Description

Technical Field

[0001] The utility model relates to a steel structure factory building with an earthquake-proof structure, belonging to the technical field of steel structure buildings. Background Art

[0002] With advances in building materials and construction technology, steel structures have flourished. Large bridges, skyscrapers, and stadiums have all replaced traditional reinforced concrete structures with steel structures. These structures not only offer a wide variety of designs and a more aesthetically pleasing appearance, but also reduce construction costs and shorten construction cycles. In addition to residential buildings, steel-structured factories are also becoming increasingly popular in industrial enterprises, with new factories primarily constructed using steel structures. Steel-structured factories primarily consist of load-bearing components made of steel, including foundations, columns, beams, and connecting members. These buildings can be categorized as either light or heavy steel structures. The columns, beams, and connecting members of steel-structured factories are typically made of steel structural members. For small factories, steel structural members can be constructed directly from steel sections, such as I-beams, channels, square steel pipes, and round steel pipes. However, due to manufacturing processes, these sections are often limited in size. Larger factories, on the other hand, typically use steel sections welded to steel plates to form a single steel plate frame.

[0003] Steel-structured factories offer significant advantages, including light weight, high strength, large spans, short construction periods, and low investment costs. However, they also have disadvantages, such as poor stability, poor seismic performance, and prone to collapse. Overall, these advantages far outweigh the disadvantages, making them the future development direction for industrial factories. Currently, in areas without the threat of earthquakes, typical steel-structured factories lack specialized seismic design, relying instead on the inherent connection structure of the steel components for earthquake protection. However, in areas prone to frequent earthquakes, steel-structured factories must be seismically designed to prevent tilting or collapse during an earthquake, ensuring the safety of equipment and personnel within. Therefore, designing seismic-resistant steel-structured factories is essential in earthquake-prone areas. Utility Model Content
