INTRODUCTION
Identification of dynamic characteristics of structural systems is an important step that is necessary for two basic reasons: − to assess possible dynamic behavior of structures during strong events and − to gain experience on the general dynamic characteristics of structural systems such that the experience and data base can be used in future design and analyses. Past efforts in determination of dynamic characteristics of structures has facilitated development of data bases, which in turn has been used in establishing empirical formulas for estimation of fundamental periods of structures in design codes. Also, critical damping percentages used during dynamic analyses are obtained from past data bases. The data bases for dynamic characteristics of building structures are sufficiently populated. However, data on dynamic characteristics of special structures such as bridges and in particular cable-stayed bridges are scarce.
