The steel structure space frame is made based on what principle

Principle of steel structure space frame manufacturing: When the span of the space frame is large, the height of the space frame also increases accordingly. Therefore, for the large span structure, the space of the fasting mesh layer can be used as a separate building layer. This type of empty gap is both a structure layer and a building layer. At the same time, the space frame layer has a large leap capacity, which makes the new structure system with large and small spaces crossing building functions. It overcome some of the buildings at the bottom or top of the building in the past or the top floor of large spaces, and is especially suitable for large span and high -rise buildings.

The new type of space structure system has been conducted systematically from the aspects of the composition of the steel structure space frame system, static characteristics, and seismic performance. The composition of different structures makes the structure have different force characteristics. Based on the structure of the ordinary jump -stroke airbound rack, this article analyzes and studies different types of jumping space frame space frame structures such as inclined abdominal rods, mesh space frame unproof, and space frame branches of mesh shelf. Internal force distribution and deformation of vertical loads and horizontal loads. At the same time, the structural internal force and deformation changes were further analyzed by the participation of the floor of the floor and exerting prestress; the conclusions of the analysis and calculation provided theoretical reference for the selection and design of the structure in engineering design.

After studying the stress characteristics of the structure under the action of vertical loads, this article is based on the layering method of the cross -beam system and the multi -layer framework of the cross beam system of cutting and deformation. The simplified analysis method of the jumping layer of the empty stomach space frame has made great improvement on the simplified methods proposed by some scholars in the past. This method has a high calculation accuracy and is particularly suitable for the preliminary design of the structure. For the structure of the jumping layer, the concept is generally believed that the resistance and collapse of the structural system under the action of strong earthquakes are poor. This article reveals the effects of the changes in the rigidity of the space frame of the space frame of the space frame and the stiffness of the supporting structure on the structural autobiography frequency and vibration type through the analysis of the self -vibration characteristics of different types of an empty -stroke space frame structure on different types of jumping.

At the same time, this article studies the seismic resistance performance of one dimension in the three directions of the earthquake in one dimension in the three directions of the earthquake, and the structure of the structure of the structure under the action of the earthquake and the deformation of the earthquake.
