KOLON KESİT PARAMETRELERİNİN PREFABRİK SANAYİ YAPILARININ HASAR GÖREBİLİRLİĞİNE ETKİSİ

Öz

Bu çalışmada Türkiye’deki tek katlı prefabrik sanayi yapıları için hasar olasılık eğrileri analitik yolla elde edilmiştir. Kolon kesit parametrelerinin hasar görebilirliğe etkisinin değerlendirilebilmesi amacıyla kolon boyutu, boyuna donatı oranı, etriye aralığı parametrelerine bağlı olarak 8 tipik prefabrik sanayi yapısı modeli kullanılmıştır. Doğrusal ötesi zaman tanım alanında analiz için 28 depreme ait 360 ivme kaydı seçilmiştir. Yer hareketi parametresi olarak lognormal dağıldığı kabul edilen PGV seçilmiştir. Yapısal tepki parametresi olarak kritik kesitte beton ve çeliğin birim şekil değiştirmelerine bağlı olarak hesaplanan yatay deplasman kullanılmıştır. Seçilen parametrelerin, prefabrik yapıların hasar görebilirliği üzerinde etkili olduğu belirlenmiştir

Effect of Column Section Parameters on Fragility of Precast Industrial Buildings

Öz

The aim of this study to obtain analytical fragility curves for precast industrial buildings in Turkey. In order to determine the effect of column section parameters on fragility curves, 8 typical precast buildings are considered according to column section, longitudinal reinforcement ratio and stirrup spacing. 360 ground motions, selected from 28 different earthquakes, are used for nonlinear time history analysis. Using the structural response parameters and ground motion parameter PGV, fragility curves are constructed assuming two-parameter lognormal distrubition. Lateral displacement is selected as structural response parameter. Fragility curves are suggested for immediate occupancy, life safety and collapse prevention damage levels. Results show that, concerned parameters affect fragility of precast industrial buildings

Anahtar Kelimeler
