Reviewer 1 Report

The paper is interesting, however Figures 5 and 8 do not contribute much to the article.

Reviewer 2 Report

The main contribution of this work is the demonstration of a simplified calculation model for the determination of the frequencies of normal modes of Hidden frame glass curtain walls. The manuscript is well written, and the conclusions are supported by the results. In my opinion, the work would be greatly enriched with a theoretical background section, maybe provided as supplementary material. I recommend this manuscript for publication after the following points are addressed by the authors:

• Line 68 – Check typo: “he two full-sized…”
• The authors do not report experimental errors for any of the values reported in the manuscript. Please, provide experimental errors for all experimental and calculated values.
• Line 130 – please, provide references for Equations 1 and 2.
• Please, specify the individual values of m and n (as from Eq. 1) for the reported modes. In this sense it will be easier for the reader to understand the equivalence of modes 2,3 and 5,6 for models 1 and 2 of sample A.
• Line 184 – please, provide references for Eq. 4 and 5.
• Figure 9 – Please, include the relative errors for Model 3 (the best model from the previous approach), for the sake of comparison.
• Line 216 – Check typo: “… the modal 6 can be used as as the simplified …”
• Lines 216-220: How the simplification in the model affects the computational processing times? Please, discuss this in the manuscript, if relevant.

Reviewer 3 Report

The article presents the results of experimental and numerical analysis of natural oscillations of Hidden frame glass curtain wall. The methodology for conducting the experiment is presented. The results of comparison of various finite element models with the experimental one are also presented. The article may be of some interest in the design of these structures. The article contains some inaccuracies.

1. When writing an article, the list of references should be expanded.
2. Usually, at the beginning of the article, the authors consider various models and describe methods and test complexes, and then measure and compare the results. The article describes the materials quite the opposite. The authors apparently need to restructure the article.
3. There is an error on line 65 - ”panel uints”
4. In chapter 2.2, the authors describe the data collection methodology. It is not clear what actions the authors performed during signal processing. Has the received signal been normalized? Typically, accelerometer sensors collect data on accelerations at a point in a structure. And the authors below cited their own forms of vibrations. How did they calculate the displacements?
5. It is not clear what some of the parameters described in lines 131-133 are equal to, for example ℎ? the height of the plate
6. It is not clear in what complex the calculations were made. If the authors considered their own FE solution, then it is necessary to give its justification.
7. In Figure 4, the authors show the first 6 vibration modes of the model. It is not clear what place they occupy in research?
8. In chapter 2.3, authors should give a numerical description of the frequency difference between the two models.
9. In Figure 5, the authors need to specify the differences between the models in more detail. It is necessary, using the example of Figure 7, to show the difference between all the presented models.
10. It is not clear what the parameters , ?? and ?? , described in lines 185-186, are equal to.
11. In lines 128-130, the authors must provide a link to the given analytical solution.
12. In Figure 5, the authors need to specify boundary restraints.
13. Is it possible to compare numerical models with an analytical solution using formula 1?
