Seismic Resilience and Design Factors of Inline Seismic Friction Dampers (ISFDs)

Round 1

Reviewer 1 Report

 

1.         Please provide a notation section, and explain each symbol on the first appearance.

 

2.         You should add a detailed description of the Inline Seismic Friction Dampers, and what is the numerical equations, which describe the dynamic behavior of this system. Also, what are the other systems.

 

3.         You are talking about dissipation energy in page 1 including shear (line 37), but shear is a brittle mechanism and most code eliminate shear failure by the over-strength concept. You must modify and comment.

 

4.         The paper does not contain any details of the analytical frame analysis of the linear and nonlinear schemes including materials, geometric and the meshing for the frames and the added braces.

 

5.         The definitions of each variable used to calculate the response modification factor should be provided.

 

6.        Previous studies are not discussed in some details.

 

 

7.         Details of the dynamic model are not given. Also, the dynamic items such as time step, mass, damping are not given.

 

8.         Where are the material properties?

 

 

9.         Add tables to explain your results.

 

 

10.     In general, discussion and conclusions are not enough and should be explained deeply.

Reviewer 2 Report

This manuscript studied the overstrength, ductility, and response modification factors of concrete frame buildings with inline friction dampers in the Canadian context. It studied a set of four-, eight-, and fourteen-storey ductile concrete frames with inline seismic friction dampers. The seismic performance of the buildings equipped with inline seismic friction dampers was assessed through dynamic responses with twenty-five ground motion records. The functions of diagonal braces and span length (6m and 8m) were investigated. Generally, this article is readable and clearly expresses its focus: energy accumulation and dissipation. I just have following minor comments:

 

1.     Figures: Figures are too small to read with difficulty. The resolution quality is also expected to be higher. It is better to use the vector figures with high-resolution for clear printing.

2.     Terminology: Some terminologies should be clearly defined before use such as overstrength, pushover, response modification factors.

3.     English and presentations: Some improvements on presentation are still necessary. ’10-stories’ is ’10-storeys’? same for ‘story’ à ‘storey’? 1.0D+1.0E+0.5L+0.25S needs some explanations!

Terminologies should be explained before use and some words are not the same meanings as mentioned.

Round 2

Reviewer 1 Report

The quality f the paper is enhanced and more details are added.

I have some comments:

- Some grammar and language mistakes still exist.

- Add equations for the bracing member.

- Also, explain the change f the drift and inter-story drift.

- Explain the effect of height and span length and give comments.

- Add a separate section for conclusions.

- Update references.

 

Some minor language errors and mistakes.
