Despite these advantages, you can design simple five-story projects as well as various complex designs using this type of building frame. Therefore, with the advancement of the construction industry, steel frames play a crucial role in executing flawless projects. These structures are among the modern pillars of construction and are a suitable option for reducing building costs.
Standards for Executing a Five-Story Steel Frame Building
To ensure safety, quality, and proper performance of steel frames, national and international standards are considered for such projects. Standard 2800 is a national standard for the design and execution of building frames that sets requirements for reinforcing the frame against earthquakes. Standard 300 is another standard that specifies the requirements related to the analysis, design of steel sections, and loading of these sections.
In addition to national standards, international standards such as ASTM and AISC are applicable for the design and construction of steel frames. These standards provide guidelines for selecting materials and welding techniques, steel sections, and the design, construction, and installation of steel frames. If steel frames are erected according to national and international standards, their durability and strength will be enhanced.
Regulations for Constructing Steel Frames in Five-Story Buildings
Some of the most important regulations to consider during the execution of steel frames for five-story buildings include:
- Safety Regulations: This includes employee training, securing equipment, adhering to safety principles during installation, and quality inspection and control.
- Construction Principles Regulations: These describe how to place columns, the positioning of column bases, and how to carry out various construction stages for steel frames.
- Municipal Permits: This includes building permits required before starting the steel frame and permits and restrictions regarding the height and design distance of the building facade.
- Environmental Regulations: This involves pollution reduction and management of construction waste.
Stages of Executing Steel Frames in Five-Story Buildings
The execution of steel frames for five-story buildings involves several stages that require adherence to predetermined regulations and standards. The main stages of executing steel frames include:
➕ Foundation and Base Construction
The first stage in executing steel frames for multi-story buildings is to construct the base and foundation using rebar and concrete. Initially, the soil’s load-bearing capacity is determined to select the best type of foundation. Then, excavation of the project site is carried out, followed by leveling and equalizing the ground. Finally, the ground is covered with concrete, and rebar is installed.
➕ Column Base Construction
In the next step, the column bases must be installed on the foundation. At this stage, the exact location of the column bases is determined on the blueprint, and then the column base is placed in the specified location.
➕ Construction and Installation of Main and Secondary Beams and Columns
➕ Construction of Bracing for the Project
Bracing is a part of the steel frame in various buildings that transfers lateral forces to the columns and protects the structure against earthquakes and wind. Braces are placed between the columns and beams, connecting from one column to another. They are then welded together, ensuring their placement is secure. There are various types of braces, and the best type is selected based on the building’s requirements.
➕ Final Review of the Steel Frame
In the final stage, after the installation and execution of the steel frames are complete, you need to inspect the bolts and welds of the project. If there are any defects or issues in the connections, they should be addressed. This will enhance the quality, durability, and longevity of the steel frames.
