The seismic damping bearing structure is more reasonable, the performance is more reliable, and the service life is longer.

該支座包括固定支座（代碼為GD）、單向支座（代號為DX）、雙向支座（代號為SX）三種型式，22個等級，其水平承載力、豎直方向拔力及支座的整體強度均比普通支座有大幅度提高。該系列支座采用彈性減振元件，當水平力大到一定程度后，減振彈簧開始發生彈性變形實現緩沖作用。當結構發生轉角時，球芯產生轉動，釋放上部結構產生的轉矩。地震時，剛性抗震措施和柔性減振措施同時發生作用，以抵御巨大的地震輸入能量，這樣既能保證橋梁上、下結構合理相對位移，減小地震力的放大系數，又使結構保持統一性。該支座可抵御8-11度地震，對高烈度地震區尤其直下型地震區的工程結構有良好的抗震減振作用。
The bearing comprises a fixed support (code GD), one-way bearings (codenamed DX), bidirectional support (codenamed SX) three types, 22 grades, bearing capacity, the level of the overall strength of vertical pulling force and bearing are better than ordinary bearing has greatly improved. The series of supports adopt elastic damping element. When the horizontal force is large to a certain extent, the damping spring begins to deform elastically to achieve the buffering effect. When the structure rotates, the ball core rotates to release the torque generated by the upper structure. When the earthquake, the rigid and flexible measures to reduce seismic measures happen at the same time, in order to resist the earthquake input energy is huge, so as to ensure the bridge, reasonable structure displacement amplification coefficient decreases with the force of the earthquake, and the structure of unity. The support can withstand 8-11 degree earthquake, and has good seismic and vibration reduction effect on the engineering structure in high intensity earthquake area, especially in the lower earthquake zone.
