Abstract
The dynamic behavior of multi-layered stone masonry monuments, such as stone pagoda, are mainly influenced by contour condition of contacting surface of stones. These structures can be modeled as a multi-degrees of freedom system. In this case the mass of the system can be easily estimated, mean while the estimation of stiffness at junction is not simple. In this paper a method for estimating the spring constant at the contacting surface of stone is proposed. The proposed method utilizes the natural frequency of the system which can be obtained by eigenvalue analysis.
