How long is the service life of steel structure project, the key is here

Most people have the psychology that as long as it belongs to me, I hope that it will live as long as possible. How can it serve us for a long time? The key is that we need to understand it clearly, such as its advantages, design intent, and basic design methods.

As we all know, the advantages of steel structure engineering are obvious, and it can be involved in a wide range of industrial and commercial and civil buildings, etc. For example, industrial plants, residential buildings, urban busy areas with limited land, etc.

From the design type, there are door steel structures, and the frame is mostly H-shaped steel composite frame steel. The rolling slab steel plate is often added with reinforced concrete slab, and the thickness is generally not less than 150 mm. If steel beam is used with steel and concrete slab, it is called MST composite beam. As long as the calculation is correct, reinforcement is reasonable, bolts are reliable, and steel beam used for floor and roof can save about 20%. Check the stability of the steel beam. Compared with concrete construction, steel structure construction greatly saves construction time and construction is not affected by seasons.

The basic design method of steel structure engineering: the foundation requires high, the depth is 1.5m-3m, and the composite ground beam is complementary.

In addition, the steel structure project has flexible layout and high house price. The interior partition wall is used for small bearing capacity, and can be flexibly designed for indoor layout, such as open space, layering, etc; The wall thickness is about 1/2 of the traditional structure, and the internal area increases. More than 10%; Slab has no main beam, and the floor height increases by more than 200mm. Increase the use area of residential space and reduce the construction waste and environmental pollution; The construction materials can be reused, and the steel structure raw materials drive the development of the domestic real estate, building materials and hardware industry; The steel structure engineering adopts composite wall and floor, various equipment, and pipes can be embedded in it. Intelligent technology equipment such as anti-theft, visual intercom system, fresh air ventilation system and other intelligent technology equipment can be reasonably combined with the shell products. At the same time, it also has good seismic performance, easy to modify, flexible and convenient in use, giving people a comfortable feeling.

It is 30% to 50% lighter than that of steel concrete structure engineering; Moreover, the steel structure has a small section, a wall thickness of about 1/2 of the traditional structure, an increase of more than 10% of the internal use area, a novel appearance and generous appearance, and a comprehensive service life of 70-100 years.
