Weld-Free and Worry-Free: Redefining Structural Efficiency in High-Seismic Regions

-
图片
 For contractors weary of labor-intensive, time-consuming structural installations—especially in high-seismic zones— bolted steel framing offers a solution that radically redefines safety standards. Its core advantage? A design that guarantees ease of assembly without sacrificing seismic performance, streamlining on-site workflows while meeting every compliance requirement. The days of project delays caused by on-site welding, tedious alignments, or bulky reinforcement are over. Bolted steel components are prefabricated, precision-cut, and pre-drilled, ready for assembly straight off the truck. The intuitive bolting system requires no specialized skills for installation, allowing crews to erect frames with rapid precision, significantly cutting down installation time compared to rigid structures like concrete. No more worrying about mismatched parts or labor-heavy phases—this system is built for high-speed execution, even under the toughest site conditions. But simplicity doesn’t ...

Structural Characteristics of Steel Tube Joist

-

  As a structural engineer, I would look at the following aspects of analysing a steel tube joist : I. Structural characteristics: 1. Simple structure: Pipe truss structure is connected by several sets of pipe rods and nodes, which does not need a large number of parts, so the structure is very simple. This design not only makes installation and dismantling faster and more convenient, but also reduces the manufacturing cost. 2. Light weight: Pipe trusses are made of lightweight materials and the overall weight is light. This helps to reduce the load of the building itself and improve the load-bearing capacity of the building. 3. High Strength: The tube truss structure is made of high strength materials such as steel pipe, so the whole structure has high load bearing capacity and wind resistance. It can withstand larger loads and external impacts to ensure the stability and safety of the building. 4. Good anti-seismic performance: Due to the stability and flexibility of tube truss ...

Application of space frames to hangars

-

To date, space frame structures have been widely used in China, with application scenarios including but not limited to: industrial plants, coal storage structures, hangars, airport terminals, high speed rail stations and large stadiums. 💚💚💚 Hangars require a large span and space sufficient for aircraft parking, but also a certain load-bearing capacity to withstand the loads brought by the equipment during aircraft maintenance. In order to increase the load-bearing capacity, the construction of hangar structures has been accompanied by improvements and innovations to the traditional two-storey space frame structure. For example, the four-bay hangar at Beijing Capital Airport, built in 1996, has a three-storey space frame structure with dimensions of (153+153)m × 90 m. The hangar of China Southern Airlines at Beijing Daxing International Airport, built in 2019, has a W-shaped truss + space frame structure system with a span of 222 m at the opening side of the gate. hangar
