英文摘要： The object of this project is the building structure with traditional Chinese architectural style which is constructed by different structural systems, i.e., steel reinforced concrete structure, of which the structural performance is thoroughly studied. Subsequently, the structural vibration con-trol technology and analytical procedure are researched by means of vibration control theory. After the collection of materials related to modern pseudo-classic architecture, a composite-structure building is preliminarily designed based on the structural configuration of ancient timber buildings and material performance of composite structures. The low cyclic loading tests are conducted on beam-to-column joints and Dougong sets which are made of steel reinforced concrete structure, steel structure and composite structure. Then a mechanical analysis model for the joint and Dou-gong set is developed respectively by means of experimental study and finite element analysis. The vibration control design is carried out based on modern vibration control theory, and the low cyclic loading tests are conducted on beam-to-column joints and Dougong sets which are equipped with vibration control devices. Vibration control calculation and analysis method of the joint and Dougong set for different structural systems is put forward via
