Round 1

Reviewer 1 Report

Exploring the mechanism of damaging CLT Panels as a result of exceptional actions (explosion, implosion in construction objects) better and better, it should be also considered how they will affect the adjacent structures of other building partitions connected to them, transferring not only their own weight, but also other loads acting in different directions. Since CLT panels, which can be the load-bearing structures of buildings and structures, will be loaded both - horizontally and vertically, therefore, in the future, such loads should be taken into account in subsequent tests and their load-bearing capacity should be assessed after the dynamic loads have subsided. The tests carried out and described in the article concern only the exceptional load of panels perpendicular to their surface. Such advanced research could also alternatively analyze the possibility of using composites in order to strengthen and protect CLT panels against their complete damage, allowing to avoid or delay the occurrence of a possible disaster in building structures.

Reviewer 2 Report

Dear Authors,

The overall merit of your paper is very high.

Introduction is well written and provides sufficient background to the topic under consideration.

Experimental stand is clearly described "step by step" and well designed. I really appreciate the 3D models with detailed specification in the figures.

The detailed description of the force-time history of the tested samples and corresponding damage progression make the results interpretation to be clear for the reader.

The one thing that could be added to the paper is more bitmaps from DIC method, comprising damage progression. I know that when the sample is damaged, the stochastic pattern in this place is also damaged, but results from other places e.g. clamping area during an each phase of the experiment may be also interesting. It is only my suggestion to prepare this kind of bitmaps (as in Figure 30) corresponding to Figures 23, 24 and 27, 28. This remark does not influence the very high overall impression of the paper.

Best regards, Reviewer
