Development of Vibration Control Structure on Suspended Ceiling Using Pulley Mechanism
Round 1
Reviewer 1 Report
this study developed the innovative passive vibration control device for an indirect suspended ceiling system by using PDCS and the large scale suspended ceiling system was conducted on a shaking table. Also, the results of numerical simulation model was validated by the experimental test. Therefore, this paper will be appropriate to publish the journal of Applied Science with the novelty of the results to mitigate the earthquake nonstructural earthquake damage. However, the minor recommendation is as follow:
- need to check references, for example, the number of 9 reference is not on the journal of structural engineering, but it is on the journal of earthquake engineering.
- check spell of the paper.
- need to explain more or details about STERA 3D software
- need to mention the error or difference in terms of the reasons that cause the gap between the experimental and analytical model or results.

Reviewer 2 Report
The authors developed an indirect suspended ceiling system (SCS), named pulley damper ceiling system. A series of shake table tests were conducted to verify the efficiency of the dampers. An analytical model was also developed. The paper is well written and informative. Therefore, it is recommended for publications. There are some minor comments as follows:
- There are some typos, e.g., Fig. 2 primaly structure, Fig. 11 steel test fram
- 4b: the definition of alpha should be further explained, what are K1 and K2?
- Table 5: the unit of damping coefficient is missing
- Figure 23: why did not provide the velocity time history curves?
- The conclusions should provide some quantified results.
