A REVIEW ON THE STUDY OF HISTORICAL STRUCTURES USING INTEGRATED INVESTIGATION ACTIVITIES FOR SEISMIC SAFETY ASSESSMENT. PART I: DYNAMIC INVESTIGATION

Assessment of seismic safety of historical structures is a challenging task because the information available about the assessed structure is usually limited. Therefore, it is often necessary to exploit a number of integrated investigation activities to increase the level of knowledge about the historical structure under consideration. Thus, in the case of any need for providing the structure with strengthening intervention, this intervention will be a minimal and any unnecessary strengthening operations will be avoided. This paper presents a literature review carried out to cover the current state-of-the-art of a number of investigation activities carried out integrally for the seismic safety assessment of historical structures. It is presented in two parts. In this first part, the covered topic is the dynamic investigation of historical structures which includes the dynamic identification tests, the dynamic monitoring, and the modal parameters identification methods with the classical and the advanced techniques like the peak picking and the stochastic subspace identification
