Discussion of “Study of viscoelastic and friction damper configurations in the seismic mitigation of medium-rise structures”

This paper includes various interesting aspects, for example, comparison of the effectiveness of various damper systems (viscoelastic, friction and hybrid), optimal damper configuration and location, and the influence of different types of earthquake ground motions on the response reduction by dampers.The authors draw several references for readers.In the discusser's opinion, more versatile investigations on optimal damper configuration and location have been made in the scientific community of earthquake engineering, and computing algorithms based on certain theoretical backgrounds have been proposed [Austin and
