This building was typical of many medium rise reinforced concrete bearing wall buildings designed and built in Chile during the period 1996-2009. Understanding the response behavior and collapse mechanism of the Alto Rio building during the Maule earthquake is very important for the earthquake engineering community. For this purpose, a detailed three-dimensional nonlinear model of the complete Alto Rio building was developed in the OpenSees analysis framework using the beam-truss modeling approach. The geometry of the structure was obtained directly from the AutoCAD design documents of Alto Rio. Realistic cyclic material constitutive models were used for the reinforcing steel and concrete materials. This paper discusses some details of the building model and key results obtained from a nonlinear pushover analyses and a nonlinear time history analysis, which shed some light on the cause of collapse of the Alto Rio building.
