Time Domain Damage Identification Approach of the Newly Hollow Floor Structure with TRMD

Round 1

Reviewer 1 Report

This paper studies the time-domain damage identification f a hollow-floor structure with TRMD. The topic is relevant to the journal. The idea is new. The paper is well organized and written. Only some minor issues are suggested before its publication.

1. It is suggested to include some discussions on the improvements of the present method compared to existing time-domain identification methods.
2. Appropriated references are suggested for the theoretical formulation in Section 2.
3. It is suggested to include some lasted literature on vibration control using passive dampers, e.g., Tuned mass damper for self-excited vibration control: Optimization involving nonlinear aeroelastic effect

Reviewer 2 Report

Dear Authors,

Remarks:

1. Literature review can be extended
2. All variables in the text and equations should be italic
3. equation 1,2, ρ is not defined
4. Minor mistakes in text should be corrected (spaces)
5. I propose to enlarge figures with results

Kind Regards,

Reviewer 3 Report

The right hand side of Equation (7) needs a negative sign.

I think the proposed TRMD system is very interesting, but if the building is damaged, the natural period will change and the effectiveness of the system will be reduced. It would be good to clarify a little more the relationship between the latter half of the study on damage identification methods and the TRMD system.
