| Abstract: | Prestressing technology was applied to the construction of the China Century Monument, unbonded prestressing for the floors of Zone A and bonded prestressing for both the beams of Zone B and the overpass. QM anchor system and 1860MPA strands were applied and some strands were stretched by angle varying tension technology. The tension was controlled by both stress and extension. |
