Precast corbels are commonly preferred structural members in industrial
buildings. In this study, a novel application of support vector machines (SVM)
is employed for the prediction of ultimate shear strength of fiber reinforced
corbels, for the first time in literature. SVM models are developed and analyzed
using a database of available test results in literature. Predictions of the
selected model are compared against the test results and those of available
model proposed by Fattuhi (1994). Proposed model has the capability to predict
the shear strength of both steel fiber reinforced concrete (SFRC) and glass
fiber reinforced concrete (GFRC) corbels. Additionally, a parametric study with
a wide range of variables is carried out to test the effect of each parameter
on the shear strength. The results confirm the high prediction capacity of
proposed model.

Lifli Betonarme Kısa Konsolların Kesme Dayanımının Destek Vektör Makineleri ile Tahmini

Öz

Prefabrik kısa konsollar, özellikle sanayi
yapılarında sıkça tercih edilen yapı elemanlarıdır. Bu çalışmada, lifli
betonarme kısa konsolların kesme dayanımı, literatürde ilk defa, destek vektör
makineleri (DVM) ile tahmin edilmiştir. Mevcut deneysel veriler kullanılarak
DVM modelleri oluşturulmuş ve tahmin performansları analiz edilmiştir. Seçilen
modelin tahminleri, deney sonuçları ve literatürde mevcut olan modelin
(Fattuhi, 1994) tahminleri ile karşılaştırılmıştır. Model, çelik lifli kısa
konsolların yanı sıra cam lifli konsolların taşıma kapasitelerini de tahmin
edebilmektedir. Ayrıca model, her bir girdi parametresinin etkisini incelemek
amacıyla, parametrik analize tabi tutulmuştur. Sonuçlar, önerilen modelin yüksek tahmin
kapasitesine sahip olduğunu göstermektedir.
