Abstract

The response of an instrumented reinforced concrete moment-resisting frame (RCMRF) building, located in Southern California, was investigated to show how instrumented response can significantly improve the accuracy of performance based design. RCMRF buildings are particularly difficult to model and therefore this uncertainty reduction is very important. A model of the building using FEMA 273 recommended structural design variables is used as a baseline model. Performance based design estimates are made using this model and then compared with estimates made using improved models that benefit from the measured 1987 Whittier and the 1994 Northridge earthquake response of the building.
