Pull-Out Performance of Densified Wood Dowels Embedded into Glued Laminated Timber
Publication: Journal of Materials in Civil Engineering
Volume 35, Issue 9
Abstract
Due to the corrosion of fasteners by water-based preservatives, the preserved timber in outdoor environments can decrease the service life of the metal fasteners. In addition, the segregation of timber members and metal fasteners is also difficult during the demolition of timber structures. Wooden fasteners can be a promising alternative to metal fasteners because they have favorable resistance against corrosion and are more naturally harmonized with timber members. This paper studied the pull-out performance of dried densified wood (DW) dowels embedded into glued laminated timber (glulam) parallel to the grain with three different embedded lengths in two ambient environments with a temperature of 20°C and relative humidity (RH) of 65% and with a temperature of 20°C and relative humidity of 85%. The hygroscopic swelling of the dried DW dowels with a long embedded length can provide the favorable friction locking to transfer the axial load.
