A METHOD TO IMPROVE THE SEISMIC BEHAVIOUR OF ECCENTRICALLY BRACED FRAMES

H Köber, M Stoian

The present paper is intended to enhance the inelastic response under severe seismic actions of some eccentrically bracing systems equipped with additional vertical connection elements (vertical truss elements between the ends of all dissipative members that are not connected directly to columns) compared to the seismic behaviour of traditional eccentric bracings. Each considered structural type (with and without additional vertical truss elements) is subjected to three dynamic nonlinear
