Fluid viscous dampers (FVDs) are well-established supplemental energy dissipation
devices that have been widely used for earthquake protection of structures. Optimal design …

Structural weakening and addition of damping is an approach previously proposed for the
reduction of seismic forces and drifts in the retrofit of structures. It is also used in the design …

This paper presents a practical multi-level performance-based optimisation method of
nonlinear viscous dampers (NVDs) for seismic retrofit of existing substandard steel frames. A …

Continuing the tradition of the best-selling Handbook of Structural Engineering, this second
edition is a comprehensive reference to the broad spectrum of structural engineering …

The earthquake protection of structures equipped with energy dissipation devices in the form
of nonlinear fluid viscous dampers (FVDs) is investigated. Most of the optimal design …

Installation of damping devices has been limited to diagonal or chevron brace configurations
until the recent development of the toggle-brace configurations. These configurations …

This state of the art report from an international task group (TG44) of CIB, the International
Council of Building Research Organizations, presents a highly authoritative guide to the …

The effect of damping on the response of elastic and inelastic single-degree-of-freedom
systems was studied by nonlinear response-history analysis using earthquake histories that …

The concept of apparent weakening by adding true negative stiffness to a structure has been
previously introduced by the authors in order to reduce simultaneous drifts, accelerations …
