Structural Responses of a Supertall Building Subjected to a Severe Typhoon at Landfall
Round 1
Reviewer 1 Report
In this article, authors examined the dynamic response of a high-rise building under the effects of a very strong tropical typhoon. The system dynamic characteristics are extracted utilizing SHM system measurements data. Results are verified against numerical simulations.
Most of my comments are provided in the attached PDF. Two of my general suggestions are as follows:
- However, the methodologies are well defined and verification/validation is demonstrated appropriately, the contribution merit of the manuscript is not well established. Please elaborate more on this topic.
- Please be noted that more than 50% of the references are published more than a decade ago. Please consider/add more recent research works reviews, as well.

Reviewer 2 Report
The authors work on identification of modal parameters (natural frequency, damping ratio and modal shape) via two kinds of methods: stochastic subspace identification (SSI) method, and a method based on combined use of spectral analysis and random decrement technique (RDT). Firstly, they obtained in-situ measurements at two sites where a high-rise building is located. Based on the wind velocity acceleration responses of the building is then obtained and the building’s serviceability is assessed based on several comfort criteria. After that the authors applied the above-mentioned ID methods and the dynamic characteristics of the tall building were calculated and compared with simulation results via finite element method. The good agreement between the two kinds of results demonstrates the effectiveness and accuracy of adopted methods. The authors are also addressed the amplitude dependence of natural frequencies and damping ratios of the study building. Data that were obtained in the paper show promising results on both numerical and experimental cases.
The paper addresses a topic posing numerical and experimental challenges and having practical significance. It is methodologically correct. The paper is suitable for publication.
The literature review in introduction is thorough and it is very well written, however some additional reference listing below regarding the control of structural response subjected to wind loading which can be applied in tall buildings could be added in the introduction chapter.

Reviewer 3 Report
- This paper studies the structural responses of a tall building subjected to a severe typhoon, which provides a good reference for building design and performance monitoring.
- The paper is written well and easy to read, but not up to the publication standard. A professional proof reading is recommended to improve the writing and eliminate mistakes in the paper. For example, Line 247 “Canto” should be “Canton”, etc.
- In Table 1 “anemometers” should be “accelerometers”. Many places in the text should be corrected accordingly.
- Line 100, what’s the meaning of 1822?
5. The authors states that one of the advantages of this research is to have measurement data from multiple heights, but it is not demonstrated how all the data from different heights were used.
