Abstract

It is historically a fact that Turkey experiences frequent earthquakes, on the order of one damaging earthquake of magnitude 6–7 approximately every 2 years, causing extensive losses to economy, life and limb. Every strong earthquake leaves behind poverty and tens of thousands of homeless people. In order to mitigate especially the losses of life due to earthquakes, a rapid scoring technique called the P25 – Preliminary Assessment Method is proposed herein. The purpose of the method is to determine, for a reinforced concrete-framed building, whether there is any vulnerability to collapse during a strong earthquake. By identifying those buildings, which are most likely susceptible to collapse inside a particular building stock, and consequently strengthening or demolishing them, practically no loss of life will occur. In this presentation, details of P25 – Preliminary Assessment Method are discussed and the high degree of prediction reliability of the method is demonstrated on 323 case study buildings, which experienced wide ranges of damage during past earthquakes.
