Existing approaches used to model the lateral force versus deformation responses of walls, typically assume uncoupled axial/flexural and shear responses. A more comprehensive modeling approach, which incorporates flexure-shear interaction, is implemented, validated, and improved upon using test results. The experimental program consisted of reversed cyclic lateral load testing of three-quarter scale, heavily-instrumented, wall segments dominated by shear behavior. Model results indicate that variation in the assumed transverse normal stress or strain distribution produces important response variations. Use of the average experimentally recorded transverse normal strain data, or a calibrated analytical expression for the horizontal strain, resulted in better predictions of shear strength and lateral load-displacement behavior, as did incorporating a rotational spring at wall ends to model extension of longitudinal rebar within the pedestals.
