A temple is not considered to be capable of resisting large earthquakes because of its poor resistant wall and heavy roof. In this paper, we propose a simple analytical model on a temple and estimate it's paremeters taking the case of four temples standing at Shizuoka prefecture in order to obtain the dynamic response during earthquakes. The main results obtained from this sudy are as follows. An one-side eccentric axis model considering the sway and rocking deformation of soil-structure system could represents the dyanamic characteristics of temples. In this model, mud-plastered wall and column which has rotational stiffness at each end of it are horizontal resistant factor. The paremeters of mud-plastered wall are decided from the results of experiments. The rotational stiffnesses are evaluated as 10,000 kN.m/rad depending on coincidence of the natural frequency of analytical model with that of existing temple. These walls and columns are considered to be connected as parallel.
