Abstract

Yield penetration or slip deformation is characterised by a rigid body rotation of the column associated with a gap opening at the column-foundation interface from the penetration of inelastic strain in the tensile reinforcement embedded in the foundation. The rigid-body end rotation increases the total drift significantly and has to be separated from flexural deformation obtained from curvature distribution over the column height. The yield penetration deformation model is developed based on a displacement-controlled principle using a new approach where the local steel strain as a function of the column global displacement is presented. In order to solve the strain incompatibility between s..
