As you know, beam is one of the main components of any steel structure . Of course, ironworks are also widely used in concrete structures.
The main task of the beam in each structure is to bear the different loads on the structure, which may be static or dynamic i.e. variable and sudden, so what is very important in the beams is the degree of resistance of the beam against the loads entered into the structure.
In fact, different beams used in a structure should have the ability to withstand the incoming loads and transfer it to the columns and walls so that it can be transferred to foundation and ultimately the ground.
If the resistance of the beam is standard and a correct beam score is used for the project, we will have a stable structure against accidents such as storms and earthquakes. Otherwise, the structure may collapse due to increased loads .
Currently, all beams made in iran or other leading countries in the field of steel and iron such as Russia, China and Europe comply with a set of internationally approved standards.
Of course, the remarkable thing is that there are also fake and low-quality beams on the market, so employers and celebrities should be careful when buying beams.
What you need as the resistance of the beam to transfer loads on the structure is only caused by beams that are produced under the necessary standards.
In fact, the strength of the beam used in the structures should be such that it can withstand the calculated stress and tensile pressures well.
Accordingly, the most important standards for making profiles and beams are :
IPE standard is a standard used to increase the resistance of beams in Iran . Of course, Russia and China also use this standard alongside other standards. The dark characteristic of this standard is that as we approach the beam, the thickness of the wings increases.
Beams made according to INP standard have a cross-sectional surface in the form of I . The wing thickness of beams made under this standard is initially thin, but gradually thickens .
The INP standard is written by China and Russia, and therefore it is mostly produced in these two countries, i.e. in most projects that we need this type of beam in Iran, we need to use imported beams.
Of course, in some domestic steel mills, this standard is also used limitedly, but still the sheets that are needed to make them are imported from Russia, Ukraine and China.
The strains that are made under this standard are also called beams, which are more resistance because their wings are wider because the forces enter a wider cross section. Accordingly, they are also called wide-winged beams.
When you look at these beams from the symag, they are in the form of H and have a lot of application in a variety of structures.
So that every unprofessional person is familiar with them. The resistance of the beam is such that it can withstand the loads on the structure in both directions and therefore have more stamina.
The strength of the beam, which is the same as the load bearing of the beam, depends on various items such as size, dimensions, cross section, standard used for the manufacture and material of the alloy used.
Accordingly, the strength of beams made in different factories or different countries can be completely different .
In general, each beam consists of two parts :wing and soul .
The higher the thickness and length of the beam and the more resistance of the beam against the types of forces entering the structure .
The opposite is true. On the other hand, depending on the amount of carbon used in steel used as raw materials for the construction of beams, its hardness is also higher and has a higher resistance .
Note that if the beam is to be used to control a concentrated load in the structure, you should be more careful in choosing the type of beam and use the types that have higher resistance .
The higher the strength of the beam, the higher the price, but for large loads, beams with less resistance can also be used in high numbers to create the necessary stability for the structure .
These sections are produced in different forms, each of which has special tasks in the structure. For this reason, the strength of the beam will vary based on the role it plays in the structure. In this regard, beams are divided into the following types :
It's the same main beam that should have the most resistance in the structure . Because as the most important member of the structure, it should be able to withstand the main loads entered and transfer them to the side joists without causing damage to the beam or structure.
These types of beams are attached to columns or ceilings so that they can transfer structural loads to the column through joists.
Joists are a type of sub-beam that is placed in high numbers between the king of the arrow and the wall or column to take the loads of the roof from the king and transfer it to the wall or column.
These types of beams are placed in the opening parts of the building, such as windows and doors, to keep the brick walls attached to them stable.
These sections are only used next to the building in the coiling section to increase the building's resistance to additional forces. In fact, these beams strengthen both ceiling beams and perimeter walls in terms of resistance.
