A bridge damping support comprises an upper support plate fixedly connected with a bridge body, and a lower support plate fixedly connected with a pier, wherein a middle sliding block with a spherical lower plate surface, an upper hemispherical turning block and a lower hemispherical turning block are arranged between the upper support plate and the lower support plate; a retainer ring is arranged on the periphery of the upper support plate; a limiting ring is arranged on the periphery of the upper plate surface of the lower support plate; the upper hemispherical turning block and the lower hemispherical turning block [5] are split; a damping spring is arranged between the upper hemispherical turning block and the lower hemispherical turning block. The bridge damping support reduces damage of a secondary internal force to a structure on the premise of meeting a daily temperature change displacement requirement of a bridge structure, and is reasonable in structure, safe and practical; the bridge damping support reduces damage of earthquake energy to the pier, and meets shock-isolating, energy-absorbing and damping functions during an earthquake; the bridge damping support facilitates conversion and consumption of kinetic energy and potential energy; the bridge damping support can significantly consume energy through shape change and has a better shock-absorbing effect.
