Steel structure engineering is a direct reflection of the current construction level of the construction industry. Therefore, whether from home or abroad, steel structure engineering has been developed at a high speed, and steel structure engineering has also attracted much attention. At present, in the field of steel structure engineering, there are mainly four types of structural models, including the following.


1 Cold formed thin-walled steel system. In this system, steel structural members are formed into C-shaped and Z-shaped members by cold bending of thin steel plates, which can be used alone or in combination. However, self tapping screws are used for the connection between components, which makes it difficult to ensure the node stiffness and has poor lateral force resistance. Generally, they are only used for 1-2 storey residential buildings or villas.


2 Frame system, this kind of steel structure project is set as a steel frame in both vertical and horizontal directions, and the doors and windows can be set flexibly to provide large bays, so it is widely used in multi-storey steel structure residence.


3 Frame support system. In this system, steel structures generally have multiple lateral force resisting systems, and beam column joints and column foot joints can be designed as articulated semi-rigid joints. The construction structure is simple, the foundation mainly bears axial force, and the shape is small.


4 Frame shear wall system, mainly used for low rise residential buildings. At present, it is widely used


These four kinds of steel structure systems also constitute the main structure system of steel structure engineering, which also plays an excellent role in promoting the development of steel structure engineering.
