چکیده
Special-shaped concrete-filled steel tube (SCFST) columns have a higher bearing capacity, ductility, and energy absorption compared to other columns. Due to their special shape, the columns can be utilized in different parts of the building without protruding members. In L-shaped CFST columns, this study investigated the effect of various parameters (such as yield stress of steel wall, characteristic strength of concrete, height of column, thickness of steel wall, and geometry of stiffeners) on the eccentric load bearing capacity. In other words, the bearing capacity has been measured based on the optimal performance of these columns under the effect of axial and eccentric loads. The results of this study showed that the bearing capacity of L-shaped CFST columns is highly dependent on all the parameters mentioned above, and that the column's optimal performance can be determined by carefully selecting and optimizing these parameters. The ratio of load-to-weight (P/W) has been considered.
