Project Challenges: Double Impact of Typhoons and Earthquakes The coal storage bunker of Power Plant in the Philippines has been facing tests from extreme natural conditions since the planning stage: Climate Challenge : Located in a super typhoon zone with wind speeds of up to 260 kilometers per hour, it withstands fierce storms and heavy rains every year. Geological Threat : Situated in a high seismic intensity zone with Z=0.4, the structural stability must be absolutely guaranteed. Cost Pressure : The client requires strict control over overseas construction costs while ensuring safety, and also demands controllable construction periods. Ultra-Large Scale : With a total height of 48.675 meters and a foundation height of 3.0 meters, the long-span dome design poses a great challenge to structural strength for industrial projects. Solutions: Comprehensive Upgrades from Design to Materials Targeting these pain points, our overseas engineering team has tailor-made a combined solu...

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...

What is the difference between a single-layer reticulated shell and a double-layerreticulated shell?

  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...

 It is widely used in modernist architecture. Steel structure installation is mainly carried out by electric welding welding and bolts. Because the steel frame structure is compact and practical, it brings great convenience to engineering construction. In order to promote the sustainable development concept of steel frame structure in the construction engineering industry, it is necessary to carry out an in-depth analysis of the construction stage of steel structure, especially the node design, to ensure reliability.       Steel plate materials are widely used in modernist buildings because of their extreme seismic performance, plasticity and reliability. Jiangsu steel structure project construction is to be processed with bolts or steel to make the building structure. Accompanied by the improvement of living standards and the rapid development of the construction industry, the requirements for steel frame structure are rigorous. As a result, the design of steel fra...
