The response of an instrumented reinforced concrete moment-resisting frame (RCMRF) building,
located in Southern California, was investigated in this research and compared to the response
of linear elastic analytical models of the building. RCMRF buildings are particularly difficult
to model when the objective is to predict the performance of the building. Therefore, nine
models of the case study building were created by making three assumptions for the stiffness of
the beams and columns and three assumptions for the stiffness of the beam-column joints.
Fundamental periods for the models were compared to the fundamental periods calculated directly
from the building response recorded during the 1987 Whittier and 1994 Northridge earthquakes.
In addition, the analytical models were subjected to the ground accelerations recorded during
the Whittier and Northridge earthquakes in a time history analysis and the maximum floor
displacements compared to the recorded floor displacements.
