Behaviour of Heavy Timber Members Subjected to Sequential Shocktube-Simulated Blast Loads
This paper presents the results of an experimental programme investigating the effects of repeated dynamic blast loading on the behaviour of glued-laminated timber (glulam) beams and cross-laminated timber (CLT) panels. The specimens were subjected to a total of eight dynamic four-point bending tests using the University of Ottawa Shock Tube Test Facility. Control specimens were subjected to a single blast load causing failure, in order to document the load–displacement behaviour without the risk of inducing damage accumulation. Other specimens were then subjected to multiple blast loads, to investigate the effect of repetitive loading on the bending stiffness and capacity, as well as damage accumulation. Post-peak behaviour was found to vary significantly between glulam and CLT specimens, which greatly affected how the specimens performed when subjected to multiple blast loads. The outcome of this study is expected to contribute to knowledge base for heavy timber members subjected to blast loads in situations where exposure to multiple shock waves is probable, such as shock wave reflection emanating from nearby buildings, or during research testing where the timber element is considered for multiple tests.
