Bridges are important structures which play a key role in transportation of goods and people from one place to another. Its accessibility is hindered during natural hazards such as earthquakes. This phenomenon necessitates the seismic assessment of reinforced concrete bridges. While conducting the seismic vulnerability assessment of such structure, keen attention is required to the characteristics and intensity of ground motions. In light of the above statement, the present study focuses on quantification of seismic damage of bridge, designed as per Indian standard codes under near field ground motions. Some of the inherent characteristics of near field ground motions such as PGV, pulse indicator, pulse period, impulsivity index, etc. are influencing factors in vulnerability assessment are also considered in the study. A nonlinear concentrated hinge based finite element model is used for seismic vulnerability assessment. Responses obtained from the analyses show that severe damage occurs in the structure when it is subjected to near fault ground motions specifically when it is inbred with certain characteristics. The study also reveals that before conducting the seismic vulnerability assessment of structures, it is significant that all characteristics of ground motions should be closely characterized.
