An analysis model construction method and analysis model construction system for seismic safety evaluation of a bridge are disclosed. In the analysis model building method according to an embodiment of the present invention, when an evaluation request regarding seismic safety of a bridge according to an earthquake is received, an input earthquake input to the bridge is used to determine the structure of the bridge after the earthquake. Calculating a state data relating to the data; constructing the seismic analysis file for the bridge by combining the state data; and outputting the seismic analysis file in response to the evaluation request; The calculating of the data may include: analyzing the structure of the bridge according to a finite element analysis method, constructing an analysis model, maintaining the analysis model in a database in association with the model information of the bridge, and According to the model information of the input bridge, the input earthquake is applied to the analysis model retrieved from the database. And a step of calculating the state data.
