Steel skeleton of a three-story building

The steel skeleton of a three-story building is a type of strong and relatively new framework used for constructing high-rise structures. This framework consists of a regular network of steel beams and columns, providing significant durability. In order to implement a metal structure in three-story buildings, various stages must be followed, and it is essential to know the required amount of beams and the type of beams needed.

Various types of bolted and welded frameworks can also be used for constructing three-story buildings. To learn more about this type of framework and its implementation in three-story buildings, stay with us.

Suitable Beams for a Three-Story Building

Before familiarizing ourselves with the installation and execution stages of the steel skeleton for a three-story building, let’s identify the suitable beams for such structures. Overall, the geographical environment and the region where the project will be executed are the most important factors determining the type of beams suitable for multi-story buildings. For instance, humid environments and dry environments each require a specific type of beam, and earthquake-prone areas also have their own specific beam requirements.

You should pay close attention to the weight of the building and the required resistance when selecting the most suitable beams for three-story buildings, choosing one from the available options in the market. For more information on how to select the appropriate beams for multi-story buildings, you can consult our advisors at Saman Dez.

Stages of Installing the Steel Skeleton for a Three-Story Building

Typically, the necessary materials for constructing the steel skeleton of three-story buildings are delivered to the project site and used for construction. The stages that must be followed for the installation and execution of the steel skeleton in three-story buildings and small projects are as follows:

• Foundation execution
• Installation of column plates and bolts
• Placing the steel columns
• Installing beams on top of the columns
• Installing braces and necessary supports

We will elaborate on these points further.

In the third step, the steel columns of the three-story building are positioned within the structure. A crane is required for this stage, as the columns are lifted from the ground and, once vertical, are connected to other components. Interestingly, the secure connection of each column to its respective column plate is referred to as a rigid connection.

Important Points for Executing the Steel Skeleton

Do not forget that even a small mistake can compromise the strength of the steel skeleton in a three-story building, potentially leading to collapse over time. Here are the most important execution points for this type of framework:

• Always ensure that the initial foundation stage is entrusted to the main contractor to guarantee its strength.
• Exercise high precision when loading the required components for the steel framework and transporting them to the installation site.
• Do not allow the installation crew to work until the necessary safety conditions for the project have been met. Installers should wear appropriate safety gear and be aware of safety protocols.
• While the speed of executing the steel skeleton is extremely important, it should not come at the expense of accuracy and quality of the structure.
• Obtain installation and execution services for steel frameworks in multi-story buildings from reputable companies like Saman Dez to ensure structural integrity after installation.

Required Amount of Beams for the Steel Skeleton of a Three-Story Building

In general, the amount of beams used in the steel skeleton of three-story buildings is not fixed and varies based on several factors. The type of framework chosen by the builder is the most significant factor influencing the required amount of beams.

If you choose steel frames with convergent braces, approximately 40 to 70 kg of beams are required for each square meter of construction. For steel frames with divergent braces, you will need about 45 to 80 kg of beams per square meter. Additionally, for constructing a steel frame with a moment-resisting frame, around 60 to 100 kg of beams are needed, and for a steel frame with a dual system, about 60 to 120 kg of beams are required for each square meter. Any changes in the construction and execution process of the steel skeleton for a three-story building may lead to an increase or decrease in the amount of beams used.

Price of the Steel Skeleton for a Three-Story Building

One of the most important factors influencing the type of framework for different buildings is the price of the skeleton. Steel frames are reasonably priced given the strength and durability they provide to the structure. This price can vary based on various criteria.

For example, factors such as the type of beam selected, the weight of the beams, the dimensions of the structure, the quality and durability of the structure, and the method of execution—whether bolted or welded—impact the final price of the steel skeleton for three-story buildings. To ensure that you implement these types of metal structures at a reasonable price at the project site, you can take advantage of Saman Dez’s services.

conclusion

At this stage, we have examined the steel skeleton of a three-story building. Three-story buildings are often considered small projects, and their steel frameworks are erected on-site. The execution of this type of framework involves several stages, including foundation execution, installation of column plates, placement of columns, installation of main and secondary beams, and finally, project review and rectification of any issues. If you entrust the execution of such projects to a reputable and experienced company, you will certainly achieve a durable and long-lasting structure.
