The three models were developed using the open source software platform OpenSees, using the same configuration and different modeling parameters for moment frame columns and beams. Modeling parameters for columns were calculated using the provisions in ASCE 41-13 or new column provisions proposed by ACI Committee 369. Modeling parameters for moment frame beams were calculated using the provisions in ASCE 41-13 or new provisions derived by the authors based on experimental results. Modeling parameters for slab-column connections were calculated using the provisions in ASCE 41-13 for all building models. Models were calibrated using motions recorded at the building site, and used to perform incremental dynamic analyses to evaluate the effect of modeling parameters on the calculated collapse intensity and collapse mechanism of the building. All models developed lateral instabilities due to two-story mechanisms involving the fourth and fifth floors signaled by a very abrupt change in the slope of the relationship between the Intensity Measure and the Maximum Story Drift ratio. This type of behavior was associated with a large number of columns in the fifth floor experiencing shear failure and developing negative slopes in their force-deformation curves. The intensity measure at collapse was affected significantly by changes in the modeling parameters defining the capping rotation and the drift ratio corresponding to total loss of lateral stiffness of the columns, and was not sensitive to changes in the modeling parameters of the beams.
