Application of steel structure

Steel structure of multistory and high-rise buildings

In the multi-storey and high-rise buildings, there are mainly multi-storey frame, frame-support structure, frame-shear wall structure, frame tube, suspension, giant frame and so on. Steel structure and high-rise buildings are widely used in modern society.

2. Roof structure of large span building

The larger the span of a structure is, the larger its dead weight will be. Reducing the dead weight of the structure is the basis of realizing the long-span structure. Due to the characteristics of high strength and light weight of steel structure, it is very suitable for the construction of large-span structure, and has been widely used in the large-span project now. For example, Beijing New International Convention and Exhibition Center designed by Beijing Architectural Design and Research Institute is composed of 8 main exhibition halls, each hall is 168m long and 70.2m wide. The roof is steel structure, and the main analysis frame is prestressed triangular pipe analysis frame with a span of 70.2m.

Steel structure of bridge

Steel structure Bridges have been widely used in recent ten years and will continue to emerge in the next few years. It gives full play to the characteristics of long span steel structure. The main structural system is "suspension bridge, cable-stayed bridge, analysis arch bridge, concrete filled steel tube bridge".

4 Industrial workshop

The steel structure is generally the framework of industrial plant, and the structural form is mostly the portal steel frame or rack composed of steel roof frame and step column, as well as the structural form of the roof made of grid frame. Steel structure industrial plant is widely used, such as: Indonesia central Java power plant steel structure project, this project used 12,000 tons of steel. The main plant area is 4im X I55m, with 18 short shafts and 4 long shafts. The connection between steel column, steel beam and diagonal brace is bolt connection, which requires high processing progress of steel, and belongs to the type of difficult production in steel structure industrial plant.

5 Removable structure

Steel structures are light in weight and can be joined with bolts and other means of easy removal, making them ideal for structures that need to be disassembled or moved. One of the most representative is the Eiffel Tower in France. The Eiffel Tower is 324 meters high and weighs 10,000 tons. The construction of the iron tower fully embodies the advantages of steel structure engineering, construction time is shorter than expected, the cost is less than expected. The Eiffel Tower was supposed to be dismantled easily after the fair closed, so its designer gustav. Eiffel chose a steel frame with hollow out structure to facilitate disassembly. However, after the completion of the Eiffel Tower, it has become the most symbolic building in Paris and even the whole France, so the Eiffel Tower has remained until now, become the representative building of Paris.
