Optimal design of passive viscous damping systems for buildings under seismic excitation

Nowadays, it is known that through the use of energy dissipation devices, the seismic performance of buildings can be improved. However, for efficiency and structural safety, the locations and sizes of these devices need to be properly defined. In this work, a procedure to optimally define the dampi...
