The space frame structure is generally a high-order hyperstatically indeterminate structure, which can better withstand concentrated loads, dynamic loads and asymmetric loads, and has good seismic performance. The space frame structure can adapt to the requirements of public buildings and factory buildings with different spans and different supporting conditions, and can also adapt to different building planes and their combinations.
How to arrange the support of the steel structure space frame? The support of the space frame generally includes peripheral support, point support, etc. Peripheral support is the most commonly used support form at present. It rests the peripheral nodes of the space frame on columns or beams; point support means that the space frame is placed on independent columns, and the columns have no connection with other structures.
In large public buildings, especially long span space structures, such as stadiums, convention centers, theaters, etc., some lighting, sound and other stage control facilities will be placed on the roof structure. If these facilities need maintenance, the staff will How to get to these places? Therefore, when we are doing structural design, we will consider arranging some passages for staff to walk at high altitudes - "catwalk".
Welding of steel structure plant is a method of linking the components of steel structure plant, so attention must be paid to the welding, if it is not up to the standard, it will affect the stability of the steel structure plant itself, and it is likely to lead to the steel structure plant itself is not up to the standard of the degree of solidity, so as to produce the collapse, which will result in the loss of property and threaten the life of the workers in the plant.
The stability of the space frame structure is also an advantage of the space frame structure compared with other structures. As we all know, triangles are very stable in geometry, but the stability of rhombuses and squares will be worse, while the space frame structure From a plane point of view, it is a combination of multiple triangles.
