Performance of CLT panels under blast loading

对木材进行的爆炸试验非常有限，部分原因是木材由于其质量低和易碎的性质，不被视为抵抗爆炸载荷的可行选择。NORDIC新型X-Lam交叉层压木材的推出为在防爆结构中使用木材开辟了巨大的可能性。研究将集中在CLT板的抗弯承载力以及板的边界处的连接，以建立延性比的设计要求。当受到爆炸载荷时，将使用真实的边界条件研究CLT板不同损伤水平的响应极限。还将调查高应变率对CLT抗弯承载力的影响，并确定动态增加因子（DIF）。

Blast testing on wood has been very limited, partly because wood, due to its low mass and brittle nature, is not seen as a viable option to resist blast loads. The introduction of NORDIC's new X-Lam cross-laminated timber opens up great possibilities for using wood in blast resisting structures. The research will focus on the flexural capacity of the CLT slabs as well as the connections at the boundary of the panels, to establish design requirements for ductility ratios. Response limits for different damage levels of the CLT panels will be investigated with realistic boundary conditions when subjected to blast loading. An investigation of the effect of high strain rates on the flexural capacity of CLT and determine a dynamic increase factor (DIF) will also be undertaken.
