Research on the Effects of Structural Characteristics on the Mechanical Performance of Zhutou Puzuo in Yingxian Wooden Pagoda
The Zhutou Puzuo joint is an important component of the Yingxian wooden Pagoda. Study on Puzuo’s seismic performance for the protection of the Yingxian wooden pagoda is of considerable practical importance. The impact of structural characteristics on the seismic performance of the Zhutou Puzuo is the focus of this paper. The Zhutou Puzuo models at 3rd to 5th storey open-layer outer floor are tested by quasi-static cyclic test. Results show that the more the number of Pu of the models with varied structural characteristics are, the stronger the energy dissipation capacity and the greater the horizontal bearing capacity are. In positive loading, rotational deformation is the predominated deformation in the Zhutou Puzuo, while both rotational and slip deformation predominate in negative direction. The proportion of slip deformation of components decrease with the increasing the number of Pu. In the negative loading, the proportion of slip deformation increases when the number of Pu decreases. However, negative slip deformation increases dramatically when the ears of Sandou or Qixindou between two adjacent layers are sheared. The maximum proportions of slip deformation of DG-1, DG-2 and DG-3 accounts for 51%, 47% and 87% respectively. The sliding components of the Zhutou Puzuos at 3rd to 5th story are primarily located in the middle and upper portions of the model. The research can give a solid basis for the safety and rehabilitation of the Yingxian wooden pagodas.
