The invention discloses a BIM-based RC frame structure earthquake damage judgment and loss prediction method, which comprises the following steps: directly carrying out earthquake response analysis on a BIM model in Revit through a model conversion function of RTO (Revitto OpenSEES), respectively obtaining building damage levels under the earthquake action from three levels of components, floors and a whole structure according to a Building Anti-seismic toughness Evaluation Standard, and carrying out BIM-based RC frame structure earthquake damage judgment and loss prediction. The component earthquake damage information is automatically stored in the BIM model, so that the management and integration of the earthquake resistance information of the building structure in the whole life cycle of the building are realized; based on the existing project quota, the structure construction cost is automatically obtained in the Revit, then the post-earthquake repair cost, the earthquake repair time, the number of casual
