THE ANATOMY OF THE WOODS OF THE HISTORIC DARAN BRIDGE

Abstract

This study presents the wood anatomy analysis of the historic Daran Bridge, a traditional wooden cantilever structure located over the Daran river (Sar & imath;veliler, T & uuml;rkiye), that has been in use since the 19th century. Two structural timber samples were examined microscopically using transverse, tangential, and radial sections. Anatomical features such as distinct growth rings, absence of normal resin canals, dentate torus in bordered pits of the tracheid walls, and cross-field pits with a piceoid to taxodioid shape led to the taxonomic identification of Cedruslibani L. (Taurus cedar). The species is native to Southern Anatolia, and the bridge is located within its natural distribution area. Physical and mechanical property analysis (e.g., density: 530 kg/m3; bending strength: 70-85 N/mm2) confirmed the wood's high durability, strength, and suitability as a load-bearing element. Historically, the selection of Taurus cedar was based on its local availability and resistance to environmental degradation.
