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

This paper gives a review of seismic damage indices, with particular reference to their use in
retrofit decision making. Damage indices aim to provide a means of quantifying numerically …

The role of ground motion duration on the seismic performance of building structures
remains unclear. This paper presents results on the effects of ground motion duration on the …

A methodology for the optimal design of supplemental viscous dampers for regular as well
as irregular yielding shear‐frames is presented. It addresses the problem of minimizing the …

Las grandes ciudades modernas situadas en áreas de peligrosidad sísmica moderada o
baja tienden a minusvalorar el peligro sísmico ya descuidar precauciones básicas de …

Composite moment frames consisting of steel beams and reinforced concrete columns (so
called RCS moment frames) are one of several types of hybrid systems gaining acceptance …

Nowadays, performance-based seismic design is the focus of earthquake engineering
research, in which the seismic performance of a structure is mainly evaluated based on …

Motivated by the observation that existing damage indices do not take into account the
bidirectional and torsional response effects, a new three dimensional damage index is …

Damage indices proposed in published literature quantify local and global structural
damage of buildings, subject to base excitations, on a scale ranging from zero to unity; …

The level of structural damage after an earthquake can often be expressed using the
damage ratio (DR) coefficient. This coefficient can be calculated using different formulas. A …
