The ability to simulate the nonlinear dynamic response of RC buildings up to significant levels of component damage is of fundamental importance to evaluate their expected performance for different levels of seismic hazard. In the United States there is an increasing reliance on the provisions in the ASCE-41 Standard for developing models to simulate the nonlinear response of structures during strong earthquakes. Recent changes in ASCE-7 provide the foundation for the use of the modeling provisions in ASCE-41 to perform performance-based design of new construction. Modeling parameters for reinforced concrete columns in the ASCE-41 Evaluation Standard have undergone significant changes since their inception in early 2000s. The original set of modeling parameters, adopted from FEMA 356, was updated in 2007 to incorporate findings from component tests on the drift ratio at axial failure of reinforced concrete columns. Consistent with the philosophy of FEMA 356, the set of modeling parameters introduced in 2007 was calibrated to have a low probability of exceedance. A new set of modeling parameters was recently proposed intended to reflect expected behavior (mean values). While these are positive improvements that are likely to yield more accurate models, the calibration of the modeling parameters in ASCE-41 was based on data sets from component tests, and the effect of the change in modeling parameters on the response of building systems is unknown. Furthermore, while modeling parameters for columns have undergone two updates, modeling parameters for beams and slab-column connections remain unchanged.
