Model Bridge Span Traversed by a Heavy Mass: Analysis and Experimental Verification
Round 1
Reviewer 1 Report
This is an interesting work.
The manuscript is sound and acceptable for publication once that the followings points are consider:
In section 2. Experimental Set up
- Please mention the value of A and I.
- Can the authors provide more details on the method at which the mass superposition and moving at the experimental setup?
- What are the possible mass and velocity ranges that can be implemented in an experiment?
- Why were the values of K1 and K2 selected as 1000kN/m and 100kN/m, and what is the contribution of these values in this paper?
In section 7. Experimental Validation
- Please include the acceleration data measured related in Figure 8 and 9.

Reviewer 2 Report
The manuscript "Model Bridge Span Traversed by a Heavy Mass: Analysis and Experimental Verification" adheres to the theme of this journal, however many corrections are needed:
a) The abstract is very generic, the innovation/contribution of this study in the literature must be presented, as well as clear quantitative results;
b) In general, the document is very similar to a technical report, which differs from a scientific article. Note that there are only 13 references, and some are not even scientific articles, this should be greatly improved;
c) Discussions are very limited and comparisons with other studies in the literature are lacking, the authors should dedicate themselves to this activity!!!

Reviewer 3 Report
This paper reports the dynamic response of a model bridge under a heavy load with a constant velocity. The quality of this paper is good. Please see the comments below.
- the mathematical derivation of this paper takes too much. To make this more concise, the author should focus on the essential parts. So please revise it.
- There are many journal papers need be cited in this paper. For example:
