Abstract
Nonlinear numerical analysis was performed to evaluate the moment–curvature relationship and deformability of flexure-dominated walls
with partially confined end-zones. Through the numerical analysis, the effects of design parameters on the behavioral characteristics and the
failure mechanism of the walls were studied. The results showed that the lateral confinement in the end-zones of the cross-section increased the
deformability of the wall by reducing the depth of the compressive zone as well as by increasing the deformability of the confined concrete. The
deformability of the wall significantly increased as the compressive strength of the confined end-zones approaches the applied axial force. Based
on the results, design equations for predicting the moment–curvature relationships and the deformability of the walls were developed.
