Detailed finite element models of low-rise reinforced concrete walls are appropriate for research and modeling at the component level but inappropriate for seismic design or performance-based assessment for which macro-level hysteretic models of building components are generally needed. The pinching hysteretic model proposed by Ibarra et al. [1] (1KP model) is used to simulate the hysteretic behavior of low-rise reinforced concrete walls. This model includes energy-controlled strength and stiffness degradation under cyclic loading and can simulate successfully the response of steel and reinforced concrete components under cyclic loading. This study presents values of model parameters (i.e., control points associated with the backbone curve and hysteretic energy capacities for deterioration modes) obtained for low-rise reinforced concrete walls by calibration of a small set of test data. Experimental load-displacement data in a digital format are required for this purpose.
