Abstract: A structural member includes a coil shaped member having a coil radius measured from a center line, and coil length measured along the center line. A plurality of stiffener plates having opposing faces and opposing side edges are connected to points along the length of the coil shaped member, wherein the plurality of stiffener plates stabilize the coil shaped member and increases the bearing capacity of the structural member. Each stiffener plates has a length that is substantially the same as the coil length, and only on side of each stiffener plate is connected to the coil shaped member. The center line of the structural member may be straight or arcuate. Alternate embodiments may include additional coil shaped members.
