The numerical simulation on dynamic response of Tibetan traditional stone-wood structure under earthquake action

Based on the existing test data obtained from preliminary study, the numerical modeling work for the characteristics of Tibetan traditional Stone-wood structure was performed in this paper. The mode of vibration and frequency were researched by modal analysis method. Meanwhile, the time history curves of displacement at different parts of structure and peak displacements were obtained after simulating the dynamic response of structure under frequent earthquakes. And the weakest parts and damage characteristics under the frequent earthquakes have been summarized. Studies showed that the shapes of displacement curves at different parts of structure were so similar that the displacement of all components reached to the peak at the same time. Finally the weakest parts of Tibetan Stone-wood structure were parapet walls with the largest peak displacement under earthquake and walls near to structural opening were easier to be destroyed than others.
