pThis study presents detailed information on the calibration of a nonlinear wall macromodel by comparing model results with experimental results for slender reinforced concrete walls with rectangular and T-shaped cross sections. Test measurements were processed to allow for a direct comparison of the predicted and measured flexural responses. Responses were compared at various locations on the walls. Results obtained with the analytical model for rectangular walls compare favorably with experimental responses for flexural capacity, stiffness, and deformability, although some significant variation is noted for local compression strains. For Tshaped walls, the agreement between model and experimental results is reasonably good, although the model is unable to capture the variation of the longitudinal strains along the flange.
