The Seismic Behavior of Rectangular Concrete-Encased Steel Bridge Piers: A Review

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

This is a review article concerning the seismic behavior and simulation of concrete-encased steel bridge piers. The paper was well written but some commnets should be answered as follows:

1- These figures from literature are not sufficiently clear enough for readers and should be edited and revised:

Figure 2, what are the unit of the dimensions?

figure 5 What are the values on the curves? they should be presented in the text before the figure.

Figure 10 The figure is not clear enough and a description should be added to the text about this figure and its details.

2- It is recommended to make a flowchart and introduce the process of deriving the confinment factors which facilitate the process for readers.

3-A table should be added to section 5 and all the literature studies concerning the seismic behavior of the concrete-encased steel bridge piers should be presented. The whole text will be summarized in the table. type of the analysis, year of the study, name of the authors, achievement of the analysis etc.

4- The title of section 5 should be revised. The title of the section is the same as the title of the paper which does not make sense. This should be revised to be more specific becasue it is a section of the paper and more specific data will be presented in the section.

5- This is a review study, therefore the authors should be sure enough that all the relevant studies were reviewed and presneted in the paper. Some references are missing:

Reviewer 2 Report

Comments and Suggestions for Authors

-being a review article, it is good to present the disadvantages of concrete-encased steel bridge piers (for ex.: construction complexity, quality control, initial costs, repair and inspection difficulties, enviromental impact, thermal expansion issues.... )
- in the first section CES column configuration, circular sections must be introduced;
- the minimum and maximum dimensions of the section must also be highlighted (fig.3);
- the total area of the CES bridge piers reinforcement (round bars and metal profile) will not exceed .....% of the area of the concrete section;
- it is not specified which ratios are accepted between the buckling lengths of the columns and their width, h/d;
- the minimum characteristic strength for concrete and steel are not specified (see ACI, CAN/CSA or EC4 standards);

- can you estimate and predict the torsional behaviour of CES bridge piers, which are the key factors (at point six, page 15)?
