Analysis of Shear-Dominated RC Columns Using the Nonlinear Truss Analogy
Abstract eng: This study uses the nonlinear truss analogy for the simulation of shear failures in reinforced concrete (RC) columns. A previously established method, aimed to the analysis of RC walls, is enhanced to allow simulations of column members. The concrete constitutive equations are modified to account for the contribution of the aggregate interlock to the shear resistance. Additionally, an equation is proposed to determine the inclination angle of the diagonal members in the truss models. The modeling approach is validated through nonlinear analysis of RC columns and frames subjected to quasi-static and dynamic loads. The combination of predictive capabilities and conceptual simplicity establishes truss-based models as an attractive approach for the systematic analysis of shear-dominated, RC frame construction.
