In order to protect the murals in Daxiong Palace in Jiange County,Sichuan Province,damage caused by the Wenchuan earthquake was analyzed.Base on survey results made after earthquake,typical damage characteristics of the murals were discussed.The results demonstrate that the Cejiao constitution concepts used in Chinese ancient buildings has helped to resist earthquakes.Considering the mural strengthening techniques as well as the characteristic mortise and tenon joints typical of Chinese ancient buildings,a finite model of Daxiong Palace was built.In order to simulate damages to the mural paintings under the Wenchuan earthquake conditions,modal analysis was done and then the Wenchuan waves were amplified and imposed on the model.By doing dynamic analysis,peak values for displacements as well as inner forces of the structure under simulated Wenchuan earthquake conditions were obtained.Response curves for selected typical nodes were obtained.Results show that main cause of damages to the murals occurred because they were not fixed tightly to the base layer of the wall,which led to tensile strength failure. Under Wenchuan earthquake condition,the murals kept vibrating constantly;In order to enhance aseismic capability of the murals,isolation materials have to be filled between the wooden frames and the outer wall plates.Connection between wall and wooden frames has to be strengthened.Daily maintenance of the murals is also a very important factor.
