spatial structure that is formed through interconnecting the nodes of multiple truss members in a certain form of grid configuration. it has the advantages of space force, light weight, large rigidity and good seismic performance, and can be used as the roof of large span arch sheds, gymnasiums, theaters, exhibition halls, waiting halls, stadium canopy awnings, hangars, bi-directional large column spacing workshops and other buildings. (the picture shows a typical grid structure) the truss member cross-section of the grid structure should be calculated and determined according to the strength and stability. to reduce the calculated length of the compression rod and to increase its stability, additional measures such as sub-rod and support rod can be used. plate-type grid made of steel and double shell-type grid nodes are mainly in three forms, namely cross-plate joints, welded hollow spherical joints and bolt-sphere joints. cross plate joints are used for grid structure of steel truss members, the connection of the truss member and the node plates uses welding or high-strength bolts. hollow spherical joints and bolt-sphere joints apply to the grid structure of steel bars. single-layer shell-type grid nodes should be able to withstand bending internal forces, under normal circumstances, the node's steel consumption accounts 15 ~ 20% of the amount of steel used for the entire steel grid structure.

introduction to high-rise steel structure:
high-rise building refers to residential buildings with more than 20 floors of and public buildings and integrated buildings with more than 24 meters of total height, steel structure has high strength and compared to concrete structure the steel column cross-sectional area is small which increases the effective usable area of the building, and can be used to build tall, heavy-duty buildings with heavy loads, compared to the column cross-sectional area of general high-rise steel structure, nearly half of column cross-sectional area of high-rise concrete structure is reduced. steel structure building is light in weight, therefore, high-rise building using steel structure is a new type of energy-saving building system, known as the "green building" of the 21st century, which is an energy-saving and environment-friendly, reusable building structure.

introduction to pipe truss and bridge structure:
pipe truss structure and truss structure refer to the lattice structure where truss members are interconnected at the ends, the pipe truss truss refers to the structure in which the rods are all circular bars. in most cases, the rods in the pipe truss are subject to axial tension or pressure only, and the stress is evenly distributed on the cross-section so as to give full play to the role of materials. these features make the truss structure have economical materials and a small self-weight. easy to form a variety of shapes to suit different uses, for example, it can be made into simple truss, arch, frame and tower, thus truss structure has been widely used in many of today's large-span venues and buildings, such as convention centers, stadiums or other large public buildings. steel bridges are the bridges built of steel structure, the general amount of steel used in this bridge amounted to 50% or more is called "large steel bridge". its main body is made of alloy steel, which is assembled and welded after the production of parts and components. it is a new type of bridge construction mode that is fashionable at present. advantages of steel structure bridge: the plasticity and toughness of steel are good so that the seismic performance of steel structure bridge is outstanding; the construction period is short; the quality of steel bridge is easy to guarantee; the steel structure bridge is easy to be reconstructed during the use, such as strengthening, height addition and road widening, which the change is relatively easy and flexible; steel structure is environmentally friendly products; the pipeline is easy to arrange.

introduction to frame steel structure:
the main advantages of frame structure: flexible space division, light weight, saving material; has the flexibility to cooperate with the layout of the building plane, which will help arrange the building structure asking for greater space; the beam and column components of the frame steel are easy to standardize and finalize, which facilitates the assembly of the integral structure to shorten the construction period. when the cast-in-place concrete frame is used, the structure indicates good integrity and rigidity, if well designed and treated, it can achieve better seismic effect, and the beams or columns can be casted into a variety of required cross-sectional shapes. frame steel structure is commonly used in large-span public buildings, multi-storey industrial plants and some special-purpose buildings, such as theaters, shopping malls, stadiums, railway stations, exhibition halls, shipyards, hangars, parking lots, light industrial workshops, etc.

introduction to ordinary steel structure:
lightweight steel structure (ordinary steel structure) is a young and vital steel structure system that has been widely used in general industrial, agricultural, commercial and service buildings, such as office buildings, villas, warehouses, stadiums, entertainment and tourism buildings and low, multi-storey residential buildings and other fields, it can also be used for the storey-addition, reconstruction, reinforcement of old houses and buildings in areas lack of building materials, transport inconvenience, and tight schedule and removable buildings, which is very much favored by the owners.
features:
1) using effective lightweight thin-walled section, with light weight, high intensity and small footprint.
2) automatic, continuous and high-precision production for components and parts, the product specifications are in series, finalized, and in system. the size of each part is accurate.
3) structural design, detail design, computer simulation installation, factory manufacturing, site installation, etc. are conducted in less time difference. kong
4) dry construction method is not wet operated above the foundation, the interior decoration and so on are easy to put in place once for all. after galvanized and coated, the section is beautiful and anticorrosive, conducive to reducing the cost of enclosure and decoration.
5) facilitate the expansion of column space and provide greater separation space, which can reduce the storey height and increase the building area (the usable area of the residence up to 92%). with obvious advantages in the storey-addition, transformation, reinforcement.
6) the wide range of applications of new wall materials, extensive use of daylighting band, and good ventilation.
