The invention discloses a friction sliding energy-consuming and damping device of a multi-span simply supported beam. The friction sliding energy-consuming and damping device comprises a plurality offirst hydraulic cylinders which are vertically arranged, a horizontal plate is arranged at the top ends of the first hydraulic cylinders, and the horizontal plate is provided with a plurality of groups of bridge sliding devices. Pressing-pushing devices are arranged on one sides of second vertical plates, the pressing-pushing devices comprise hydraulic pressing-pushing oil cylinders, and the hydraulic pressing-pushing oil cylinders are provided with distance measuring sensors and pressure sensors. One ends of the hydraulic pressing-pushing oil cylinders are connected with third vertical plates, and the other ends of the hydraulic pressing-pushing oil cylinders are in contact with the third vertical plates. The second vertical plates are provided with inclined rods used for supporting the hydraulic pressing-pushing
