Aiming at the high level fire pool as damper in fire water supply system of super high-rise building, new problems caused by the combination of structural damper and high level fire pool were analyzed based on functional requirements of structural damper and high level fire pool. Because the fire pool water was in the state of daily movement, it brought about the water level change, reliability of the connection and storage volume, fire water anti-freezing, strength of the fire pool and change of its internal structure. The design needed to meet the functional requirements of fire pool and damper of a super high-rise building. The problems were analyzed, and it was proposed that tech. measures should be taken to strengthen high level fire pool as damper from the aspects of effective volume guarantee, flexible connection of pipes and determination of effective water level and strength of pool structure.
