New Directions in Earthquake Resisting Structures

This paper presents a new design concept for the development of efficient, dual earthquake resistingsystems. The proposed concepts lead to a novel structural configuration with provisions for selfcentering,reparability, performance control, damage reduction, collapse prevention and energy basedseismic analysis. It introduces the merits of design led analysis over the traditional methods ofapproach, followed by the development of a lateral resisting system that is more efficient than itsconventional counterparts. The new system is a combination of grade beam supported moment framesand articulated shear walls, tied to each other by means of post tensioned stabilizers and gap openinglink beams.
