  The high speed railway station has a novel shape, and the structure above the ground adopts steel structure and the overall scheme of steel structure + space  frame is adopted. In order to realize the design concept of "displaying the natural beauty of the structure", the structural main station adopts the construction and bridge integration structure system according to the requirements of the building facade and the interior decoration effect. The structural system of "A column +Y column + straight column supported catenary steel truss roof "is designed. The tilt Angle of the west leg of pillar A is consistent with the elevation Angle of the building, which cleverly integrates the structural members into the building facade and provides effective lateral force and vertical support for the structural system. Y-pillar provides a more spacious and comfortable space for the waiting hall, enriches the interior visual effect, and reduces the structural span of the

 Cold-formed steel members have the advantages of light weight, high strength, easy prefabrication and mass production, fast installation and recyclable. The cold-formed steel structure system is mainly composed of wall system, floor system and roof system. Through theoretical analysis and experimental research, the cold-formed steel structural system is studied in depth.  The research direction covers the mechanical performance of cold-formed thin-wall steel basic members and composite members, the lateral resistance performance of composite walls, the bearing capacity, stiffness and comfort of composite floors, and the seismic performance of the whole building. The relevant research results are as follows: 1) The half-energy method is used to deeply study the related effects of plate group buckling, and the design method of effective width to thickness ratio of edge stiffened plates is established; The failure characteristics and mechanical properties of cold-formed thin-wall steel

  In the construction industry, space frame  engineering as a form of building structure, has been widely used. This engineering approach provides excellent stability and safety for buildings through the use of high-strength materials and scientific structural design. space frame  engineering is a kind of construction technology based on space frame  structure . It uses materials such as high-strength steel and aluminum alloy, which are processed and assembled to form a stable and safe building structure. This kind of structure has the advantages of light weight, strong bearing capacity and good stability, and is widely used in industrial buildings and other fields. First of all, the space frame  engineering has excellent stability and safety. This structural form is able to evenly distribute the load, giving the building excellent stability under various external pressures. The space frame  engineering also has good seismic performance, which can effectively reduce the impact of eart

  As a kind of steel structure , the space frame   is an essential part of modern architecture, which is used to support the heavy roof and facade. With the rapid development of architectural design, more and more space frame   schemes are available. However, how to choose the right space frame   installation scheme? What factors need to be considered? 1. Material selection: The selection of space frame   material is the most critical step in the installation of space frame , different materials have different advantages and disadvantages, need to be selected according to the project needs, construction environment and building form and other factors. (1) Steel: Steel, as a commonly used space frame   material, has superior stability and load-bearing capacity. Steel can complete a variety of large-span curtain wall, glass curtain wall, ceiling and other buildings, widely used in commercial complexes, large high-end hotels, exhibition centers, airport terminals and other types of buildi

  The load of the space structure is uniformly transferred. When bearing the load, the space frame   structure can transfer the load to all the members, which bear the load, and distribute the load evenly to the support of the space structure. The construction is fast and convenient, and the space frame  structure is an assemblable component, which greatly reduces the difficulty of construction and shortens the construction period. Construction equipment can be installed in the space frame  structure itself, reducing the installation of auxiliary construction trouble. The structure has high strength and large load. The   space frame  structure has more fixed ends, and in general, even if the occasional damage to the components will not necessarily cause the destruction of the entire structure. Because the space space frame  structure mostly has a fixed regular pattern, it can give people a sense of impact visually. The large-span space structure has high installation efficiency and obv

  space frame  processing for the space frame  production of each process has extremely strict requirements, from the space frame  design you need to understand the structural characteristics of the steel structure of the space frame  to carry out, its later space frame  processing production, are required for the characteristics of the space frame  steel structure to strictly control the control, then for the characteristics of the space frame  steel structure how much do you know? Here we introduce the main characteristics of steel structure space frame . 1, the material is uniform, more in line with the mechanical calculation assumed just because of the scientific control of smelting and rolling process, its internal structure is more uniform, close to a variety of same-sex, in line with the ideal elastic-plastic body. Therefore, the uncertainty of the calculation is small, and the calculation results are more reliable. 2, plasticity, toughness good plasticity: the steel structure

As a form of  steel structure , with the rapid development of the construction industry, space frame  processing as an important processing technology, its quality control and quality assurance methods are of great significance for improving project quality and reducing project costs. This paper will introduce the importance of quality control and quality assurance methods, the specific methods and the relationship between them, and put forward some suggestions.   I. Introduction space frame  processing is a process in which materials are made into products with certain shapes and specifications by cutting, grinding, splicing and other technological means. space frame  processing is widely used in construction and other fields, and its quality control and quality assurance methods directly affect the quality, safety and reliability of products. Therefore, for space frame  processing enterprises, it is essential to establish strict quality control and quality assurance methods. II. Qual

  space frame   use instructions and later maintenance, the following three possible risks and maintenance. 1. Fire hazard The temperature resistance of steel is poor, and the performance of many light steel structures varies with the temperature rise and fall, when the temperature reaches 430-540 ° C, the yield point, tensile strength and elastic modulus of steel will drop sharply and lose the carrying capacity. The necessary maintenance of steel structure with refractory materials is an important lesson of steel structure research, vertical collapse in situ, forming "flat cake" effect. The direct cause of the accident, which shocked the world, was the fire. Of course, to exclude the occurrence of such events, there are also aspects involved in this case. Fire-resistant paint or sprinkler systems are ineffective. 2. Potential instability ① Global instability and local instability. Most of the global instability is caused by local instability, when the slenderness ratio of th
