What are the key points to consider when establishing a mineral warehouse on the coast of Nigeria?

👉 Project location: Nigerian coast 👉 Project type: Mine warehouse (span 100 metres, length 125 metres) 1. Structural Design  Span and Length:  The mine warehouse has a span of 100 metres and a length of 125 metres, employing a large-span steel structure design to ensure structural stability and load-bearing capacity.  It is recommended to use a steel truss structure or space frame structure to meet the large-span requirements and optimise material usage.  The structural design must consider wind loads, seismic loads, and dynamic loads during the operation of the bucket wheel excavator. Foundation Design:  Since the project is located by the sea, the foundation may be relatively soft. It is recommended to use deep foundation design (such as pile foundations) to ensure structural stability.  Foundation construction must consider the impact of groundwater levels and saline-alkali environments, and foundation reinforcement should be carried out when necessa...

Features of truss

-

 



From the perspective of material layout (or distribution), the truss can be regarded as a latticed beam as a whole, and its overall mechanical performance is similar to that of the beam. In the detail structure, each rod is used to re-direct the force flow (the nodes between the rods are not overlapped, and the bending moment cannot be transferred), and the overall layout is basically consistent with the main stress trace. Each rod is a secondary force rod, which is only subjected to tension and compression

Truss, especially space pipe truss, is often made into arch. However, at this time, the arch is not a pure pressure arch, and the whole arch is still dominated by bending. We can also consider it as a curved beam in a certain sense. Of course, arch camber can increase the span capacity, and the role of "axial force" in the "beam" can not be ignored at this time, but in most cases, especially when the rise-span ratio is small, the bending is still the main part.

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...

Strength and stability analysis of grid steel structures

-
图片
 The strength problem of space frame steel structure refers to whether the maximum stress (or internal force) caused by the load of the structure or a single component exceeds the ultimate strength of the building material in a stable equilibrium state, so it is a stress problem. The value of ultimate strength depends on the characteristics of the material. For brittle materials such as concrete, its maximum strength can be taken, and for steel, its yield point is often taken.            The stability problem is different from the strength problem. It is mainly to find the unstable equilibrium state between the external load and the internal resistance of the structure, that is, the state where deformation begins to increase rapidly, so as to try to avoid entering this state. Therefore, it is a deformation problem. For example, for axial compression columns, due to instability and lateral deflection, a large amount of bending moment is added to the c...
