Abstract

The present work focuses on analysis of deformation and strength behaviour of slotted-in steel plateconnections in glued laminated timber (GLT). In Eurocode 5 (EC5), the design of metal dowel-type timber joints is basedon the yield theory presented by Johansen [1]. It consists of analytical expressions to calculate the lateral load-carryingcapacity of single fastener joints that exhibit different (plastic) failure modes. When designing optimised multiple fastenerconnections that are exposed to dominating moment action, the calculation of fastener forces and their directions duringprogressive plasticization of the dowel group is difficult to perform manually. Therefore, a simple numerical model tosimulate progressive elasto-plastic force development for every individual dowel is needed. This study presents new andsimple models to analyse the bending deformations of glulam beams jointed with mechanical slotted-in steel plateconnections. The proposed models were experimentally verified using results obtained from a joint project with theMaterial Testing Institute (MPA) at University of Stuttgart.
