
图片
In the field of steel structure , bolted ball, as an innovative choice of connecting node, is gradually becoming the preferred solution in modern buildings and industrial facilities due to its advantages of easy installation, removable and reorganisable, and low maintenance cost. Compared with traditional welded balls, bolted balls not only simplify the construction process and improve efficiency, but also give the structure greater flexibility and sustainability, which is an indispensable and important component in modern steel structure projects. The core concept of the bolted ball connection technology is to use high-strength bolts to closely connect the components to form a stable and reliable node structure. Compared with welded ball, bolted ball connection does not require on-site welding and avoids thermal stress, deformation and weld quality problems that may arise during the welding process, thus improving the overall stability and safety of the structure. In addition, the bo...
