Abstract

In this study, 7 different rapid evaluation methods which are used to determine the performance of buildings under the influence of earthquakes in a fast and practical way are examined. These methods were used to determine the earthquake performance behaviors (risky or safe) of buildings according to each method by using the parameters of 50 buildings that were collapsed or severely damaged in Van earthquake that occurred in 2011. Accurate estimation percentages of the methods on the buildings were calculated by comparing the obtained earthquake performance behaviors with the current situation of the buildings. The most suitable method has been tried to determine for 50 buildings related to these calculations. At the same time, a computer program called EPA (Earthquake Performance Analysis) was developed in order to evaluate the parameters of the related data set faster, easier and without error. Three of the 7 rapid assessment methods used to determine the earthquake performance behavior of buildings are first-stage methods called street screening (6306 RYY, FEMA P-154 and Sucuoğlu and Yazgan level-1), and the remaining four methods are second-stage methods called pre-assessment (Sucuoğlu and Yazgan level-2, Özcebe, Yakut and MVP). According to the results, the pre-assessment methods predicted the earthquake performance status of the buildings examined by 24% higher than the street screening methods. At the same time, the most successful method of street survey methods was 6306 RYY with 74% accurate estimation, and the most successful method of preliminary assessment with 86% accurate prediction was Yakut method.
