Time-Varying Wind-Resistance Global Reliability Analysis of In-Service Transmission Tower Using High-Order Moments-Based Improved Maximum Entropy Method

Round 1

Reviewer 1 Report

1. Line 98 what is the explicit form of Xi function? 

2. Line 110 Is this a typo, I do not see delta Wse in equation 2,3,4. 

3. There are over 30 equations involved in this paper, I suggest the authors compile them in a more compact way.

Reviewer 2 Report

The objective of this contribution is to develop a time-varying global reliability analysis method of the in-service transmission tower, which can effectively evaluate the time-varying global reliability of the in-service transmission tower with the tradeoff between accuracy and efficiency. For that, the high-order moments-based improved maximum entropy method (HM-IMEM) is proposed and extended to the wind-resistance global reliability assessment of the in-service transmission tower.

The paper needs to be revised as in the actual version it is difficult to read and the employed methodology has not been clearly described. Therefore, the authors must correctly address the following questions/comments.

 

1.       English must be thoroughly revised as I have found several grammar mistakes and typos.

2.       The main point is that the employed mathematical approach cannot be clearly followed. The reader is lost in the various steps, and it is not clear how to apply such methods to the examined problem, that is the reliability of the in-service transmission tower. Therefore, the description of them must be significantly improved.

3.       Lines 83-84. Please, revise the sentence “In Section 4 …”; it looks odd.

4.       Line 114: “Based on the idea of the time of combined”. What do you want to say here?

5.       Lines 122-127: Expression “transmission tower” appears 5 times.

6.       Function Si(W,t) in Eq. (7) is not described along the manuscript.

7.       Eq. (8). What is the meaning of “s.t.”?

8.       Line 161. Please define “GF-deviation” the first time it appears.

9.       Eqs. (12)-(18). From the explanation is not clear how the method is applied. How are the weights computed or estimated?

10.   Eq. (19). What is the variable “C”?

11.   Line 213. It is not clear the role of “the upper and lower integral bounds” And how they are used in the computations.

12.   Line 216. Delete “if”.

13.   Eq. (26). What is the Greek letter Phi, for obtaining beta? Same in Eq. (28)

14.   Line 366, “compare” should be “compared”.

15.   Line 287. It is said that “the PDF gradually moves to the left”. Please, give a physical interpretation of this left displacement of the pdf.

16.   The author SL Li appears in 10 refs out of 41. I think that self-referencing is too high.

Round 2

Reviewer 2 Report

Certainly, the paper has improved regarding the first version. However, English still needs further polishing, so I recommend the support of a professional. Moreover, the description of the mathematical approach needs further clarification as it is still convoluted. Maybe, providing a flow chart will be helpful for the readers
