Composite columns in the form of steel boxes or tubes filled with concrete are called Concrete Filled Pipes. Sectional steel profiles are generally rolled boxes consisting of steel structures or pipes produced in large quantities in the country. For more information on World class steel cans visit our site.
Notable cases about World class steel cans
Ordinary concrete or self-compacting concrete (SCC) can be used in the cross section of the concrete core. The composition of steel around the concrete core creates a composite cross section. Various roof systems and steel beams are used with these columns. CFT columns have excellent properties such as high tensile strength, high ductility and high energy absorption capacity. In addition to significantly increased structural properties, CFT columns can significantly reduce construction time. The steel shell acts as a longitudinal and transverse reinforcement.
The shell also provides a closed pressure for the concrete, which puts the concrete under pressure from all directions. In other words, the steel shell reinforces the concrete core. This can prevent the steel pipe from buckling and increase the stability and tensile strength of the steel column. In CFT columns, placing the steel wall around the section where bending and tensile stresses are most effective causes a significant increase. hardness and resistance are cut.
Benefits of the cans
- 1 Axial load carrying capacity and high bending.
- 2 Energy absorption resistance High softness (ductility).
- 3 Increase the strength of concrete due to containment
- 4 critical times in a sprain (more difficulty).
- 5 Higher shear strength.
- 6 Hold the mold for the concrete core.
- 7 Protect the concrete surface from damage
- 8 It is economical compared to steel and concrete columns. (Kg of iron consumption per square meter)
- 9 Less production time.
- 10 Easier shipping.
Due to the use of metal boxes to strengthen the cross-section longitudinally, to withstand forces and anchors, Transverse reinforcement (transverse reinforcement) is effectively reduced in concrete. In CYCLIC and CFT columns with varying loads, it has been proven that the possibility of local buckling at the end of the metal box is very difficult by breaking and breaking the central concrete. The results show that under hysterical loads, fracture is unstable, especially in columns with high axial loads.
To achieve the behavior of CFT columns under different factors, it is undoubtedly necessary to know exactly each of the parameters affecting their performance. So that if this knowledge is not obtained, these sections can not be used economically and reliably in a variety of structures. The most important factors influencing the behavior of such sections include column slimming and steel wall compaction, concrete entrapment, type of concrete and steel used, creep and drop of concrete, type of structural joints and adhesion between the two materials and the degree of fire resistance of these sections.
