The rapid growth of Indian cities in the recent past years has accelerated pressure on the existing buildings and there is a need to develop suitable screening methods for seismic safety of existing buildings relevant to Indian building typologies. Various countries developed different methods for seismic evaluation of existing buildings. These methods consist three level assessments namely rapid visual screening (RVS), preliminary assessment and detailed assessment. This paper presents a study about seismic vulnerability assessment of existing building using rapid visual screening procedure which is the initial stage in the evaluation of existing building takes around 15 to 30 min walk down survey by which structural scores are noted for the existing building according to the building configuration. The structural score less than 0.7 according to RVS data sheet indicates high vulnerability requiring detail evaluation of the building. In this an existing building is initially assessed with RVS and the preliminary assessment i.e. configuration related checks are carried based on as-built dimensions of the building.
