Forced convection fire spread along wooden dowel array

Fire Safety Journal, 2021
Abstract The effects of freestream flow on fire spread behaviors of a discrete wooden fuel array were studied. The spacing between fuel elements was varied, and the flame spread behavior under 1, 2, and 3 m/s forced flow velocities was investigated. The fastest spread rate was not observed for the smallest spacing. Furthermore, increasing spacing did

Improvement of glued-in-rod joint system using compressed wooden dowel

Holzforschung, 2010
Abstract The purpose of this study was to develop eco-friendly and high-performance glued-in-rod (GIR) joints using compressed wood (CW), which has higher tensile strength than normal hardwood, instead of conventional wooden dowels. To explore the bonding performance of the dowel and base material, punching shear tests were performed and ...

Stiffness Prediction of Wooden Dowel Connections with Beam-on-Foundation Models

Journal of Structural Engineering
The renewed interest in pure wood connections has brought wooden dowels back into focus. They exhibit satisfactory mechanical properties in terms of strength and ductility. However, while significant research has been dedicated to capacity models, stiffness models have received less attention.
