How many systems are there in steel structure engineering buildings?
Steel structure engineering is the direct embodiment of the building level of the current construction industry. Therefore, steel structure buildings have developed rapidly at home and abroad, and attracted much attention. At present, there are four structural models in the steel structure engineering industry. The details are as follows:
1. Cold formed thin-walled steel system
Under this system, the members of steel structure engineering can be cold-formed into C-shaped and Z-shaped members with thin steel plates, which can be used alone or in combination. However, the stiffness of self tapping screw joints is not easy to ensure, and the lateral resistance of connection between components is poor, which is generally only used for 1~2 storey houses or villas.
2. Frame system
This kind of steel structure project is equipped with steel frames horizontally and longitudinally, and the windows and doors can be set flexibly, which can provide greater depth. Therefore, it is widely used in multi-storey steel structure residential buildings.
3. Frame support system
Under this system, steel structure buildings generally adopt a variety of lateral resistance systems. Beam column joints and column foot joints can be designed as fixed connections, semi-rigid connections, simple construction structure, key bearing axial force of the foundation, and small size.
4. Frame column system
This kind of steel structure project is mainly used for low rise residence, and has been widely used at present.
