Short Term Lateral Shear Loading of Nailed Spruce-Steel-Spruce Flitch Joints and the Modification of Eurocode 5 Predictions for Design Resistance

Abstract

Parvez Alam and Martin P Ansell

In this paper, spruce-steel-spruce flitch joints connected by shot fired nails are subjected to short term loads. The failure modes and design resistance equations are compared with those detailed in Eurocode 5. The formation of a plastic hinge is observed in the nails at the steel-timber interface and Mode I (tensile opening) occurs longitudinally along the grain following the row of nails. The predictive equations of force in Eurocode 5 for dowel-type joints are modified with respect to yield moment and unequal fastener penetration depths to produce a significantly improved predictive equation for force.
