ABSTRACT:
There is disclosed a prop-type damping device which effectively consumes energy of up-and-down vibration on a main girder of a bridge caused by earthquakes, winds, passing vehicles or the like to prolong a life of the bridge and improve comfort for bridge users with a simple constitution. The prop-type damping device comprises: an inclined prop member having a higher end thereof connected to a lower part of a main girder of a bridge to be horizontally movable relative to the same, and a lower end thereof connected to a position below a main girder supporting point of a pier or abutment for supporting the main girder to permit up-and-down movement of the higher end; and a damper connected to the higher end of the prop member and the main girder lower part to brake relative horizontal movements therebetween.
