THE EFFECT OF USING STEEL FIBERS IN THE CONCRETE OF CFT, SRC AND SRC COMPOSITE COLUMNS ENCLOSED WITH FRP COATING AND COMPARING THEM AGAINST CYCLIC LOADS
The use of composite columns is increasing due to the combination of concrete and steel in many structural systems around the world. Composite columns not only have many advantages in construction, but also improve the mechanical properties of structural members compared to concrete and steel members alone. These include increasing the chamber, increasing the shear strength and thus increasing the efficiency of the members. Also, the use of composite columns reduces the final cost of building the structure. In this research, three special types of CFT, SRC, and SRC columns reinforced with fiber reinforced concrete with FRP coating were discussed and with the help of ABAQUS finite element software, these columns were modeled and subjected to cyclic loading, and energy absorption diagrams and Their hysteresis is compared with each other. The advantages and disadvantages are identified and finally how these structures help to reduce the final cost is investigated and it was also determined that the reinforced columns with the help of FRP show better behavior.
