Abstract

© 2014 John Wiley & Sons, Ltd.This paper uses nonlinear truss models for the analysis of shear-dominated reinforced concrete (RC) columns subjected to cyclic loading. 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 using the results of quasi-static and dynamic tests on shear-dominated RC columns. 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.
