The objective of this study is to investigate the effects of carbon fiber reinforced plastics (CFRP) on glued laminated timber bridges. Simple beam bridges made of glued laminated timber have comparatively short span length, however, the span length can be expected to be longer if it is reinforced by CFRP. Different eight glulam beams were made for loading tests. Two kinds of CFRP are used in this study. One is a sheet type, and the other is a plate type. The epoxy resin was used between wood and CFRP. As a result of tests, failure loads of reinforced beams were about 1.5 times the beam without CFRP. The main failure mode was the combination of sheet exfoliation and tensile crack of wood. The CFRP reinforcement can improve the load carrying capacity of glulam beams effectively.
