Study of Ultimate Displacement of Timber Structures in Chinese Ancient Buildings

The available methods to determine the ultimate displacement of the building structures have been put forward, and the disadvantages of the methods are analyzed. According to the seismic design theory based on displacement of structures and reinforcement standard of Chinese ancient architecture, which refers to the modern structural engineering requirements, the ultimate displacement of the timber structure on Chinese ancient buildings, which is under the obvious P-Delta second-order effects, has been studied. The ultimate displacement and the drift ratio limit value of different axial compression ratio are determined by the experiments and Theoretical calculation. The results of the study of ultimate displacement can provide the technical support for the rehabilitation of the ancient timber buildings.
