The invention provides a replaceable beam-column joint earthquake damage control device. The device comprises flange energy consumption fuses which are arranged in connection gaps of beam flange plates arranged in pairs; the upper face and the lower face of each flange plate are both provided with the corresponding flange energy consumption fuse; the flange energy consumption fuses are provided with bolt holes; the flange energy consumption fuses are fixedly connected with beam flanges through friction type high-strength bolts. The replaceable beam-column joint earthquake damage control device is simple and reliable in structure and convenient to install; damage control can be performed on the structure, and connecting joints are protected; vibration energy caused by an earthquake is dissipated, and vibration responses of a building under an earthquake are reduced; replaceability is good, and after an earthquake ends, damaged elements can be fast replaced under the condition that use of the building is not affected.
