AHŞAP-BETON KOMPOZİT DÖŞEMELERİN BİNALARDA VE KÖPRÜLERDE KULLANIMI ÜZERİNE BİR İNCELEME

Öz

Bu çalışma ahşap-beton kompozit döşemelerin binalarda ve köprülerde uygulanma olanaklarını sunmaktadır. Ahşap-beton kompozit sistem bir yapım tekniğidir. Ahşap-beton kompozit döşeme bazı bağlantı teknikleri kullanılarak ahşap kirişler ve bir beton plak ile oluşturulan bir sistemdir. Bu sistemde ahşap ve beton elemanların strüktürel performansı büyük ölçüde kompozit davranışın özelliklerine bağlıdır. Bu tür kompozit sistem çoğunlukla Amerika Birleşik Devletleri, Avustralya ve Avrupa ülkelerinde tercih edilmektedir. Ahşap-beton kompozit döşemeler mevcut ahşap binaların döşemelerinin yenilenmesinde, yeni bina yapımında ve köprü yapımında kullanılmaktadır. Türk inşaat sektöründe ise kullanılmamaktadır. Bu nedenle, bu çalışmanın amacı inşaat uygulamalarında kullanılan ahşap-beton kompozit sistemi incelemektir. Bu amaçla, bu tür kompozit sistemin strüktürel tasarım ve yapım özellikleri ilgili literatür analiz edilerek ortaya çıkarılmaktadır. Bu çalışmada binaların ve köprülerin yapımında kullanılan ahşap-beton kompozit döşemeler incelenmektedir ve uygulama örnekleri sunulmaktadır.
