To effectively protect ancient Chinese buildings, based on the research achievements of an earlier paper, Shaking table tests of an ancient Chinese building with single layer gable and hip roof, the seismic performance of a model was studied under conditions of high-intensity earthquakes. The same model with the one in the first paper was built, and waves in horizontal directions, simulating the 1940 El-Centro earthquake, were applied to the model, with the intensity gradually being increased to a very high level. Experimental phenomena of different constituents of the model were analyzed and symptoms of damage were also investigated in detail. The results show that under high-intensity earthquake conditions, the column structure, the tou-kung, the beam system and the roof vibrate as synchronous motion as a slow sway. The main damage symptoms of the structure include deviation of column roots from their original positions, tenons being pulled out of mortises, cracks on tenon-mortise joints, deviation of parts of tou-kung from their origin positions, disconnection of the tie beam from its cushion board and collapse of filler walls, etc. However, the damage was not serious, nor did the timber structure collapse. The seismic performance of an ancient Chinese building under high-intensity earthquakes relates closely to its constituent characteristics.
