Empirical Equations for Estimation of the Fundamental Vibration Frequency of Historical Masonry Towers

Historical buildings are valuable structures. Therefore, performance evaluation of these structures under different loadings such as seismic effects has been considered in several research projects in recent years. Masonry towers are known as one of the common types of historical structures that exi...

description	Historical buildings are valuable structures. Therefore, performance evaluation of these structures under different loadings such as seismic effects has been considered in several research projects in recent years. Masonry towers are known as one of the common types of historical structures that exist in different countries. To evaluate the seismic performance of masonry towers, their dynamic properties are needed. Among the dynamic characteristics of the towers, fundamental vibration frequency is known as the most important one. In this regard, formulations for estimation of the vibration frequency of these structures in useful. For this purpose, a database consisting properties of 38 towers which were identified through in-situ dynamic tests or numerical analysis before, are collected.
