축력을 받는 석벽돌 적층모형의 고유진동수 = The Natural Frequency of Multi-layer Masonry Structural System on Axial Force

다국어 초록 (Multilingual Abstract)

When surveying the cultural heritage, preserving their original state is of primary importance, one must consider non-destructive method first. And when analyzing or modeling the stone masonry structures, one should know the stiffness of structural system. Dynamic characteristics of stone masonry structures depend on several factors such as coefficients of friction, contact conditions and number of layers of bonding stones. So. one can estimate the stiffness and robustness of structural system by analysing the dynamic characteristics. This paper describes a natural frequency of arch shaped structures. For this purpose, granite brick models of multi-layer were made and fundamental frequencies were measured as increasing of axial force. The natural frequencies were increased as increasing of axial force. With these results. it may be assumed that the vibration modes of stone masonry structures are influenced by rocking.
