Risk analysis of selected buildings in Shahrekord based on HAZUS requirements using fuzzy logic

Earthquake is a natural and unpredictable phenomenon that causes a lot of human and financial losses in many seismic zones of world. Therefore, the prediction of seismic events is one of the most important in earthquake and structure literature. Moreover, planning for crisis prevention as well as taking appropriate decisions after the crisis in urban areas will significantly increase the impact of measures to reduce the seismic risk. One of the computational tools in the risk analysis is the fuzzy logic to predict the possible damages due to natural disasters. Precise scientific principles and many advantages of this tool in analyzing phenomena with probabilistic uncertainties have caused its application to be constantly expanded and developed. In the present paper, the use of fuzzy tools for classification of the structures in Shahrekord (IRAN) has been investigated and the seismic hazard of selected buildings in this city is examined as a sample of existing structures. The results are consistent with the experiences of the recent earthquakes in this country for the vulnerability of buildings in urban areas. Also, the results indicate that the proposed method has good adaptation and the parameters which have been used in the damage assessment, propose good reliable flexibility.
