Abstract

A bolt tensioning assembly includes a bolt having a through-hole extending longitudinally through the bolt. A ram is inserted into the through-hole. A top cap is configured to be attached to a first end portion of the bolt. A load distributing member is configured to engage the ram at a location adjacent a second end portion of the bolt to distribute a force exerted thereon by the ram, and an actuator is connected to the top cap to exert a force on the ram to cause the ram to engage the load distributing member such that the bolt is placed under tensile stress.
