What types of steel column footings are available?

The footing design of steel columns can be of different types depending on the specific needs and structural requirements. Below are some common types of steel column footings:

steel column footings

  • Enlarged Base: The Enlarged Base improves stability by adding some enlargement to the bottom of the column. This design is often used where there is a need for greater horizontal loads or to reduce base stresses. 
  • Pad Base: A solid stone or concrete block is placed at the base of the column to provide better support and distribute the load.
  • Bolted Base: A bolted foot connects the post to the base using bolts. This design facilitates installation and removal of the post, and makes it easier to maintain.
  • Welded Base: A welded base connects the column to the base through welding. This design is often used for structures requiring higher flexural and torsional stiffness.
  • Fixed Base: The Fixed Base improves resistance to lateral displacement by securing the bottom of the column to the foundation. This design is often used for structures requiring higher seismic resistance.
  • Corbel Base: The Corbel Base is a design that provides a lateral cantilever at the base of the column to increase the bracing area.
  • Cantilever Base: A cantilever base increases the braced area by providing a cantilever at the base of the column, and is often used for structures requiring special bracing designs.

These types of column footings can be selected based on specific project requirements. Structural designers usually consider loading requirements, foundation conditions, and structural use to determine the most appropriate type of column footing.

Several cutting methods of steel structure space frame

图片
  Steel st ructure space frame s are now widely used, such as galvanized steel warehouse , glass dome building , airport hangar ,steel structure warehouses, hall roofs, gymnasiums, etc. The builder will cut, produce, and process according to the customer's requirements. There are many ways to cut steel structure space frame s, which will help you to have more choices of cutting. Then, the space frame   manufacturers below will give us a detailed description of several common cutting methods. The cutting methods of the steel structure space frame   are as follows: 1. Flame cutting by CNC machine tools: that is to say, use oxygen cylinders to oxidize and melt steel at a high temperature continuously. At present, natural gas is generally available, which is relatively reliable. 2. Waterjet cutting machine: Generally, high-pressure flowing water is used for cutting, and the accuracy is very high. It is often cut in some very thin, medium-thick steel that requires precision machining,

What are the advantages of steel over traditional concrete?

  steel warehouse Steel structures offer several advantages over traditional concrete structures that cover a wide range of areas, including speed of construction, flexibility, sustainability, and more. Here are some common advantages of steel construction:   Lightweight and High Strength: Steel is a lightweight and strong building material. Compared to concrete, the use of steel reduces the dead weight of the building, which in turn reduces the load on the foundation and lowers the overall weight of the building.   Fast construction: Steel structures can be prefabricated in a factory and then simply assembled on site. In contrast, traditional concrete structures typically require more on-site pouring and maintenance time. As a result, steel structures are often faster to construct, helping to shorten project duration.   Design Flexibility: Steel structures are strong and malleable and can support large spans and diverse building designs. This gives designers more flexibility in creat

Lifting construction of the starting unit frame of the large-span arched space frame

The space frame structure has good structural performance and a wide range of applications, especially for the installation of long-span steel structures. It has the advantages of saving steel, manufacturing technology, and convenient installation and construction. It is widely used in large-scale power generation facilities, petrochemical, coal f ields and other industries. In the construction of coal yards, in the past, most of the coal yards were piled in the open air, which caused great environmental pollution and affected the normal use of the coal yards. The coal raw material workshops of thermal power plants required relatively large building areas and spans (currently, the domestic span has reached 120m above), so that the steel space frame shell structure is widely used in the raw material dry coal shed workshop. The shell structure of the space frame of the dry coal shed has the characteristics of large span and high vertical height. During the construction process, it is ne
