Study on Vibration Character and Dynamical Response of Shen-Wu Gate in the Forbidden City in China

摘要：

Ancient buildings in China are mainly made of wood which have the character of earthquake resistance.The Shen-Wu Gate in the Forbidden City is an good example.Considering constitutions such as Tenon-Mortise joints,Tou-Kung ,Cejiao and so on ,its finite element model is built.Modal as well as dynamical analysis are carried out to study vibration characters and dynamical responses of the structure.Results show that the base frequency of Shen-Wu Gate is 1.07Hz,its main vibration modes focus on 1st ,2nd and 9th in x,z and y directions;Under three-direction seismic forces (peak acceleration value reaches 400g) the structure responses with large deformation and acceleration values but remains stable.
