The invention provides a self vibration/shock reduction water pool applicable to a suspended building structure, comprising a water pool body and a top slab of the water pool, the water pool is positioned in an interior span area of the suspended building structure, and at least one side of the water pool is used to be connected with a beam. The self vibration/shock reduction water pool can be flexibly arranged in the building structure with diversified forms, and can be an independent water pool; the self vibration/shock reduction water pool also can consist of a plurality of water pools, at this moment, at least one side of each water pool forming the self vibration/shock reduction water pool is used to be connected with the beam. The self vibration/shock reduction water pool has the advantages of low investment cost and good vibration reduction effect. The mounting method of the self vibration/shock reduction water pool particularly comprises the following steps: (1) the water pool is manufactured and mounted in the interior span area of the suspended building structure, and the bottom of at least one side of the water pool is supported on the beam; (2) liquid is injected into the water pool to the designed height; (3) the top slab is arranged on the top of the water pool.
