“…For that purpose, the model of the Mustafa Pascha mosque that was damaged during the Skopje earthquake of 1963, Figure 12(a) was built [ Figure 12(b)]. In a similar way as that used for the cathedral, the non-damaged model was tested first and once the damages were defined, the model was strengthened (Portioli et al, 2011;Sendova et al, 2008;Krstevska et al, 2009). The strengthening consisted of incorporation of horizontal belt courses.…”

Traditionally, most historic buildings represent pre-21th century masonry structures. It is due to the extensive presence of such masonry structures that their behaviour under earthquakes will be analysed in this paper. First, this paper will outline the traditional methods and materials used in the construction of historic masonry structures. Second, a typical damage scenario will be described showing what happens when these historic structures are subjected to earthquakes. Reference will also be given to damage suffered by historic buildings under the latest catastrophic earthquakes in L'Aquilla, Haiti and Chile. The traditional, standard methods for repair are discussed. Then, the principles of the base isolation theory and the current hardware used for isolating structures is presented. Next, a time-history analysis of a historic masonry church is discussed, comparing the response of a fixed-base versus an isolated church. Finally, a review of the IZIIS' activities related to protection of historic buildings against earthquakes is given. It is concluded that base isolation is very applicable in retrofitting of historic buildings since it drastically reduces the seismic forces and enables protection of these structures by minimal interventions.

“…Various numerical techniques and models with different complexities and accuracies for the static and dynamic analysis of masonry structures are presented [1][2][3][4][5][6][7][8][9][10][11]. Different methodologies for the structural restoration of historical buildings are described [12][13][14][15]. e acquired experience on the analysis and strengthening of numerous buildings in Italy after the recent earthquakes were also useful for this study [16][17][18][19][20].…”

Firstly, some important aspects of the restoration and structural strengthening of historical masonry buildings are briefly discussed. Particularly, as an illustration of the appropriate approach to solving such an issue, an example of the restoration of the Minceta fortress in Dubrovnik has been described. Based on the results of the extensive field and laboratory works with defined damages and cracking state in the fortress, as well as located sliding surfaces in foundation rock near deep excavation, the static and dynamic analysis of stress-strain states and safety was performed at the characteristic time point in the history of the fortress. Different geometry models for discretization of the fortress and the foundation rock, as well as different constitutive models for masonry and rock, were considered. Based on the results of the case study, the solutions were proposed for the strengthening of the foundation rock, as well as for the restoration and the limited allowed strengthening of the fortress. It is believed that this study may be helpful in the restoration and strengthening of similar historical masonry structures.

“…Finite element analysis was carried out to assess the seismic behavior of the mosque and the efficiency of a carbon-fiberreinforced polymer-based strengthening technique. Gang et al [14] studied about the seismic reliability of Guang Minaret in frequently occurred earthquake to see if it met the reliability criterion demand. Oliveira et al [15] performed a series of in situ ambient vibration tests to old minarets of various sizes and compared results of frequencies with numerical modeling of the same structures.…”

Minarets are one of the specific structure types used commonly in Islamic Countries. Many minarets were damaged or collapsed during catastrophic events like earthquake. During an earthquake to understand the minarets' behavior are so important since dynamic response of these structures depends on a detailed understanding of their structural characteristics, such as geometrical shape, supporting system, mode shapes, natural frequencies and modal damping ratio etc. This paper examines in detail a Turkish style reinforced concrete (RC) minaret, its finite element modeling, modal analysis and earthquake analysis. A reinforced concrete minaret which is generally built in Turkey is selected as an application. Three-dimensional (3D) model of the minaret and its modal analysis are performed to obtain analytical frequencies and mode shapes using ANSYS finite element program. The minaret's linear transient analysis is carried out using the 1992 Erzincan earthquake ground motion record to obtain the earthquake behavior of the minaret. At the end of the study, the calculated displacement responses and maximum-minimum principal stresses concentrations for the minaret are briefly discussed and illustrated.
