Çubuk Ağı Ahşap Kubbeler

ÖzGeniş açıklıklı yapı ihtiyacına yönelik tasarım anlayışının, 20. yy’ın başlarından itibaren kendini gösterdiğisöylenebilir. Bu anlayışta, malzeme, biçim ve taşıyıcı sistem bir bütün halinde değerlendirilir ve tasarıma katılır.20.yy’ın ikinci yarısından itibaren gelişen lamine ahşap kompozit eleman (glulam) üretim teknolojileri, genişaçıklıklı ahşap yapı tasarımını mümkün kılmıştır. Bu çalışmada çubuk ağı kabuk sistemler genelinde; önemlibir uygulama alanı bulan tek tabakalı ahşap kubbeler incelenmektedir. Malzeme, form ve taşıyıcı sisteminverimliliği, bilinen en geniş açıklıklı ahşap kubbe örnekleri üzerinden karşılaştırmalı olarak irdelenmektedir.Kubbe maliyetine etki eden parametrelerden biri taşıyıcı sistemin tipi ve basıklığıdır, jeodezik sistem ekonomikliğiile tercih edilmektedir. Birleşimlerin teşkil biçimi ve yükleri taşıma kapasitesinin yanısıra; kubbe yüklerininzemine aktarılma biçimi de önemlidir. İncelenen örneklerden, yüklerin payandadan çekme çemberine aktarımbiçiminin en uygun çözüm olduğu görülmektedir.
