Beams are among the main components in the set of elements used in a variety of steel and construction structures. The main task of beam is to withstand the stresses caused by shear force, tolerating the bending anchor caused by the loads on the beam, and weight bearing. All steel structures are designed based on the existing bending anchor and the cutting criteria are controlled.
In the construction industry of high-rise structures, beams are defined as a long, prismatic and direct member whose task is to maintain the various loads incurred during the designed member. The main characteristics of the strains depend on three factors:
Beam web is one of the main components that interacts with many times in order to form the components of the beam or grider. It is clear that the beam can be exposed to elastic buckling from shear and bending torque and local compressive stresses of concentrated loads and structural actions and reactions, but usually the disintegration modes of such a strain occur under the loading of the incision caused by the buckling of the beam. For this reason, one of the most important and fundamental methods to increase the strength of the beam is to ripple the beam life.
What is sinusoidal or sin-beam sheet beam and what is its application?
Sin beams are one of the types of corrugated steel sheet beams called sin beams. For the preparation of sine sheet beams, thin sheets are usually used, which itself will cause a significant reduction in the weight of the structure due to the lack of need to use lateral hardeners. Therefore, the structures that are constructed with this type of beam sheets will always have a lower weight compared to the structures that are rolled with standard hot rolled profiles and ordinary sheet beams. Therefore, sin-beam is usually used to build huge structures such as an airplane hangar that require a larger opening.
Sin-beams (sin-beam) can increase the height of the beam with a thickness of 2ml to 1500ml. Therefore, it is obvious that with increasing the height of the beam, the bending strength of the cross section also increases, while the amount of steel consumed in beam web has only increased slightly.
In general, it can be said that web beam tolerates slight bending stresses and eliminates the possibility of buckling in the pressure zone. But this is if web and Wings are constantly welded together. But sinusoidal web contributes to the tolerance of bending forces and on the other hand adds to the level of cross-section capacity. Therefore, in addition to the presence of rippling john or sine sheet beams reduce the free width of the load under pressure, they also increase the local buckling capacity of the pressurized load.
Many experiments are carried out on sine sheet beams, one of which has shown that these types of beams are also exposed to similar local tension under the load site. But because the sinusoidal wavy web exposes a longer level of life to a concentrated load, it has more buckling resistance and therefore its resistance is higher than the conventional flat life. One of the most important advantages of sinusoidal sheet beams is the following:
From design to complete implementation of industrial shed with Sinusi beam (Sin-Beam)
Pouladin Dej Company, to date, has completed and implemented 10 projects for construction of industrial shed with sinusoidal web. One of the most important concerns of Pouladin Dej Company is the use of specialists in this field to provide the best and most accurate designs to its customers and to carry out the process of making sin-beam in its most professional form.
