On Contraction of Three-Dimensional Multiple Shear Mechanism Model for Evaluation of Large Scale Liquefaction Using High Performance Computing
Round 1
Reviewer 1 Report
1. p. 3, l. 11: normal unit vector => unit normal vector
2. p. 3, l. 14: Please show e1 and e2 in Fig. 1 or Fig. 2.
3. Eq. (8): Please show integration range.
4. I could not understand why enormous amount of memory is required to conduct integration in Eq. (8).
5. l. 5 of Section 2.2: Plane \Pi is not defined (Only written in Fig. 3)
6. p. 6 2nd line from the bottom: I could not understand “The loading condition was repeated with 30kpa”.
7. p. 7, l. 5: Why is the amount of memory reduced by the symmetrical installation of springs?
8. p. 7, 4th line from the bottom: The numbers of springs 288 and 144 should be indicated in Fig. 6. I could not understand which plots give the same degree of relative error.
9. Table 1: Niahiya/ma => Nishiyama
10. p. 11, l. 2: The reason why the viscous BC was not set on the sides of the ground model should be described.
11. p. 11, l. 8: dumping => damping
12. p. 11, l. 8: Are these damping factors also used in the soil region? I think that the damping factors for soil and those for the structure are very different.
13. Fig. 13: Please modify the color bar. It is difficult to compare Figs (a) and (b).
14. p. 13, l. 1: What is “representative calculation steps”?
15. Fig. 15: What is “values obtained by normalizing calculation memory”?
16. Section 3.3: How many (computation) nodes were used?

Reviewer 2 Report
The authors studied the usability of the developed FEM for the evaluation of liquefaction. The reviewer feel that the developed numerical is useful for large scale computing.
1) Chapter 2
The chapter 2 is almost the same as another under-review manuscript which was submitted to the Journal of Japanese Society of Civil Engineers.
https://www.jstage.jst.go.jp/browse/jscejam/-char/ja/
The authors of another manuscript are the same as this manuscript. The authors should cite the original one.
2) Chapter 3
There is no descriptions of the material parameters of structures.
3) Figure 10 and Table 1, 2
The types of layers do not match in Figure 10 and Table 1, 2. Use consistent name of the layers.

Reviewer 3 Report
The authors proposed a non-linear constitutive relation based on multiple shear mechanism to reduce the computational demand of seismic analysis aimed to assess soil liquefaction.
The proposed model has been verified by using a benchmark of NPP and well-established soil model.
The proposed model pretty well simulates the cyclic mobility by reducing the required CPU memory.
The paper is well-structured and well-written. Interesting results have been obtained.
I believe the paper is worth of publication as it is but you may consider to change the title tin order to highlight your proposed model
