Bending moment capacity of metal plate connected wood-splice joints constructed with red pine (Pinus brutia ten.) lumber

Öz:

Özet: Bu çalışmada Kızılcam {Pinus brutia Ten.) kerestesi kullanılarak yapılmış metal plakalı uç birleştirmelerinin moment taşıma kapasiteleri araştırılmıştır. Birleştirmelerin yapılmasında 38 mm x 90 mm enine kesitinde kereste ve üç farklı metal dişli plaka kullanılmıştır. Birleştirmelerin maksimum moment taşıma kapasitlerinin bulunmasında dört-nokta yükleme metodu tatbik edilmiştir. Metal plakalı uç birleştirmelerine yatık ve dik pozisyonlarda eğilme testleri uygulanmıştır. Diş yönünün ve metal plaka boyutunun birleştirmelerin moment taşıma kapasiteleri üzerine etkisi de çalışmada araştırılmıştır. Elde edilen bulgular hem diş yönünün hemde plaka boyutunun birleştirme kapasitesi üzerinde anlamlı etkisi olduğunu ortaya koymuştur. Plaka boyutu 76 x 76 mm'den 76 x 100" mm'ye çıktığında birleştirme moment kapasitesini yükseldiği görülürken, 76 x 100 mm ile 76 mm x 152 mm plakalar ile yapılmış birleştirmeler arasında istatistiksel olarak anlamlı bir fark görülmemiştir. Ayrıca birleştirmelerin yapımında kullanılan kerestenin özgül ağırlığı, elastikiyet modülü ile moment taşıma kapasiteleri arasında anlamlı bir ilişki bulunamamıştır.

The ultimate bending moment carrying capacity of metal-plate-connected (MPC) wood-truss-splicejoints constructed with red pine {Pinus brutia Ten.) lumber was investigated. Lumber 38 mm by 90 mm and 3 different sizes of metal plate connectors were utilized in constructing the joints. A 4-point loading method was used to determine thejoints' bending moment capacity. Tensile splice joints were tested in both flat- and edgewise positions. The effects of tooth orientation and metal plate size on the bending moment capacity of the joints were investigated. The results indicated that both tooth orientation and plate size significantly influenced thejoints' bending moment capacity. Plate size seemed to increase the bending moment capacity of thejoints when plate size was increased to 76 mm by 100 mm from 76 mm by 76 mm. There was no significant difference between 76 mm by 100 mm plates and 76 mm by 152 mm plates in bending moment capacity. There was also no conclusive relationship between the bending moment capacity of thejoints and the specific gravity of the lumber, and between the lumber's modulus elasticity.
