In the constructions, many beam kinds may be seen. They are grouped depending on the components used in construction, how the beams are arranged to support them, and other unique characteristics. Let’s go through each classification in more depth. Following is a discussion of how beams may be classified based on their construction materials.
Building Materials
Based on the different types of materials, the following classification is created.
Cement Beams
Different types of concrete beams are built with varying cross sections. This hohlbalken is typically made of reinforced concrete and are used to support loads. They may primarily be divided into two types: rectangular beams and circular beams.
Metal Beams
There are many different kinds of steel beams that are used as beams to support loads. We define the universal beam primarily as the steel beam that supports the load. Additionally, it is stiffer in the direction of bending. Additionally, beams like plate girders are employed to support the large weights. Steel beams can also be made of steel pipes, C channels, rectangular hollow sections, solid pipes, etc.
WPC beam
In various places of the world, wood is a very common building material. WPC beam are also incredibly enormous and towering constructions made of timers. WPC balken constructions utilise time beams as load-bearing components. Since the endurance of the constructions is frequently an issue, treated wood is employed in construction.
Integrated Beams
As implied by the name, the materials are combined to increase the beam’s stiffness. Steel and concrete are primarily used in the casting of composite beams. These beams are frequently seen in steel buildings.
Based on hollow beam support types
Uncomplicated Supported hollow beam
Two supports are present, and they permit rotation at the support. As a result, the beam’s edge is allowed to revolve. Depending on how the loads are arranged, the bending moment will be at or close to its maximum at the mid-span. At the supports, the shear force will be at its greatest.
Constant Beam
The beam is known as a continuous beam when there are two or more supports. There will be a bending moment in each support depending on the boundary condition. There won’t be any bending moment at the end supports if the beam is constructed with knife-edge supports in mind. The influence of the concrete columns or the stiffness of the concrete column must be taken into consideration in the analysis if we are building a concrete beam supported by concrete columns. The results are significantly influenced by doing analyses as knife-edge supports and column supports.
Beam Cantilever
The beam must be built for the cantilever bending moment whether it continues to the other spans or terminates at the support. The cantilever bending moment cannot be distributed in time.
Unfinished Beams
They are the kinds of beams, as the name implies, that are cast individually and set in the appropriate spot. When there is repetition of labor, this style of construction is now growing in popularity. It is possible to cast beams in bulk, then install them. This strategy saves time and money at the same time. The regular beam might serve as the reinforcement for the beam. However, there could be some change in the reinforcement area depending on boundary circumstances, etc. Depending on the structure, special connecting features may be used to preserve continuity.
Post-tension beams and prestress beams
Prestress simply implies that the wires are stressed before the beam is cast. In the building of post-tension beams, the tension of the cables is completed after the beam has been cast. Building a post-tension beam involves two steps. The transfer stage and service stage are those. We build with transportation in mind throughout the transfer step. When we put a load to a beam, it is the service stage. To sustain enormous spans, post tension and precast beams are frequently employed. When building bridges, these beams are frequently employed.

Beam Deep
We build deep hollow beam to support wide spans, heavy loads, etc. The transfer floor structure is where deep beams are most frequently seen. In multistory structures, column spacing results in more parking spaces. Beyond that point, we cluster columns for a variety of reasons. A deep beam is built at this level to support the weight put on it by the building above the transfer floor.
When designing the deep beam, there are specific steps that must be taken. You could refer to the article deep beam design for further details.
Classification of Beams based on Cross-Sectional Area, L-Shape, T-Shape, Rectangular, There are several beam types made from various angle sections, including “L” and “T” shapes, among others. Additionally utilized as hollow beam sections are rectangular hollow sections, circular hollow sections, and rectangular and circular solid sections.
