In this study, high-temperature compression tests were conducted on a dowelled connection in structural glulam timbers to investigate the effect of temperature and moisture on the embedding strength and the embedding stiffness. The embedding strength and stiffness of the specimens heated below 200°C decreased significantly up to 1 hour from the beginning of heating and then the strength recovered at 4 hours with the change in moisture content. The relationship between the internal temperature and the reduction factor of the embedding strength on the parallel to the grain approximately agreed with that of the compressive strength by Eurocode 5.
