In industrial buildings, steel columns play an extremely important role. This structure is built to withstand and resist pressure from the loads above, and plays a key role in supporting the structure. Let's join Hai Long Construction to learn about types of steel column structures and general principles when arranging them in construction through the following article.
What is steel column structure?
Steel columns are a type of load-bearing structure used in the construction of workshops, factories and other industrial projects. This is a structural component designed according to the vertical shape of the house frame, with high durability and rigidity to ensure the ability to withstand large loads and keep the building safe. Steel columns are often diversified in shape and size to suit the specific requirements of each project.
Steel columns are responsible for receiving loads from other components such as roofs, beams, trusses and transmitting them to the foundation. The structure of steel columns includes three main parts:
- Column head: This component is responsible for supporting the components above and distributing the load to the cross-section of the column body.
- Column body: This is the main load-bearing part, receiving and transmitting loads from above to the base of the column.
- Column foot: This component connects the column to the foundation and distributes the load from the column to the foundation.
Classification of steel column structures
Columns in steel structure projects are quite diverse in form, depending on the specific requirements of each project. They are divided into two main types: columns with variable cross-section and columns with constant cross-section.
Column cross section changes
A variable cross-section column is a type of column designed with a variety of sizes along its length. Normally, this type of column is preferred for use in cases where factory cranes have high lifting capabilities. The position of changing the cross-section of the column is where the load from the crane is transmitted to the column through the column shoulder.
Using variable cross-section columns makes the installation and transportation process more convenient. However, during the design and calculation process, the implementation specialist needs to ensure the stability of the column and the load-bearing capacity of each different part of the column.
Column cross section does not change
A column of constant cross-section is a type of column whose cross-section remains constant throughout its length. Column sections can be constructed in solid or liquid form. With a column of constant cross-section, the load from the crane is transmitted to the column through the cantilever beam connected to the column. This type of column is often easier to design than columns with variable cross-sections, however, its load-bearing capacity is often not as good.
General principles when arranging steel column structures in construction
Complying with general principles when arranging column steel structures plays a decisive role in creating a sturdy, long-lasting structure. Here are some general principles:
- To perform column design, a study of bending moments is necessary to calculate steel columns.
- The shear force in the column is usually less than the shear capacity of the concrete. Therefore, arranging the column according to the correct structure is important to ensure quality.
- The ability to withstand torsion is often overlooked, so designers will often add a column to withstand torsion. The design of the torque part needs to be done to be most compatible.
- The column subjected to compression will often be obliquely eccentric, so special attention should be paid to dangerous combinations according to the largest moment. A team of professional workers must make accurate calculations for the reinforcement of the assemblies, avoid shortcomings to ensure sturdiness, and at the same time avoid wasting resources.
- The vertical force in the house column has negligible change, but the bending moment has a large fluctuation, especially at the two ends of the column. Column arrangement requires careful calculation in both cross-sections to ensure accurate and safe column connections.
