Abstract
A stressed tension member includes tension elements positioned in a tubular sheathing member extending through and encased in a structural concrete component. The tension member also includes grout which along with the tension elements completely fills the transverse cross-section of the sheathing member. The tension member is anchored to the concrete components. If necessary, by releasing the anchorage, the tension member can be removed from the concrete component and replaced by another tension member, since the member is separated from engagement with the concrete component by the sheathing member.
