What are steel structure workshop and frame structure workshop?

There are many forms of workshops, including brick and tile cement workshops in the 1970s and 1980s, and steel structure workshops and frame structure workshops in the new era. But now there are few concrete structure workshops. In today’s Industrial Park, the factory workshops are basically steel structure workshops. So what are the differences between frame structure workshop and steel structure workshop, and which is better? For this comparison, the answer is not the same. Let me give you a brief introduction.

about construction cost

The frame structure is generally a kind of building structure composed of beams and columns with load-bearing capacity, plus some lightweight plates for partition walls. The beams and columns are generally cast by reinforced concrete. The cost of steel structure workshop is lower than that of frame structure workshop. If both functions are OK, it is recommended to select steel structure workshop to save cost. Of course, if it is a steel-concrete structure, the construction cost will be relatively high.

about construction period

The construction speed of steel structure workshop is fast and the construction period is short. The production cycle of components is determined according to the specific capacity of the construction unit. It depends on the production capacity of the steel structure company. If the output is large, the completion speed of steel structure construction will be accelerated.

about impact resistance

The advantage of steel structure workshop is good seismic performance. The occurrence of earthquake disasters will cause great damage to people’s life and property safety. The steel structure has good ductility, which can offset the energy consumption of seismic waves. According to the calculation, the strength of the steel structure is 8 times that of the concrete, and its density is only 3.2 times that of the concrete. Therefore, for the same bearing capacity requirements, the steel members have light weight and high section utilization, so it has a good effect on earthquake resistance.

about corrosion resistance

Corrosion resistance is the short board of steel structure buildings. If the plant needs to be built in a place with serious corrosion, it is recommended to give priority to the frame structure plant.

about fire prevention

The fire resistance of steel structure is one of the few shortcomings in steel structure buildings. Therefore, if you need a plant with strong fire resistance, you should choose a frame structure or choose to improve the fire resistance of steel structure components.

about bearing capacity

For multi-storey workshop, the workshop with frame structure has high bearing capacity. If the workshop floor needs to install heavy mechanical equipment, it is recommended to use the workshop with frame structure.

In general, when selecting the required workshop structure, we should also comprehensively consider the economy, practicality and other factors, and select according to our own needs.

Several structural types of steel structures

  1. Steel structure frame
  2. Truss

H é ng Ji à: a structure in which members are hinged to each other at both ends. The truss is a plane or spatial structure composed of straight bars and generally has triangular elements. The truss members mainly bear axial tension or pressure, so as to make full use of the strength of materials. When the span is large, it can save materials compared with the solid web beam section, reduce the dead weight and increase the stiffness.

The advantage of truss is that the members mainly bear tension or pressure, which can give full play to the role of materials, save materials and reduce the weight of the structure. Commonly used are steel trusses, reinforced concrete trusses, prestressed concrete trusses, wood trusses, steel wood composite trusses, and steel concrete composite trusses.

  1. Grid

A spatial structure composed of multiple members connected by nodes in a certain grid form. The basic units that make up the grid structure include triangular cone, triangular prism, cube, truncated pyramid, etc. these basic units can be combined into planar triangular, quadrilateral, hexagonal, circular or any other form. It has the advantages of space stress, light weight, large stiffness and good seismic performance; It can be used as the roof of gymnasium, theater, exhibition hall, waiting hall, stadium grandstand canopy, aircraft hangar, two-way large column grid structure and workshop. The disadvantage is that the number of members converging on the node is large, and the fabrication and installation is more complex than the plane structure.

  1. Chordal membrane

The cable membrane structure system originated from the tents inhabited by human beings in ancient times (buildings composed of poles, ropes and animal skins). After the 1970s, the appearance of building membrane materials with high strength, waterproof, light transmission, smooth surface, easy cleaning and anti-aging, coupled with the rapid development of Engineering Computing Science, the cable membrane building structure system has made a comeback and has been widely used in public buildings in large spaces such as coastal tourism, Expo, literature and sports.

  1. Light steel structure

Light steel structure is a young and vigorous steel structure system, which has been widely used in general industrial, agricultural, commercial and service buildings, such as office buildings, villas, warehouses, stadiums, entertainment, tourism buildings, low and multi-storey residential buildings.

Light steel is also a vague term, which can be understood in two ways. One is “light steel structure of round steel and small angle steel” in Chapter 11 of the current code for design of steel structures (GBJ 17-88), which refers to the light steel structure made of round steel and angle steel smaller than l454 and l5636*4. It is mainly used for small structures that are not suitable to be made of reinforced concrete structures in the era of lack of steel. It is not widely used now, so it has been basically removed in the revision of the code for design of steel structures.

  1. Tower and mast structure

For structures with large height and relatively small cross section, horizontal load (especially wind load) is the main basis for structural design. According to its structural form, it can be divided into self-supporting tower structure and guyed mast structure, so the high-rise structure is also called tower mast structure.

With the development of industrial technology, various types of high-rise structures have emerged. In 1889, the Eiffel Tower was built for the Paris Exposition. The tower is 300 meters high. After 1921, a radio antenna and a television antenna were installed on the top of the tower, with a total height of 321 meters.
