ABSTRACT:
A composite, pre-stressed structural member comprised of concrete and a lower metal support member, and method for forming and pre-stressing the same. The metal support member and a concrete mold are connected for parallel deflection with the support member uppermost and shear-connectors extending into the mold. The connected mold and support member are supported for deflection and concrete is poured into the mold and allowed to harden. During hardening of the concrete the mold and support member are deflected by the weight of the concrete, mold and support member, pre-stressing the support member. Upon hardening of the concrete and inverting to a concrete-uppermost position, a composite, pre-stressed structural member is provided.
