The ACI 318-02 specification suggests a simple expression that is a function of story height for estimating tension flange effective width in flanged reinforced concrete (RC) shear walls. Other influential variables such as drift level, wall width, and the level of axial load are not addressed in the ACI expression. A detailed finite element model is used to investigate the effect of these parameters on the tension flange effective width. The finite element model accounts for nonlinear steel and concrete behavior and is validated through comparisons to test data. The analytical results show that the tension flange effective width is strongly dependent on all the variables investigated. implications of the presented data regarding existing guidelines are discussed and provisions, are suggested that are suitable,for implementation in performance-based design criteria.
