Abstract: In order to effectively protect Chinese ancient buildings, a model of single layer gable and hip roof type is taken as an example, based on experiment results, the finite element analysis are carried out to analyze its dynamic characteristic and seismic responses under 8-degree intensity of frequently occurred earthquakes. Based on hypothesizes that tenon-mortise joint and bracket sets are simulated by spring elements, and column roots are of free-standing status, finite element model of the experiment model is built. By modal analysis, its basic frequency and main modes are obtained; by time-history analysis under PGA=0.1g（x direction） of level earthquakes（x∶y=0.85∶1）, displacement and acceleration response curves of typical nodes, and internal force response curves of typical elements are obtained, seismic performances of the structure are discussed. Results show that basic frequency of experiment model is 1.34 Hz, its main modes are of translation; under earthquakes of 8-degree intensity of frequently occurred earthquakes, the structure vibrates steadily, whose peak displacement as well as internal force response values are within permitted scopes. Besides, the simulation results are in good agreement with those of the experiments. The results of this study can provide a theoretical basis for the performance evaluation and heritage preservation of single layer gable and hip roof type under frequent earthquakes, and provide a reference for the management of ancient buildings and relics.
