20.500.12556/DiRROS-17386 Experimental investigation of the axial strength of glued-in rods in cross laminated timber This paper presents results from an experimental assessment of glued-in rods in cross laminated timber (CLT). For the purposes of the study more than 60 pull-pull tests were performed, where the specimens varied in terms of bonded-in length (from 80 to 400 mm), rod diameter (16-24 mm) and rod-to-grain angle (parallel and perpendicular). Several different failure modes that are not common for other applications of glued-in rods (e.g., a failure between CLT layers) were obtained for the analysed CLT specimens. It was found that these failure mechanisms can substantially influence the obtained ultimate tension loads. At the end, the experimental results were compared with empirical and semi-empirical equations for estimating the pull-out strength of glued-in rods in structural timber and glulam. The comparison showed that most of the existing equations overestimate the ultimate tension loads for specimens with the rod parallel to the grain and underestimate the ultimate tension load for specimens with the rod perpendicular to the grain. The results vary because the possible CLT failure modes were not included in previous studies. Further studies are proposed to improve the equations for glued-in rods in CLT. glued-in rods cross laminated timber (CLT) pull-pull experiment glued-in length rod-to-grain angle failure mechanisms in CLT lepljene palice križno lepljen les (CLT) natezni preiskus sidrna dolžina palice usmerjenost palice glede na vlakna porušni mehanizmi v CLT true false true E. & F.
