Bu
çalışma, sarsma tablasında suni deprem yüküne maruz bırakılmış betonarme
çerçeveli dolgu duvarların düzlem-dışı deplasman, göçme modu ve göçme limitinin
yapay sinir ağları (YSA) modelleri ile tahmin edilmesini amaçlamaktadır. Bu
amaç için, sarsma tablasında yapılmış iki adet deney sonucu
değerlendirilmiştir. Model-I güçlendirmesiz tuğla duvarlı dolgu duvar numunesi,
Model-II ise tuğla duvarlarının arası derz donatıları ile güçlendirilmiş dolgu
duvar modeldir. Belirli bir ivme seviyesinden sonra duvar üzerinde çatlakların
oluştuğu yerlerdeki ivme ölçerler çıkarılmıştır ve veri kaybı oluşmuştur. Kayıp
olan düzlem-dışı göreli maksimum deplasman verileri YSA modelleri ile tahmin
edilmiştir. Ayrıca dolgu duvarın düzlem dışı davranışı boyunca oluşan göçme mekanizması
0,79g seviyesinde her iki model için tahmin edilmiştir. Bu çalışma, YSA temelinde
oluşturulmuş modellerin, kayıp verileri tam olarak tahmin ederek kesin sonuçlar
alınacağını kanıtlamıştır.
