Principles of steel structure design

1 Stability principle

Development of building steel structure design. Attention should be paid to strict adherence to design principles. Steel structure design should be carried out according to the actual situation of the project. If the design concept does not conform to the construction concept of the project. It will inevitably affect the comprehensive quality of residential buildings. For steel structures. Attention should be paid to the principle of stability in construction. At present, most steel structures are designed on planar systems. The same goes for frame design. So when you're designing a plane structure. In order to avoid plane instability, reasonable arrangement of plane structure should be paid attention to to enhance the comprehensive stability of steel structure.

2 Consistency Principle

Steel structure design. You need to ensure consistent stability between the structure and components of the design. When you calculate the structure. Attention should be paid to its consistency with steel structure design. Nodes that transmit bending moments and nodes that do not need to be connected. This ensures the rigidity and flexibility of the steel structure. More convenient steel structure application. When a structural steel designer is doing design work. Care should be taken to accurately control the eccentricity of frame nodes. This is an important problem that can not be ignored in the design process. Cheese spoke of the stability of steel structures. The designers of steel structure should fully consider the actual situation of engineering construction. Flexible setting of steel structure strength.

There are many design points to pay attention to when designing steel structure. In order to ensure the stability of the later steel structure and the comprehensive quality of the building. In steel structure design and application. Special attention should be paid to the following points. First, the steel structure used in construction can be divided into low-rise and multi-storey. For low-rise buildings. Usually no more than 3 floors. It is mainly used for villas or low-rise houses. Multi-storey buildings are often used to build apartments. When the height exceeds 9 stories. Attention should be paid to the reinforcement of steel structure. It is generally not recommended that steel structures be higher than 12 storeys. Otherwise, the comprehensive stability of the building may be affected to some extent. Secondly, the seismic performance of steel structures is directly related to the regularity of structural layout. For residential buildings. The seismic performance of steel structure should be ensured when it is designed. This requires the layout of the steel structure to be unified. Elastic design is an important part of steel structure design. In order to ensure the comprehensive quality of elastic design of steel structure, in the design work. In the design of steel structure, attention should be paid to the accurate calculation of the elastic-plastic layer displacement so that the structure layout can meet the actual needs of engineering construction. In the plane design of steel structure, regularity and symmetry of structure should be guaranteed as far as possible to make the force of steel structure more uniform. If the plane shape of steel structure is irregular, such as L shape or F shape, it is easy to affect the comprehensive stability of steel structure. Especially for the supported shear wall structure, once the asymmetric or uneven structure, it is easy to cause the displacement of the shear wall structure. In general, if the elastic horizontal large displacement of a floor exceeds 1.2 times of the horizontal displacement of the center of mass, the plane structure is considered irregular and should be adjusted in time. In the space combined with the steel structure design, we should highlight the focus and center, and the architectural modeling should be simple, so that there is unity in the change, there is change in the unity, so that our steel structure workshop is more artistic.
