This paper presents research carried out on damaged reinforced concrete structure using forced vibration
technique. Half scaled model of reinforced concrete special moment resisting frame (SMRF) was investigated, which was
designed as per Building Code of Pakistan for seismic zone 4. This structure has been tested already dynamically that
caused minor damage in the structure columns. The present study now focusses on measuring the dynamic
characteristics of damaged reinforced concrete structure in order to understand how the pre-existing cracks and damage
in the structure affects the elastic dynamic properties (frequency and elastic damping).
