A survey of subjective opinions of population about seismic resistance of residential buildings

Abstract

The unpredictability and the seriousness of the potential earthquake consequences for people and residential buildings in Serbia imply the need for improving the resilience of local communities. The paper presents the results of a quantitative research regarding the level and factors of influence on the awareness of citizens about the seismic resistance of their residential buildings to earthquake consequences. Multiple-point random sampling was used to survey 1,018 citizens (face to face) during 2017 in 8 local communities: Kraljevo, Lazarevac, Jagodina, Mionica, Prijepolje, Vranje, Lapovo and Kopaonik. The questionnaire consisted of two segments: questions on demographic, socio-economic and psychological characteristics of respondents and questions regarding resistance of residential buildings to earthquake consequences. The results show that 35% of respondents state that they live in residential buildings that are not resistant to earthquakes, while 70.7% state that they live in buildings built of reinforced concrete, which are considered safe. Beside that 9.2% of respondents examined the resistance of their facilities to earthquake consequences. Inferential statistical analyses show that men to a greater extent than women state that their buildings are resistant to earthquake consequences. Starting from the multidimensionality of citizen vulnerability to earthquakes, it is necessary to conduct additional studies and further elucidate the sociological dimension of vulnerability and resilience.
