What are the applications of higher-order hyperstatic structure in architecture?

图片
  The application of higher-order hyperstatic structure in construction is very wide, mainly because it has the characteristics of excess constraint, geometric invariance, complex force state, various structural forms, good stability and strong adjustment ability, etc., which can satisfy the high requirements of modern construction for structural stability, load carrying capacity and safety. The following are some specific application examples: I. Bridge engineering Bridges are one of the important fields for the application of high superstatic structures. Through the use of higher-order hyperstatic structure, the stability and bearing capacity of the bridge can be increased, so that it can withstand larger loads and deformation. III. large-span building Large-span buildings are also an important field for the application of high superstatic structures. With the continuous development of modern construction technology, people's demand for building space is getting bigger and bigger...

What are the requirements when choosing the glass for a dome?

图片
 The glass of the dome needs to consider a number of aspects of the selection of requirements to ensure that it meets the safety, functionality, aesthetics and energy efficiency of the building. The following is a detailed analysis of the requirements for the selection of glass for domes: dome 1. Safety requirements Strength and Impact Resistance: Dome glass must have high strength and impact resistance to resist external impacts such as wind, rain, snow, hail and possible accidental impact. Tempered and laminated glass are common choices because of their high strength and better load resistance. Blast resistance: For locations that require a high level of security, such as public places or buildings near earthquake zones, glass with blast resistance, such as laminated glass, should be used. Even when impacted by external forces, laminated glass can remain intact, avoiding the scattering of fragments, thus safeguarding the safety of people inside the building. 2.functional require...

What is the difference between a single-layer reticulated shell and a double-layerreticulated shell?

图片
  The differences between single-layer reticulated shells and double-layer reticulated shells are as follows: Structural Configuration   Single-layer reticulated shell: Composed of a single layer of members, with the members directly connected to form a grid structure . The node configuration is relatively simple, typically employing rigid connections that allow the members to bear not only axial forces but also bending moments and shear forces.   Double-layer reticulated shell: Consists of upper and lower parallel layers of members connected by web members, forming a truss-like structural system. The nodes are generally hinged, and the members primarily bear axial forces. Its configuration is relatively complex, requiring more members and nodes to ensure structural stability and load-bearing capacity. Structure Single-layer mesh shell: composed of one layer of rods, the rods are directly connected to form a mesh structure, the node structure is relatively simple, usually...

Suspension structures

 A suspension structure is a structural form that carries roof loads through a series of high-strength steel cables. Its main load-bearing member is the cables, which are usually steel cables made of high-strength steel wires. The roof of the suspension structure is generally light and thin, and its shape can be very flexible, able to realize the large span across. For example, in the roofs of some large conference centers or exhibition halls, the suspension structure can create unique shapes such as double-curved paraboloid or single-curved paraboloid, which make the building have a strong artistic influence. Suspension structures require a stable support structure to anchor the steel cables, usually using reinforced concrete columns or steel columns as support. And in order to ensure the stability of the structure, it is also necessary to set a certain amount of prestressing, so that the steel cables are in a tensioned state before they are subjected to loads. Scope of applicatio...

What is the typical service life of a steel space frame?

图片
Under ideal condition, the service life of steel structure space frame   can reach 50 - 80 years. This is estimated based on the performance of steel itself and reasonable design structure. If the steel structure space frame   is carefully designed, with full consideration of load, stress distribution and other factors, and used in normal environment, theoretically it can have a long service life. space frame Environmental fact ors 1.Corrosive environment: If the steel  space frame  is in a highly corrosive environment such as coastal area, near chemical factories, etc., the salt in the air and chemical gases (such as sulphur dioxide, hydrogen chloride, etc.) will accelerate the corrosion of the steel. In this environment, the service life of the  space frame  may be shortened to 20 - 30 years. For example, for steel structure net racks at the seashore, as the chlorine ions in seawater will have serious corrosive effect on the steel, obvious rust stains may...

What are the advantages of bolted ball-node mesh frame structures over other structures?

图片
space frame Convenient and fast installation: 70% of the workload of bolted ball space frame structure is prefabricated in the factory, and only bolting is required at the site, which is relatively simple to operate, and only a spanner is needed to tighten the bolts, without large construction equipment and complex on-site welding operations, which can effectively shorten the construction cycle and improve the construction efficiency. In contrast, the welded ball grid structure has a large amount of on-site welding workload, is greatly affected by weather conditions, and the welding process is complicated and the construction speed is slow. High construction safety: when installing the bolted ball grid structure on site, the overhead welding operation is reduced, which reduces the fire risk and the safety hazard of the construction personnel due to welding sparks, high temperature and so on. At the same time, the operation of bolted connection is relatively simple and requires relative...
