Marmara depremlerinden bu yana on beş yıl geçtiği halde, maalesef İstanbul hala depreme hazır değildir. Beklenen M = 7.5 büyüklüğünde şiddetli bir deprem olursa, İstanbul’da en az 48 000 kişi ölür, 100 milyar doların üzerinde doğrudan ekonomik kayıp oluşur. Yöneticilerin iradesi ile, İstanbul’un kurtuluş reçetesi olan ‘Sıfır’ can kaybı projesi hiç vakit geçirilmeden bütün şehir sathında ve tüm ilçelerde derhal başlatılmalıdır. Yaklaşık 1.5 yıl sürecek ve 243 milyon dolarlık bir bütçe ile yürütülecek bu ‘sıfır’ can kaybı projesi bittiği zaman, şiddetli bir depremde İstanbul’da teorik olarak hiç kimsenin burnu bile kanamayacaktır
It is historically a fact that, Turkey experiences frequent earthquakes, on the order of one damaging earthquake of magnitude 6 to 7 at almost every two 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 of collapse during a strong earthquake. By identifying those buildings, which are most likely susceptible to collapse inside a particular building stock, and consequently by strengthening or demolishing them, practically no loss of life will occur. In this presentation, details of P25 - Preliminary Assessment Method are discussed and relatively high degree of predictability of the method is demonstrated on 323 case study buildings, which experienced wide ranges of damages during the past earthquakes
