T-shaped walls of different web-flange ratio with varying axial load, reinforcement content and distribution within a representative range of values are analysed in order to determine the curvature trends for three limit states, i.e. serviceability, yield and ultimate. A comprehensive set of equations for yield, serviceability and ultimate curvature is proposed, indicating the level of uncertainty for each expression. The proposed expressions, being adapted to different levels of precision and accompanied by graphical representation, lead to the reliable computation of limit-state curvatures, essential within a displacement-based design approach, and can be utilised in the realistic estimation of appropriate ductility factors in the design of T-shaped walls. Furthermore, the results regarding the section properties of T-shaped walls, such as the elastic stiffness and the moment capacity for opposite directions of loading, offer additional information useful in the design of T-shaped walls.
