AbstractAn approach is studied to evaluate the damage states drifts of reinforced concrete columns based on crack widths. Shear cracks and flexural cracks are the main crack types, considered for the lateral drifts estimation of reinforced concrete columns. Load-Lateral drifts relationships at the damage states were estimated based on shear crack angles and truss mechanism. A constitutive law was modified for compression diagonal strut concrete of the analogues truss. The analytical outputs were compared with the experimental results of sixteen-tested reinforced concrete columns subjected to static cyclic unidirectional reverse lateral load and applied axial load with different shear capacities.
