Numerical Investigation of the Impact of Steel Profiles and Embedded Stiffeners in Circular and Square Concrete-Filled Steel Columns under Axial and Lateral Loading
Mohammad Amin Hamidi Moghadam
Concrete-filled steel tube (CFST) columns are widely used in high-rise buildings around the world due to their numerous structural advantages, including high load-bearing capacity, favorable inherent ductility, substantial energy absorption capabilities, and the elimination of the need for formwork. However, in Iran, these structures have not yet been widely implemented in practice, highlighting the need for further research in this area. Additionally, challenges such as buckling and local delam
