Quake-resisting method of building structure

The invention discloses a quake-resisting method of a building structure. The method involves an existing building frame, and includes the steps that first, first steel ropes are led out from beam-column joints of upper beams at joint space of the building frame, meanwhile, second steel ropes are led out from beam-column joints of lower beams, the other ends of the second steel ropes are anchoredinto beam-column joints on the other sides of the upper beams, then the first steel ropes and the second steel ropes are connected through connectors, and then every two connected steel ropes are tensioned or subjected to prestress to form a quake-resisting device; the quake-resisting devices are arranged in pairs in each frame and at all floors. Beams and columns in a whole building are connectedin a tied mode through the quake-resisting devices with steel rope assemblies, and therefore the quake-resisting devices can provide extra tension for the building structure to prevent the building structure from being greatl
