Abstract
Çelik plakların düzgün yayılı yük altında davranışı incelenmiştir. Plakların yayılı yük altındaki sehim miktarları deneysel olarak tespit edilmeye çalışılmıştır. Kren konstrüksiyonunda kullanılan çelik levhalarla ilgili fazla deneysel çalışma bulunmamaktadır. Tez başlığıyla her ne kadar kren konstrüksiyonuna gönderme yapıldıysa da, bu çalışmanın çelik plakların kullanıldığı diğer alanlar için de faydalı olacağı umulmaktadır. Tezde önce ilgili literatürdeki sayısal çözümlere değinilmiştir. Plak numunelerinin ankastre mesnetlenebileceği bir deney düzeneği tasarlanmıştır. Deney masasına bağlanan çeşitli kalınlık ve boyuttaki levhalar üstüne yayılı yük uygulanmıştır. Çökme değerleri levhaların yüzeyine yapıştırılan gerinim pulları (strain gage) aracılığıyla tespit edilmiştir. Gerinim pulları analog-dijital dönüştürücü özellikli veri toplama sistemine bağlanarak, alınan sinyaller bilgisayar ortamında işlenmiştir. Toplanan tüm deneysel veriler, daha önce konuyla ilgili literatürde yapılmış sayısal çözümler ile karşılaştırılmıştır. İleriye dönük öneriler sunulmuştur.
The behaviour of steel plates under uniformly distributed load were investigated. The deflection of plates under distributed load were determined experimentally. There is not much experimental work on steel plates within crane structures. Although, the created thesis title refer to crane structures, this study is expected to be useful for other areas that steel plates are being used. Firstly, the numerical solutions which amongst the related literature has been cited. A test mechanism has been designed in order to clamp the various plate specimens. Experiments on various thicknesses and sizes of plates were carried out by applying uniform load. The deflections were determined through using strain gages bonded on the surface of the thin plates. Strain gages were connected to a data acquisition system featuring an analog to digital converter, and received signals are processed in computer environment. All of the collected experimental data were compared with numerical solutions, made earlier in the literature on the subject. Future recommendations are presented.
