Parametric Study of Three Types of Timber Connections with Metal Fasteners Using Eurocode 5

Abstract

This work presents the results of three types of timber connections, in double-shear, with metal dowel-type fasteners, using the simplified equations from of Eurocode 5. All the design parameters were established and compared using three different properties of strength and density of the wood that represent the connecting members. A total of eighty-one connections were obtained, allowing for the determination of the number of fasteners needed for the applied tensile load. A large number and different types of connections allow the verification of the effect of the dowel parameters together with the wood characteristics. In all of the types of timber connections studied, the number of dowels increases with the applied tensile load, with lower dowel diameter, lower wood density, and strength. The design characteristic load-carrying capacity per shear plane and fastener also decreases with the previously considered parameters.
