dc.description.abstractMonitoring and evaluation of glued laminated timber structures in service is essential to warrant its integ rity, where non-destructive techniques play an important role. This paper describes the results obtained on glued laminated timber beams of maritime pine, with and without preservative treatment, and of spruce, exposed to natural outdoor environment as well as to artificial weathering. The assessment of glue lines’ shear strength was investigated through the extraction and testing of cores parallel and per pendicular to the glued lines and block shear specimens with 50 mm×50 mm and 20 mm×20 mm shear area. The results highlight the different performances of the various types of specimens tested, showing that the measured shear strength depends on the specimen size and that the size effect depends on the material strength giving a decreasing modification factor with the increase of strength in opposi tion to the constant factor suggested by standard EN 14080. They also show that shear testing of cores drilled perpen dicular to the glued joints may be a promising tool in the assessment of glulam structures on site.pt_PT
