Abstract
This paper presents an experimental program that examined the behaviour of seventeen full-scale reinforced cross-laminated timber (CLT) slabs subjected to simulated blast loading using a shock tube. The CLT slabs were retrofitted with steel straps and glass fibre-reinforced polymers (GFRP).The results from the experimental program show that reinforcing the panels with steel straps had minimal effect on the ultimate strength, but significantly affected the post-peak resistance and ductility. The horizontal straps were able to restrict the failure to small regions and promote flexural failure by preventing rolling shear failure. Applying GFRP enhanced the overall behaviour of the slabs, resulting in a significant increase in peak resistance, ductility, stiffness as well as the post-peak resistance.
