This commit proposes a refined formulation of the SFI_MVLEM element aimed at improving the consistency and tractability of the numerical solution procedure. The enhanced model introduces explicit implementation of the interaction between axial and shear stress-strain relationships. Furthermore, the refinement accounts for axial-shear interaction effects via an extended constitutive matrix that preserves coupling between normal and shear responses. The resulting formulation improves the consistency of tangent stiffness computation, particularly for nonlinear material models, and ensures better equilibrium with residual forces during iterative analysis. The proposed refinements advance the modelling fidelity and computational robustness of the SFI_MVLEM element, making it more suitable for complex nonlinear dynamic simulations of RC shear wall structures.
