Reducing Masses of Supporting Structures Using I Beams

First of all, the weight of the I beam is an important factor in the carrying capacity, it helps immensely during construction work. But what is an I beam? An I-beam is a metal-profile construction on the floor surface, oblique or horizontal, designed primarily for beam bending. Most importantly, it is influenced by the weight load which is directed vertically. In fact, this is the primary effect that the rolled metal section must withstand.

Technical characteristics of the rolled metal section as explained by SuperStructures must be taken into account in order to apply them correctly in construction, because, despite a wide variety of ranges of use, the essence remains the same – to create a sturdy supporting structure. It allows you to transform the buildings architecture.  An I beam:

✓    increases the span width of buildings;

✓    significantly, by about 35%, reduces the weight of the supporting structures;

✓    significantly increases the profitability of building projects.

Speaking about advantages of the design, cons should be noted as well, although there are only few of them. They are:

✓    the need to use additional reinforcement when creating reinforcement ribs;

✓    sufficiently significant labor costs that are needed for its manufacture.

However, it should be noted that on the other hand, additional beams make it possible to:

✓    reduce the overall metal content of the welded metal, as it significantly reduces the wall thickness. Thus, it is possible to lower its cost, but to fully preserve the mechanical characteristics;

✓    In addition, the lightweight construction is also cost efficient from the foundation device perspective, since after reducing the total mass, you can use the foundation for QMB (quick-mounting buildings).

To find an I beam suitable for a particular construction building, you need to make some calculations. Usually for this purpose you can use tables or online calculators. They are based on two given parameters: the distance from one wall to another and the future load on the building structure.

The strength of an I beam is determined by such parameters as:

  •       length;

  •       fixing method;

  •       form

  •       cross sectional area.

The length of an I beam is different, that is, depending on the gauge, dimensions and weight of the I beams differ one from another. In addition to the length, the weight is determined by the thickness of the metal and dimensions of the edges. Therefore, to perform various calculations, the concept of “I beam weight per meter” was introduced. When buying a welded structure, you need a calculation for strength, as well as for a specific use, or beams for sale and also a calculation for deflection. Competent calculation the I beam load will ensure stability of the structure to the design impacts, that is, the ability to perceive them without destruction. To determine, if necessary, the weight of an I beam, we use special tables, where you can find its characteristics, for example, dimensions, steel grade, etc. The table shows the theoretical mass of 1 m profile. Knowing these tables will help you in reducing masses of supporting structures using I beams.
