| Abstract: | The seismic shear provisions of EC8 for ductile reinforced concrete walls, serving as the lateral load resisting system in
multistorey building structures are re-examined. Two aspects are considered (1) single walls, or a system comprising a number
of equal-length walls, (2) a resisting system comprising walls of different lengths. It is demonstrated, in light of recent
parametric studies, that the EC8 provisions for walls in the medium- and high-ductility classes (DC-M and DC-H, respectively)
are both in need of revision. Possible revisions of requirements and a design procedure for a wall system are presented. |
