Abstract
Maximum displacement demands can be obtained through non-linear time history analysis, however, many approximate methods have been proposed in recent codes to reduce the required computational time distinctive of non-linear approaches. Some of these methods are based on equivalent linearization of the system by using an effective lateral stiffness (kef) and equivalent damping ratio (¿eq). The dynamic characteristics of earthquake ground motions, ductility capacities, type of hysteretic relation...
