Durability study of glulam timber under cyclic moisture loading
Highlights The moisture cycles present in timber bridges are simulated in this study. The influence of moisture cycles on the bending strength is significant. The influence of moisture cycles on the elastic modulus is not significant. The zones of different local moisture in glulam can be discretized by patch sensors.
Abstract Glulam timber is currently an interesting solution for building environmentally friendly and mechanically strong structures. However, little is known about the impact of Wetting/Drying (W/D) climatic conditions on glulam durability. This study evaluates the effect of W/D cycles on the bending mechanical properties of glulam. The results of this experimental study show that W/D cycles have significant influence on the bending strength. On the other hand, no significant effect is found on the elastic modulus. The moisture content of specimens is also monitored and the results provide an understanding of the sorption/desorption mechanisms in wood during cycling.
