  Introduction When planning large-span buildings, choosing the right structural system is key. Here's how steel space frames , trusses , and rigid frames compare in terms of design flexibility, materials usage, construction speed, and cost. Strengths & Highlights Steel Space Frames – Outstanding load distribution across three dimensions—exceptional stability and seismic resilience. – Fast, modular assembly with factory-made precision (like Lego™) . – Supports stunning architectural forms with minimal internal columns. Space Trusses – Highly efficient at handling long spans using minimal material through axial load strategies. – Flexible in form—works well for pitched or curved designs. Rigid Frames – Reliable for clear spans under ~90 m, using standard moment connections. – Simple to fabricate and quick to erect; great for industrial or retail use. Practical Guidance Choose space frames if your project prioritizes architectural expression, large span, and o...

  1. When using small assembly units or members for direct assembly at high elevations, the sequence should ensure assembly accuracy and minimize cumulative errors. When using the cantilever method, the structure should first be assembled into a system capable of supporting its own weight, followed by gradual expansion. During the assembly process of space frame fabrication, the positions of reference axes, elevations, and deviations should be checked at all times, and corrections should be made promptly. 2. When erecting assembly scaffolding, the support points on the scaffolding should be located at the lower chord nodes. The scaffolding should be verified for its load-bearing capacity and stability, and load testing may be conducted as necessary to ensure safety and reliability. Measures should be taken under the scaffolding columns to prevent foundation settlement. 3. During the removal of the scaffolding, individual support points should be prevented from bearing concentrated...

III.Process control for the installation of bolted ball steel grid structures Bolted Spherical Grid Installation Process Before installing the space frame, installers must be familiar with all the members, ball types, dimensions, and their positions in the drawings. Any deformation of members caused during transportation, storage, or lifting must be corrected. All members and balls must be marked. During installation, they must be carefully checked against the drawings to ensure accuracy before installation. The installation of space frames primarily involves the connection between bolts and spheres. The friction surfaces of components must remain dry. High-strength bolts must be smoothly inserted into the sphere holes, with consistent insertion direction. They must be tightened in two stages, and each set of high-strength bolts must be fully tightened on the same day, with no bolts left untightened. Different installation processes must be adopted for different space frame configurat...

 Factors affecting the selection of space frames  mainly include space frame  production, installation methods, steel indicators, span size, stiffness requirements, plane shape, support conditions, and so on. space frame 5, the stiffness of the space frame   is much better than the plane roof frame, but between the various kinds of space frame , whether it is the horizontal stiffness or vertical stiffness, the difference is not small. A diagonally placed quadrangular cone space frame , is geometrically variable in itself, in the addition of edge members or a strong ring beam to ensure its geometric invariance. Generally speaking, the number of nodes and the number of rods is larger network frame, such as triangular cone network frame, hexagonal cone network frame, three-way network frame, and positive release quadrangular cone network frame, its stiffness is larger, on the contrary, such as diagonal release quadrangular cone network frame, tessellated quadrangular co...

Control points for acceptance of raw materials and finished products on-site ① Steel: should be based on the design requirements to specify the choice of steel grade, reference standard number, chemical composition, and physical properties of the index. Raw material suppliers should provide a complete quality assurance certificate and material test reports. The varieties, specifications, and performance of steel and steel castings should be in line with the current national product standards and design requirements, and the quality of imported steel should be in line with the requirements of design and contractual standards. Supervision shall require the steel structure contractor to submit quality certification documents, Chinese marks, and inspection reports to the supervisor for review, and the supervising engineer shall check all of them. ② Welding materials: the varieties, specifications and performance of welding materials shall meet the current national product standards and des...

The arched space frame   is a space structure formed by connecting multiple rods through nodes according to a certain space frame   form .   it has the advantages of small space force, light weight, high rigidity, and good seismic performance .   it can be used as a gymnasium, theater, exhibition Halls, waiting halls, stadium stand awnings, hangars, two-way large column spacing workshops and other building roofs. Due to the regular structural combination of the arch space frame , a large number of rods and nodes have the same shape and size, which is convenient for factory production and site installation. When the space frame   is assembled, the lower chord is usually welded first, so that the lower chord is arched upward due to shrinkage, and then the web and chord are welded. When using parts for general assembly, if all the rods are positioned and welded, it will easily cause the positioned welds to be pulled off during multi-faceted construction welding. Be...

    With the continuous development of the scientific and economic level, people pay more and more attention to the safety performance of buildings. The steel space frame   is beautiful in shape, light in weight, relatively small in steel consumption, convenient in construction and installation, and has good space carrying capacity. It has been widely used in roof construction projects. However, there are also certain problems in the construction of the steel space frame   structure. The steel space frame   structure has leakage and corrosion. If it is not handled properly, it will cause the steel space frame   structure to be unstable and the bearing strength will be weakened, which will affect the entire building. It is very important to do a good job in the damage, detection and treatment of steel space frame   roof construction.     Choosing a steel space frame   structure as a support in roof construction is a very practical constru...
