Difference between steel frame grid structural and steel structure
The steel structure has good stability and can meet buildings of various shapes, such as various large venues, airports, high-speed railways, etc. Steel frame mesh structure is a kind of steel construction, which belongs to the same type. However, the difference between steel frame network structural and its structure lies in the connection mode, the use of structural materials and structural form, which are different from structural system.
From the connection mode of steel structure:
1. Nodes are considered as rigid contact, and fusion is usually used.
2. The nodes of grid structural are regarded as hinges, which are usually connected by bolts.
From the use and form of materials:
1. Start with steel structure materials.
2. From the perspective of structural form, the grid can include steel grid, aluminum alloy grid, etc. However, in practical application, except for steel grid, steel grid is mostly composed of steel frame, steel portal frame and other forms.
From the perspective of structural system:
1. The steel grid is a spatial structure system, and the overall stress and spatial deformation shall be considered in the calculation.
2. Steel structure is similar to plane steel truss and belongs to unidirectional stress structure. As long as the in-plane strength and stability are calculated, the out of plane stability mainly depends on the strut and tie rod.
3. Compared with the steel grid structure, its structure eliminates the longitudinal members of the bottom chord and the spherical joints of the grid. The truss structure is developed on the basis of steel truss structure. Compared with grid structure, truss structure is more economical.
At the same time, its structural processing plant shall have rich experience in bending reinforcement processing, especially steel pipe processing and welding quality control.
To sum up, the difference between steel frame grid structural and steel structure can make us use them more clearly through the above introduction. So as to effectively give play to the use efficiency and reduce various problems caused by improper selection.
