Steel Structure Design Considerations for Port Storage Silo Construction at Pointe-Noire, Central Africa: Building Along the Tropical Coastline

-
图片
The port of Pointe-Noire in the Central African Republic, situated on the Atlantic coast, serves as the nation's vital economic gateway. The region experiences a typical tropical maritime climate characterised by year-round high temperatures and humidity, abundant rainfall, and strong sea breezes. As a port area, the terrain is generally flat, though it may encounter issues with foundation bearing capacity and tidal influences. Pointe-Noire Given these climatic and topographical characteristics, the following preliminary steel structure design proposal aims to provide guidance for constructing storage warehouses at Black Point Port.   Why choose steel structures ? In environments such as Black Point Port, steel-framed storage warehouses offer distinct advantages: Efficient construction: Steel components can be prefabricated off-site and rapidly assembled on-site, significantly reducing the construction timeline. For port projects, this translates to faster operational readiness an...

 Bolt Ball Testing Methods

bolt ball



1, bolt ball and manufacturing bolt ball nodes need materials, its varieties, specifications, performance, etc. should comply with national product standards and design requirements.
Inspection methods: check the quality of the product qualified documents, Chinese signs and inspection reports, etc.
2、Bolt ball shall not have burn, crack and crease.
Inspection method: Sample part of each specification of bolt ball, observe with 10 times magnifying glass and surface inspection.
3, bolt ball thread size and thread tolerance should be in line with the current national standard provisions.
Inspection method: check a part of each specification of the bolt ball and measure it with a standard thread gauge.
4, bolt ball diameter, roundness, adjacent two bolt hole centre line angle and other dimensions and allowable deviation should be in line with the local steel structure acceptance regulations.
5、Inspection method: Sample a portion of each specification of bolt ball and check if it conforms to the specified value with calipers and indexing head gauge.

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...

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...

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...
