Abstract

Bu çalışmada
AASHTO-LRFD Köprü Şartnamesinde uygulama ve hesap özellikleri verilen hareketli
yük dağıtma katsayılarının (LLDF) köprülerin analizinde kullanılması
araştırılmıştır. Bu amaçla, üç açıklıklı 30-30-30 m ve 33-50-38 m köprülerin
LLDF hesaplamaları AASHTO Şartnamesine göre yapılmıştır. Bu köprüler yaklaşık
analiz yöntemi olan Çizgisel-Kiriş yöntemiyle analiz edilmiştir ve hesaplanan
LLDF katsayıları analizde kullanılmıştır. 30-30-30 m köprünün SAP2000
programıyla ve 33-50-38 m köprünün CSiBridge programıyla analizi yapılmıştır.
Bu programlarla yapılan analizde LLDF katsayıları program tarafından otomatik
olarak hesaplamalara katılmaktadır. 
Yapılan çalışma sonucunda Çizgisel-Kiriş yöntemiyle analizden elde
edilen sonuçların, hassas ve kesin analiz yapan SAP2000 ve CSiBridge
programlarıyla elde edilen sonuçlara çok yakın olduğu görülmüştür. Böylece, AASHTO
Tasarım Şartnamesi’ne göre LLDF hesaplamalarının yapısal analizde kullanımının
doğruluğu ve uygunluğu ortaya konulmuştur.
