Shear-Flexure Interaction for Structural Walls

This paper proposes an analytical model that couples the flexural and shear responses of reinforced concrete (RC) structural walls. The proposed modeling approach involves incorporating RC panel behavior into a macroscopic fiber-based model. Results obtained with the analytical model are compared with test results for a slender wall and four short wall specimens. A reasonably good lateral load-displacement response prediction is obtained for the slender wall. The model underestimates the inelastic shear deformations experienced by the wall; however, shear yielding and coupled nonlinear shear-flexure behavior are successfully represented in the analysis results. The model captures accurately the measured responses of selected short walls with relatively large shear span ratios (e.g., 1.0 and 0.69). Discrepancies are observed between the analytical and experimental results as wall shear span ratios decrease (e.g., 0.56 and 0.35). Better response predictions can be obtained for walls with low shear span ratios upon improving the model assumptions related to the distribution of stresses and strains in a wall.
