A series of full-scale rectangular steel reinforced concrete(SRC) columns confined with a newly innovated multi-spiral cage were tested under monotonic axial compression and cyclic lateral load.The multi-spiral cage is a device of two interwoven spirals including a "circular spiral" at the center and a "star spiral" surrounding the perimeter of the column.The innovation of applying the star spiral to the rectangular SRC column is to take its advantage in concrete confinement at the four corners… CONTINUE READING
