Abstract
Seismic performance of existing RC buildings is evaluated by computing seismic capacity index, Is, using the Standard for Seismic Evaluation of Existing RC buildings, while damage level of RC buildings that undergo earthquakes is assessed by the Standard for Post-Earthquake Inspection and Guidelines for Repair and Strengthening. This research is intended to study Is vs. damage level relations for low-rise RC buildings designed by the old code by conducting dynamic analysis on model buildings with a variety of Is values. The effects of deformability type of columns and number of stories on the relations are studied. Two levels of ground motions, the original level of past earthquake records and design standard level, are considered. In the analysis, column hysteresis is derived from test results. Strength deterioration after shear failure and axial collapse that are commonly associated with hysteretic behavior of old columns, are considered. The method presented in this study enables us to assess the damage level of buildings and the damage conditions of the columns if the deformability type of columns, number of stories, Is value and ground motion are given. In addition, the assessed damage level of buildings is compared with the observed damage level from past earthquakes and the Is value required to prevent collapse of buildings is discussed.
