Abstract
AbstractThis paper presents the results of an experimental study on the use of carbon fiber–reinforced polymer sheets as reinforcement for the rotational behavior of bolted glulam beam-to-column connections. Monotonic loading was applied on connection specimens to identify their stiffness, ductility, and maximum moment resistance values. Material property tests were conducted and used to provide an unbiased judgment of the reinforcing efficiency considering varied specimen qualities. Different sheet wrapping patterns and layers of sheets were examined, and the results were compared with each other and results from previous studies. It was found that carbon fiber–reinforced polymer sheets could improve the moment capacity of unreinforced connections by up to 59%, which is very close to the reinforcing ratio (65%) achieved by using locally cross-laminated glulam members. A linear relationship was found between the increased perpendicular-to-grain glulam tensile strength and the increased moment resistance b...
