Comparative study of the damage cost of reinforced concrete buildings with and without nonlinear viscous dampers subjected to seismic loading

Frontiers in Built Environment, 2022
In an optimal seismic design context, the seismic demand is characterized by hazard curves that can be obtained by simulation techniques, and the capacity of the structure is established by the designer following a predefined seismic code.
