Node design of the cable arch structure and construction of the large span steel space truss.

Dome space rig. From the point of view of the engineers' experience and standard knowledge of the arched space truss structure, the connection of the nodes is mainly the connection of the soft cable and the cable, and the connection of the soft cable and the hard rod. From the point of view of the method of assembly of nodes and components, it is possible to divide the following points:

1) Connection of bracing cable and outer pressure ring: The outer pressure ring is generally a reinforced concrete ring beam, and the connection between the cable and the outer pressure ring is for anchoring of the cable to the ring of the reinforced concrete beam (external pressure ring) can be directly anchored with anchors;

2) Steel ball button and connection between cable and inner pull ring. Calculation of construction of large-span steel arched space truss. The inner pull ring is composed of a vertical bar and a cable ring and the inner pull ring is connected together. You can refer to the connection of the cable and the rod in the cable membrane structure, such as directly adding the ear cups;

3) Construction of the steel space truss of large span barbed cable arches, cross cables and longitudinal compression bars connecting between. The spinal cable is anchored to the node through the button plate; One end of the crossover cable and the vertical pressure bar is connected to the button. Considering that the cable is tensioned at this node, it is necessary to have a load-bearing surface of the jack. Hereafter, this node is referred to as the upper button;

4) Connection between ring cable, cross cable, and vertical bar. The top button loop cable is anchored by a pillow plate; One end of the crossover cable and the vertical bar is connected to the button via the gusset plate.

Design of bridge buttons and bolts associated with the cone head, telescope, truss rod of the dome space truss structure.

In the dome construction of a large span steel space truss supported with a steel ball button, the upper ends of the strut of each layer are hinged one way with the nodes of each layer corresponding to the single-layer mesh cover. and the bottom end is connected to the nodes of the next layer of the single-layer mesh sheath with radial cables, and the lower ends of the strut of the same layer The ring cables are connected together making the whole structure form. a complete structural system.

Large span steel space rig construction projects. In domestic technical cases, the badminton stadium of the Can Tho University of Technology, the gymnasium of the Military Zone 5 Sports Zone, Ministry of Defense, and the gymnasium of the Hanoi Sports Center, Hai Rooms ... all use a wire dome structure. Since the cables are usually arranged in a ring or ellipse shape, the corresponding nodes and chain structure are also somewhat different.

The structure of the buttons on the strut of the chain arch is similar to that of the chain structure and it should be made into one-way or two-way hinges; For the lower knot of the brace, two types of large span steel space truss construction structures are used depending on whether the cable body passes through this section, one is the lug type and the other is perforated. Due to the large force and complex structure of this button, it is usually fabricated by casting.

Prospects for the prestressed steel structure in the steel frame of the gymnasiums

The prestressed steel structure has over 50 years of development in the world, and in Vietnam; In my country, it has shown many of the characteristics and advantages of this type of structure, and the construction of large span steel space truss will become a new trend in the development of space truss structure. Therefore, the fact that prestressed steel structure in the future needs to be studied further in the following aspects:

The application of new structural materials will further promote the development of pre-stressed steel structures, so great attention should be paid to the study of new materials (such as stainless steel, aluminum alloys, etc.). membrane materials, ...), new processes. and new buttons for the prestressed steel structure.

Promote research on construction supervision and health monitoring of prestressed steel structures. During the construction of pre-stressed steel structures and the construction of large span steel space trusses, the changes in geometry and stress of critical sections of the structure should be monitored to provide an early warning of the safety of the structure.

Establishing a thorough theoretical system of prestressed steel structure and construction of large span steel space truss with engineering optimization methods. The design of a prestressed steel structure has a lot of uncertain variables, many of which need to be optimized to get the right design parameters and to create an excellent structural system.
