Abstract

Major damage and collapse occured, especially, in the public buildings, due to the earthquakes in Turkey. According to evaluations carried out after the earthquake, the main reason of damage situation is seen to originate from the structural deficiency. As is in the whole world, the building sector also requires costly investments in Turkey. Six percent of the Gross National Product is spent to building investments in Turkey. Because of this share reserved from the limited country sources, sufficient source to other investment sectors cannot be transferred. Consequently, the buildings that are for the use of  the public are needed to complement their productive physical service life by bringing them to resist against the earthquake. This study was carried out to establish an estimation of method for the source management in strengthening of school buildings which are public buildings. The cost of 11 different school buildings, which are within the Konya Province of Turkey and in the first degree earthquake zone and for which earthquake strengthening decisions are taken was found out, the supplementary reinforced concrete shear walls and column jacketing were determined by carrying out strengthening analyses of these schools and the construction costs of the strengthening was calculated. Concerning the estimation of the strengthening cost, the construction and strengthening costs were subjected to simple regression analyses. The outcomes have shown by using the construction cost that the strengthening cost can be estimated  with -0.0201% accuracy.

Key words: School buildings, earthquake, construction cost, strengthening, strengthening cost, regression analysis.
