ABSTRACT:
A composite bearing column comprises a solid metallic core of circular or polygonal section free from reentrant recesses. The core is embedded in an intermediate layer of mortar which is compatible both with metal and with concrete. An external concrete mass surrounds the intermediate layer. Metallic bars are longitudinally distributed around the central core in that concrete mass and extend lengthwise of the column parallel to the core. The bars are welded at their opposite ends to a base plate and to a head plate. In one embodiment, mounting rings are secured to the base and head plates and extend toward each other; and a metallic wire helically surrounds the bars.
