The tubular members of concrete steel (CFST) use the advantages of both steel and concrete. They consist of a hollow section of circular or rectangular steel filled with smooth or reinforced concrete. They are widely used in high-rise and multi-storey buildings such as columns and beams-columns, and as beams in low-rise industrial buildings where a robust and efficient structural system is required. There are a number of distinct advantages related to such structural systems in terms of structural performance and construction sequence. The problem of inherent buckling related to thin walled steel pipes is avoided or delayed due to the presence of the concrete core. In addition, the performance of the concrete filler is improved due to the confinement effect exerted by the steel casing. The distribution of materials in the cross-section also makes the system very efficient in terms of its structural performance. The steel is located in the outer perimeter where it is realized with greater effectiveness intensity and flexion. It also provides the highest stiffness since the material is further away from the centroid. This, combined with much higher modulus of elasticity, provides the greatest contribution to the moment of inertia. The concrete core gives the greatest contribution to the axial compression strength. The use of steel pipes filled with concrete in building construction has experienced a resurgence in recent years mainly due to its simple construction sequence, in addition to its superior structural behavior. Typically, it was used in composite structure structures. The hollow steel tubes manufactured or laminated were first erected to support the construction load of the upper floors.
