Reviewer 2 Report

The author has mentioned very good research in the manuscript and has tried to explain each and every step very coherently but I feel that if the minor shortcomings of the paper are addressed then the paper will become more coherent.

1.      The author's choice of research title " Analysis of Fire Resistance of Prestressed Concrete T-beam Based on ABAQUS Numerical Simulation " has already seen a lot of influential work, so what inspired the author to do this research?

2.   Need an application of a theoretical or methodological perspective that sheds light on the issues addressed in the focal article.

3.    Add few sentences about the importance/significance of the present work

4.  The conclusion needs to be reorganized. There is no need for such a simple summary of the test results. The test results need to be condensed to obtain useful conclusions.

5.  The research work referred by the author for this research work is very less, so the author should add some recent research work, in addition to adding some old research work related to his study.

6. In general, the readability of the paper needs to be further strengthened. The author is only a brief description of the test results. The thesis should pay more attention to the disclosure of the causes of experimental phenomena, so that it can have real reference significance. The work carried out by the author in the elaboration of the significance of his research, the design of the research plan, and the description and interpretation of the test results are all insufficient.

Reviewer 3 Report

This study studied the effects of different fire modes, different concrete strength classes, different flange thickness, different prestressing bar reinforcement rates and different concrete protective layer thicknesses were studied in three cases with constant load rates of n=0.4, n=0.6 and n=0.8. It was interesting for the fire resistance design of prestressed concrete T-beam in engineering practices. However, many issues still needed to improve before it was accepted. They were:

1.      The literature should be updated, more literature should be in recent three years.

2.      The introduction should be improved with more technical details and more reference materials.

3.      Several mistakes or not clear sentences are present in the manuscript. An extensive English editing is mandatory.

4.      It lacks necessary physical model test or literature verification.

Reviewer 2 Report

The answer given by the author is not satisfactory, the author should make a deep observation of his research work from old research works, which will be easy to answer and there will be no problem in future research works.

Author Response

The authors wish to thank the reviewer for your time in effort in reviewing our manuscript. Firstly, the authors apologise for the unsatisfactory response given. The authors have made changes in response to the reviewers' suggestions. New relevant studies have been added to the introduction and the description of the research work has been improved.

Reviewer 3 Report

The physical model test is still lacking，and it should be increased, which shows the applicability of the calculation model.

Author Response

Thanks for the reviewer’s suggestion. The authors also consider the validation of physical models to be essential. However, the current test setups for fire resistance studies are complex and expensive, and are somewhat hazardous. Therefore, finite element simulations are usually used to investigate fire resistance. It has also been shown that finite element models can perform fire resistance simulations with a high degree of accuracy. In this paper, the analysis of the relevant parameters is carried out to obtain fire resistance data from a validated finite element model. The final computational model is also validated.

Authors appreciate the reviewer’s constructive suggestion again and we sincerely look forward to your understanding.
