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:
cross sectional area.
