The utility model discloses an elastoplasticity steel damping support, it sets up the steel damping element at support body lateral part, and the middle landing leg tip of steel damping element is articulated with the support body, and first landing leg and second landing leg tip are articulated with bottom plate or roof. The utility model discloses a steel damping element and ordinary bridge beam supports combine, can satisfy the requirement to earthquake power again when providing the whole functions of ordinary bridge beam supports, simple structure, and its mounting means is as good as with ordinary support, and the equipment is swift, does not influence the construction progress, does not have very big influence to the bridge elevation in addition, is favorable to bridge design's commonality, to the more frequent area of earthquake, selects for use the utility model discloses a protection bridge structures did not take place to destroy when the violent earthquake can not only be guaranteed to elastoplasticity damping support, under at ordinary times little vibrations or daily temperature displacement, only rely on support self to participate in the power consumption, and the power consumption was not participated in to the steel damping element, can effectively improve its life, has fine economic nature and market prospect.
