TLDR
In this paper, a stepwise seismic design procedure is proposed of tapered integrated wall-footing systems with soil or rock anchors at the bottom of the wall, which incorporates a capacity design of the plastic hinge region above the tapered portion and an elastic design of a tapered part.Abstract:
In a companion paper, new tapered configurations are proposed of slender RC structural walls with and without enlarged boundary elements at the wall-footing junction region. On the basis of identified parametric limits and the wall response in linear-elastic finite-element analyses, a stepwise seismic design procedure is proposed of tapered integrated wall-footing systems with soil or rock anchors at the bottom. This incorporates a capacity design of the plastic hinge region above the tapered portion and an elastic design of the tapered portion. The location of the region of seismic damage and energy dissipation in the wall is controlled by proportioning of the tapered wall-footing as per the new design procedure.read more

Aspects of drift and ductility capacity of rectangular cantilever structural walls
TL;DR: In this paper, moment-curvature analyses of cantilever shear walls are used to determine available displacement ductility factors for walls of different aspect ratios and drift limits.

Stability of Ductile Structural Walls
Thomas Paulay,M. J. N. Priestley +1 more
TL;DR: In this paper, the authors proposed that the major sources of instability of the compression zone of the wall section within the plastic hinge region are inelastic tensile steel strains imposed by preceding earthquake-induced displacements, rather than excessive compression strains.
