Response modification factor for steel and reinforced concrete structures with viscous dampers

The response modification (R) factor serves a main function in the seismic design of building structures nowadays and is considered to be one of the seismic design parameters in the process of equivalent static analysis. In the last two decades, the application of damper systems as earthquake energy...
