The objective of this study was to develop predictive expressions for estimating the withdrawal force capacity various size beech (Fagus orientalis) dowels from medium density fiberboard (MDF) and particleboard (PB). Furthermore, effects base material type, dowel diameter, penetration adhesive type on were investigated. Polyurethane (PU), polyvinyl acetate based D2, (PVA) adhesives utilized glu...

Research efforts have been devoted to glue-laminated bamboo (GLB) as an alternative engineered timber. However, some research has shown that GLB exhibits brittle failure at smaller displacement when compared with Glulam. To address this issue and enhance the mechanical performance, we propose use Glass Fibre Reinforced Polymer (GFRP) reinforce in moment-resisting connections. A total of 24 conn...

Introduction: Micro-computed Tomography (μ-CT) is an increasing common technique used to reveal minute details and micro-architecture of bio-materials. With the vast dataset involved, manual analysis of images is time-consuming and impractical. The aim of this study is to develop a fully automated approach to perform three-dimensional blob analysis of μ-CT data to assist further study on the di...

The use of self-tapping screws with continuous threads as a reinforcement to avoid splitting of members in connections with dowel-type fasteners was studied in two projects carried out at the Universities of Nottingham and Karlsruhe. The reinforced specimens showed a very ductile failure mode whereas the non-reinforced specimens failed in a brittle way. Although the reinforced specimens also sh...

The present study deals with the innovation and possibilities of improving design solution a frame connection for two selected types fasteners. All specimens were made glued laminated timber. Dowel-type mechanical fasteners, combination bolts dowels, full-threaded screws used connection. main goal this research was to replace typical (common dowel-type fasteners) more modern, faster, easier in ...

For many years U.S. design codes modeled the design values of a multiple-bolt joint as the design value of a single-bolt connection multiplied by the number of bolts. The provisions were based on research conducted by Trayer (1932) who observed an equal distribution of load among bolts. This was despite the fact that research conducted as early as in the late 19 century suggested an uneven load...
