The stiffness of the structure will change after the broken column is jacked up, which directly affects the overall seismic performance of the structure. But up to now, the design method and construction technology of the broken column jacking are not standardized, so it is of great engineering significance to study the seismic performance of the frame structure after the broken column jacking. In this paper, the data before and after jacking and after reinforcement of the whole broken column jacking project of a five-story frame structure in Jinan high tech Zone are simulated and analyzed. Based on the stiffness, El Centro seismic wave, Taft seismic wave and Tianjin artificial wave are selected to analyze the dynamic time history of the structure. Through the study of the change of seismic performance of the structure before and after jacking and after reinforcement, it can provide some guidance for the design and construction of the whole structure jacking.
