Improving the seismic resilience index of a school building

The aim of the seismic resilience of a structural system is to prevent, minimize or decrease the damages (loss of life, social, economic, structural, and non-structural damages) that occur due to earthquakes. The seismic resilience of structures is one of the most interesting topics in the fields of earthquake and structural engineering. The meaning of the word 'resilience' differs from field to field, but in earthquake and structural engineering, resilience means keeping the functionality of a structural system after it has been damaged (Bruneau et al. 2003). A seismic resilience analysis of a school building in Milas, Mugla, a high-risk area in Turkey, is conducted. The current research focuses on examining pushover analysis, fragility curves, vulnerability curves, and functionality curves to evaluate the seismic resilience of the school building. The methodology for the assessment of the damage depends on HAZUS MH MR4 (2003), with the building modeled using SAP2000 software. Nonlinear pushover analysis is performed. Three different models are utilized to finally form the residence curve. It is examined the impact of these models on the resilience curves. The research is important in uncovering the effect of the models designed for utilization in the regional or building-based resilience analysis. Furthermore, it emphasizes the factors affecting the characteristics of the resilience curve. Consequently, this analysis aims to contribute to enhancing the attributes of the seismic resilience of school buildings or buildings with identical structural features.
