Abstract: Site cast or pre-cast columns aligned and braced by pre-cast pre-stressed floor beams are used to erect a concrete skeleton structure for a building. The ends of the horizontal beams are imbedded in the columns at floor levels to stabilize and complete the skeleton. The horizontal beams are pre-stressed and are cast with passages that permit insertion of continuous reinforcing tendons into a network throughout each floor level.

The beams are usually integrated (buried) into each monolithic floor slab, keyed, doweled and bonded with bonding agent at cold joints to become a part of the slab structure.
