From the historical records, geological evident and recent trends in earthquake, it is evident that Bangladesh is in a high-risk zone of earthquake hazard. The recent results of the CDMP, if a huge earthquake greater or equal to seven magnitude happened in this country, would lead to a serious human tragedy due to the defective structure. In Lalmatia, Dhaka study area there are various types of structures as like as RCC, masonry, semi-pucca etc. and the area has different old and newly filled soil development. This study considered the characteristics of RCC building elements and their behaviors to assess the risk against earthquake vulnerability in Lalmatia using the Turkish method. Next building vulnerability from Turkish Method used as one total vulnerability factor. In the method of this research, a pair wise comparison matrix for a numerical relationship between two elements and the Analytical Hierarchical Process (AHP) model has been applied to decide in weight and to get rank of the vulnerability factors. By weighted sum vector among the six factors and calculating vulnerability index (VI), the overall vulnerability were identified in Lalmatia. Using Geographic Information System (GIS) and defining an ordinal scale of calculated result, the vulnerability status of single buildings of the study area is presented here. This research tells that 8.23% buildings are highly vulnerable and 14.24% buildings are moderately vulnerable to earthquake. About 77.53% buildings are less vulnerable. As the study area is in a major urban center (Dhaka City), the scenario of unplanned urbanization increases the overall vulnerability to higher scale.
