Based on extensive investigation of construction technique history of chinese ancient buildings, the structure method, structure developing history and seismic behavior of chinese ancient timber structure buildings are analyzed in several respects of the structural system and form. through a series of experiments on constituent parts of chinese ancient timber building structure, including the tests on the corbels and brackets called dougong subjected to low cyclic reversed loadings, the tests on the wooden frame using the tenon - mortise joints as connections of column and beam subjected to low cyclic reversed loadings, the tests on vibration isolation effect of friction and slippage between column footing and their socle base, and a series of shaking table tests on a chinese ancient timber structure palace building mode under artificial earthquake at serving conditions, destroyed conditions and reinforced conditions, many valuable results of structures such as moment - curvature hysteretic loops of dougong structure and tenon - mortise joints under low cyckc reversed loadings, the static function, the seismic performance, energy dissipation, vibration reduction, energy - loss mechanism, nechanicalmode and failure mode were studied. aplenty of valuable parameters of the structure system were obtained, such as the natural period of structure, vibration modes, damping ratio, factor of vibration isolation, oscillate amplitude of ineitial accebration, velocity and displacement, magnitude of slippage, and the mechanism of structure failure and collapse etc. based on these research, the complete analysis of ancient timber structure under earthquake were carried out in which including mechanism analysis method, calculating mode, strength analysis of members and joints, strengthening methods for serving damaged ancient timber structure buildings were also taken into account
