Abstract
A pair of ½ scale 3-story, 3-bay concrete bare frames were tested by the pseudo dynamic (PsD) testing procedure. Both frames represent common deficiencies of non-seismic construction. Continuous column reinforcement in one specimen and insufficient lap splices at the bottom ends of columns in the other specimen was the only difference. Measured seismic performance of both frames was assessed by using the rotation and strain based acceptance criteria of two different seismic codes. Dynamic responses of both frames were also predicted by employing nonlinear frame models. Analytical models of deficient frames were capable of predicting global deformation response, but failed to predict local deformations. Prediction of local deformations in deficient frames can only be improved if joint deformations and hysteretic degradation in member properties are considered directly in the analytical models.
