It consists of beams, columns, trusses and other components made of steel plates or sectional steel. Each component is connected by welding, bolting, riveting and other methods. It is widely used in super high-rise buildings, large-span buildings, bridges, tower mast structures, removable structures and structures that require light weight.

Steel Structure Products

The steel structure is mainly made of steel, which is one of the main types of building structures. Steel is characterized by high strength, light weight, good overall rigidity and strong deformation ability, so it is particularly suitable for the construction of large-span, super-high and super-heavy buildings. Steel structures are components such as steel beams, steel columns, steel trusses, etc., made of sectional steel and steel plates; structures with welds, bolts or rivets are used between each component or part.

The steel structure has developed vigorously in the public construction field. It is often used in factories and multi-storey houses, and has expanded to super high-rise buildings, large-span convention and exhibition centers, sports venues, large-scale transportation buildings, ports, docks, roads and bridges, fire stations, subways, high-speed rail and other places. At present, more than 1,000 super high-rise steel structures have been built and have been built, and the steel structure is developing in a higher, wider and lighter direction.

CHARACTERISTICS OF GRID STRUCTURE

Grid Structure Characteristics

The self-weight of the grid structure is light, the amount of steel used is saved, and the application range is wide, which is suitable for both medium and small spans, as well as large-span houses. The basic units that make up the steel grid structure are triangular cones, triangles, squares, truncated tetragonal cones, etc. These basic units can be combined into planar triangles, quadrangles, hexagons, circles, or any other shapes. It has the advantages of space stress, light weight, large stiffness, and good seismic resistance;It can be used as a roof for buildings such as stadiums, movie theaters, exhibition halls, waiting halls, stadium stand canopies, hangars, two-way large column steel grid structures, etc.

This new style structure method relies on the force of the steel body itself. A steel pillar is connected together by a bolt ball and staggered to support each other, and the net is formed into a roof space with different shapes.

Vigorously developing steel structure buildings is an important measure to promote the construction industry to achieve "carbon peak and carbon neutrality", and an important driving force for industrial transformation and upgrading and high-quality development. As one of the high-performance structural systems, high-strength steel structures have attracted much attention from researchers and the engineering community in recent years.Compared with conventional Q235 and Q355 steels, high-strength steels have higher unit mass strength. The use of high-strength steels instead of conventional steels in structural systems can reduce the cross-sectional size of components, reduce the self-weight of steel structures and the load of foundation parts, thereby effectively reducing the amount of steel used and reducing the carbon emissions of such structural systems. This is in line with the development strategy of China's new round of green, low-carbon and new-type building industrialization.However, welding is one of the main forms of high-strength steel connections. The high temperature of welding may cause significant changes in the microstructure and mechanical properties of high-strength steel, resulting in the reduction of strength and ductility in the heat-affected zone and the reduction of toughness, which restricts the application of high-strength steel structures in steel structure buildings.

According to the stress function, position and construction form, it can be divided into three categories: main bearing member, secondary member, enclosure and connecting member, covering from the main body skeletonTo all components of the detailed structure, the main load-bearing member (core stress skeleton) bears the vertical load, horizontal load, bending moment and shear force of the structure, which is the "skeleton" of the steel structure, which determines the overall strength, stiffness and stability.
• Column members (vertical load-bearing, pressure-based) directly transfer floor and roof loads to the foundation, which are vertical core stress members. Solid web pillar: It is welded by H-shaped steel, I-beam, and box-shaped steel plate. It has high stiffness and high bearing capacity, and is mostly used in high-rise, large-span factory buildings, and frame structures. Lattice column: It is composed of angle steel/channel steel + decorative strip/decorative plate, which is light in weight and controllable in length and slim ratio, and is mostly used for plant row columns, towers and brackets. Shaped columns: L-shaped, T-shaped, cross-shaped columns, mostly used for residential steel structures, taking into account load-bearing and space utilization.
• The beam components (mainly transverse load-bearing and bending) bear the load of the floor, roof, and wall, and transmit the force to the column or truss, which is divided into horizontal main beams and secondary beams. Solid web beams: H-shaped steel beams, welded I-beams, and box beams are the most commonly used, and are suitable for factory buildings, frames, and floor systems. Truss beam: A lattice type bending member composed of steel bars, light in weight and large in span, used for large-span roofs, bridges, and trestles. Crane girder:Special bending member, bearing the vertical and horizontal braking force of the crane, adopting special H-shaped steel or welded combined section for industrial plant.
• The truss member (long-span bending/bending member) consists of an upper chord, a lower chord, a web rod (vertical rod, inclined rod), and is bent as a whole. Most of the internal rods are axial tension and compression, which is suitable for large-span roofs, grids, trestles, and towers. Chord: Withstand axial tension/pressure; Web: Connect the upper and lower chords, transfer shear force, and stabilize the truss.

Grid Structure Advantages

Main Grid Structure Products

With the rapid development of China's steel structure industry, steel grid structures have been gradually promoted and used in various buildings such as airports, high-speed rail stations, stadiums, and thermal thermal power plants due to their novel shape, short construction periods, and energy-saving and carbon reduction. At present, there are many studies on the installation technology of steel grid structures in China. For ultra-large-span steel structure mesh frames, the cumulative push-slip construction technology is proposed, and the overall jacking construction of the assembly is connected. At the same time, the numerical simulation and optimization analysis of the special-shaped hyperboloid steel structure roof space based on the Building Information Model (BIM) is carried out.Construction simulation, collision inspection and mechanical software verification methods based on BIM technology for steel grid structures; real-time monitoring and correction of the mesh frame assembly process with digital monitoring equipment, point cloud scanners, total stations and other tools, and real-time review of on-site monitoring data; large-span steel grid structure lifting and positioning technology, steel structure mesh frame welding support technology, deformation monitoring technology for mesh frame structural buildings, and network laying laser ranging technology.The construction management system ensures the installation progress and operation safety of the mesh frame, shortens the construction period and reduces the cost, which can provide an important basis for the installation and construction of the same type of steel grid structure.

CONSTRUCTION PROCESS OF STEEL STRUCTURE ENGINEERING

Steel Structure Grid

The steel structure grid frame is a multiple ultra-stable space structure, which is precisely due to the multiple ultra-stable characteristics of the structure and its unique degree of flexibility compared to other structures. Structural internal forces are usually calculated using the matrix displacement method. The matrix intermediate depends on the project situation, and the matrix intermediate of simple projects should reach tens of thousands of times. The matrix intervals of more complex projects are difficult to count. Even if the Gaussian iteration method is used by the computer, the calculation will take several hours at a time.Because of the large workload of structural internal force calculation and the high difficulty of construction drawing design, the popularization and use of the grid structure was greatly restricted before the degree of computer-aided design was completed.
