“…The nonlinear analysis approaches differ according to (1) the type of employed method of analysis: nonlinear static (pushover) and/or time-history (Casolo 1998;Bernardeschi et al 2004;Girardi et al 2010;Peña et al 2010;Milani et al 2012;D'Ambrisi et al 2012;Casolo et al 2013;Salvatori et al 2015). The pushover methods comprise both standard (Milani et al 2012;Casolo et al 2013) and multimodal approaches.…”

This paper focuses on the seismic risk assessment of historic masonry towers according to the Italian "Guidelines for the Assessment and Mitigation of the Seismic Risk of the Cultural Heritage." The latter identifies a methodology of analysis based on three different levels of evaluation, according to increasing requirements on the structural knowledge: LV1 (analysis at territorial level), LV2 (local analysis), and LV3 (global analysis). Regardless of the methodology of analysis, the more advanced the achieved level of knowledge, the higher the reliability of these approaches becomes. In this field, a fundamental task is the estimation of the uncertain parameters (both material properties and boundary conditions) affecting the structural behavior. The effect of these uncertainties on the global structural response is herein approached through the discussion of an illustrative case study of some of the historic masonry towers in the city center of San Gimignano (Siena, Italy). The seismic risk of these towers was analyzed in the framework of Seismic Risk of Monumental Buildings (RiSEM is the Italian acronym), a research project granted by the Tuscany Regional Administration, and this paper summarizes the results obtained for two of the preceding three levels, which highlights a few issues concerning the seismic risk of historic masonry towers. Useful conclusions are drawn in order to quantify, when performing an LV3 approach through nonlinear models, the effects of the uncertainties on the seismic risk evaluation of such structural typology. The paper, in particular, confirms once more how strongly the effect of confinement reflected on tower seismic performances and stresses that specific attention should be paid to the definition of the effective portion of the structure to be considered as confined (with respect to adjacent buildings).

“…The target of these studies were mostly to (1) control the accuracy of the analytical modelling of the bridge to use it during the life span of the bridge and/or (2) carry out a long term monitoring under service loads (AbdelGhaffar and Scanlan 1985;Chang et al 2001;Hiesh et al 2006;Huffman et al 2006;Gentile and Gallino 2008;Picozzi et al 2010;Apaydin et al 2012). Furthermore, in case of identifying the dynamic characteristics of cultural heritage structures, vibration-based methods are of vital importance since these methods respond to the preservation needs of these types of structures (Ivorra and Pallares 2006;De Stefano 2007;D'ambrisi et al 2012;Foti et al 2012;Asteris et al 2014;Votsis et al 2012;Chrysostomou et al 2005Chrysostomou et al , 2008. Besides, in the case of RC structures, vibration-based methods are among valid tools for predicting the behavior of these structures during earthquakes (Brownjohn 2003;Nayeri et al 2008;Herak and Herak 2010;Michel et al 2010;Celik et al 2013).…”

In this study, forced vibration tests were conducted on two full-scale substandard reinforced concrete (RC) buildings to obtain the dynamic characteristics (modal frequencies and damping ratios) of these buildings. These tests were carried out before and after quasi-static lateral loading cycles. Through quasi-static cyclic loading, which was applied only in x direction of the buildings, the buildings were forced to experience specific damage states in a controlled manner. The original aspect of the study is investigating the rates of changes of the dynamic characteristics with the increasing damage. According to the test results, it was observed that modal frequencies tend to decrease while damping ratios for different modes tend to increase with the increasing levels of damage. In addition, finite element models of the buildings were established and modal analyses were performed for the undamaged state. Model updating was carried out in order to determine the optimal means of improving the accuracies of the finite element models of the test buildings. Experimentally identified modal frequencies of the buildings and those computed using finite element model were found to be consistent. Since the buildings tested in this study represent most of the existing substandard RC buildings in Turkey, determining the changes in dynamic characteristics with the increasing damage would be useful in the decision of demolishing/retrofitting of these types of buildings after potential future earthquakes.

The interaction between soil and structure plays a crucial role on accurate determination of structures' seismic behavior. The assumption of fixed base structure has been commonly used in traditional design works, and the interaction between soil and structure is thus often neglected. In addition, historical masonry structures particularly built on elastic soil media may be significantly affected seismic behavior of the structure under earthquakes. In this research, the damage distribution on a historical masonry minaret is numerically investigated under horizontal earthquake ground motion. AlacaMosque minaret was built in 1271 in Bolvadin district of Afyon province. The historical masonry minaret was chosen as the subject of the study. Nonlinear seismic time history analyses were conducted for fixed-based and different soil properties under horizontal earthquake ground motion. The horizontal (East-West) component acceleration records of Dinar earthquake (Mw = 6.1) that took place on October 10, 1995, were used during the analyses. Maximum displacement, maximum/minimum principal stresses, and damage ratios were determined by nonlinear analyses performed considering fixed base and soil-structure interaction. The analysis results showed that soil-structure interaction had significant effect on the structural behavior of the minaret, such that, the minaret that was expected to get damage in the case of fixed base did not get any damage when soil-structure interaction was considered.
