The importance of steel structure design in steel structure building

Because the stability of the steel structure is better, the service life is long, the internal structure is firm and so on, these characteristics make its utilization rate higher and higher. With the improvement of living standard, people's requirements for building structure have also been improved. Therefore, there are more designs for steel structure design, but there are also some problems.

First, the importance of steel structure design in building structure design analysis

In the actual process of building structure design, steel structure design is an important part. From the nature of architectural structure design, steel structure design not only has geometric components, but also reflects some technical factors.

However, in this design project, if any of the design links are wrong, it may affect the quality of the later installation, and even affect the overall stability. In addition, designers need to switch the actual, understand the structural requirements, structural stress characteristics and other aspects of the requirements.

Main construction method of steel structure building

1. For steel structure processing and production of box columns, we generally use steel plates. For the box and raft foundation plate, we from the structural point of view, if you can lift the plate, can adjust the edge span bottom bar, especially when the bottom bar length layout, not because of the edge span reinforcement and increase the whole bottom bar length, saving; After lifting the plate, the additional stress of the foundation can be reduced. When the foundation form is on the natural foundation and other artificial foundation, the natural foundation may be adopted.

2. Steel structure installation. The floor of steel structure building is generally composed of laminated laminated laminated steel plate and cast-in-place reinforced concrete. During the installation of steel structure profile steel plate, the process of the interworking process: the main body of the steel structure is accepted and qualified -- setting up the support truss -- installation welding of profile steel plate -- bolt welding -- sealing plate welding -- construction of equipment pipelines and circuit lines after inspection, reinforcement binding -- concrete pouring.

3. Concrete construction of steel structure buildings. In the steel structure building project, the concrete part construction mainly has two aspects: one aspect is the cast-in-place concrete floor; Another aspect is the core cylinder wall. Concrete is mainly transported vertically through concrete pumps. According to the structural characteristics of the project, the floor formwork support scheme uses the lower flange of H-beam to support the small H-shaped steel, and the bamboo plate and steel bar are placed on it. The method of pouring concrete inside the box column is to push the concrete into the box column from bottom to top with the help of pump pressure, that is, the jacking method.

The strategy of steel structure design in building structure design

1. In accordance with the general principles of steel structure design, to.. The stability of the steel structure also needs to meet the following conditions: the layout of the steel structure needs to be considered from the stability requirements of the system and each component. At present, most of the steel structure is designed according to the plane system, such as truss and frame,.. The plane structure does not appear out of plane instability, so the plane stability calculation of the plane structural members should be consistent with the structure layout, such as adding necessary support members.

2. When designing steel structure in building structure design, designers should fully consider the problem of corrosion prevention. This is because the steel structure in the actual use process, in order to.. The overall aesthetic of the exterior of the building, the construction personnel will usually spray zinc or aluminum. However, because zinc and aluminum are chemical substances with strong corrosion, in the spraying process, it is bound to cause some damage to the steel structure, which needs to apply a layer of anti-corrosion structure outside the steel structure, in order to protect the steel from corrosion.

3. Fire prevention should be considered in the design process. Fire protection of steel structure has a variety of methods, these methods are mainly: steel structure fire coating protection, fire protection board, concrete fire protection, flexible coil fire protection, fire-resistant steel, water cooling in the structure. When choosing the fire prevention design of steel structure, the following factors should be considered: the part of the steel structure, the nature of the component to be protected; The increased weight and occupied space of the steel structure after taking protective measures; The reliability of protective materials; Construction difficulty and economy.
