DOI: 10.1016/j.jcsr.2021.106857
Abstract: Abstract This paper presents a simplified design procedure (SDP) for performance-based design of low-rise new steel MRF buildings with nonlinear viscous dampers. The SDP uses an effective stiffness and equivalent damping for a multi degree-of-freedom… read more here.
