“…The higher modes relating to the mosque revealed a remarkable difference of required and measured frequencies. This difference indicates that the model was "softer" than required and could be considered as an "adequate" model with reduced strength characteristics, approaching a "partially true replica" model [Krstevska et al, 2010]. …”

“…The model was built using the same materials and techniques as in the prototype and according to the gravity forces neglected approach. The results of the experimental investigation are presented in a separate article [Krstevska et al, 2010]. The adopted physical model is suitable for structural configurations in which the stresses induced by gravity loads are negligible if compared to stresses induced by seismic actions, as in the case of the mosque.…”

A finite element analysis was carried out to assess the seismic behavior of Mustafa Pasha mosque in Skopje and the efficiency of a CFRP-based strengthening technique. The numerical models of the as-built and retrofitted mosque were calibrated and validated against the results of an extensive experimental investigation based on shaking table tests on a large-scale physical model. Linear dynamic and nonlinear static analyses were performed to design the retrofitting intervention and to analyze the seismic behavior of the large-scale model before and after strengthening. Experimental and numerical results were compared to assess the accuracy of the models. The formation of crack patterns observed on the large-scale model in the different phases of the testing program was analysed and the responses to lateral load were compared. Finally, the numerical models were used to predict the seismic behavior and the effectiveness of the retrofitting system on the full-scale prototype

“…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.

“…Nevertheless, stresses due to gravity loads would be smaller than those of the prototype by one times the geometric scale factor. This partial compliance with the laws of similarity has been called “simple model similarity” by Tomaževič and Velechovsky (1992) and has frequently been adopted in shaking table tests of masonry structures (i.e., Gavrilovic et al 1999, Krstevska et al 2010). We considered that, because the expected modes of failure involved out-of-plane bending and in-plane diagonal tension, the response of the model would be significantly affected by differences in stresses due to gravity loads; therefore, the model was designed and tested as a full-scale miniature temple.…”

This paper reports the results of the second phase of a research program that carried out shaking table tests on a scale model of a typical stone masonry temple. This second phase evaluates the efficacy of two different retrofitting techniques by comparing the response of the retrofitted models with that of the original unreinforced model. It was found that both retrofitting schemes substantially enhanced the performance of the model temple. The maximum intensity of the base motion for which damage was considered to be still repairable increased by 80% and 120% for the first and the second levels of retrofitting, respectively. In terms of displacement capacity, the response of the model with the second level of retrofit reached a maximum drift of 0.4%. The initial damping ratios were found to be in the range of 7% to 9%, both in the original and the retrofitted models. These ratios constitute a significant source of energy dissipation for this kind of structure.
