Abstract
The use of composite columns is increasing due to the combined cooperation of concrete and steel in many structural systems around the world. Composite columns not only have many advantages in construction but also significantly improve the mechanical properties of structural members compared to reinforced concrete and steel members alone. These include increased enclosure, increased shear strength and thus increase member efficiency. Also, the use of composite columns reduces the final cost of construction of the structure. In Article B, two specific types of CFT and SRC columns with steel fibers are discussed and with the help of ABAQUS finite element software, these columns are modeled and subjected to cyclic loading and their energy absorption and hysteresis diagrams are compared with each other and their advantages and disadvantages. It is specified and finally how these structures help to reduce the final cost is examined.
