Abstract

Dhaka, capital city of Bangladesh is one of the most crowded and merely planned megacities in the world, who faces water logging, fire hazard and flood in high frequent rate that sometimes we almost forget about seismic risk. Meanwhile, Dhaka has scrutinized as highly risky city in the world because of its geographic location close to seismically active zones on earth, unplanned urbanization, non-tecnichal construction practice, deficient knowledge on the seismic design of structural system, ignorance of building codes, horrendous construction monitoring by the relevant authorities and lack of coordination between different urban developing authorities. It is predicted by the scientists that a massive devastation in terms of casualities and property damage may be occured if a strong earthquake hits Dhaka. So, it is highly demanded to evaluate the vulnerability of existing buildings to understand the nature of emergency response and earthquake risk reduction strategies are required for Dhaka city in terms of urban planning and design. The aim of this paper is to appraise the earthquake risk of existing structures in different residential areas in Dhaka city. It is expected that citizens from the whole city are may not remain at the same risk. That is why Dhaka has divided into two part - Old and New Dhaka for study purpose. The areas covered under the survey are Mirpur and Lalbagh. Rapid Visual Screening (RVS) and Turkish Methods have been employed for the assessment of seismic risk in residential buildings based on recording various variables from the side way. Depending on the parameters, different performance scores has been assigned to individual building by which the buildings have been classified as safe, moderate and vulnerable. The survey results highlight that seismic vulnerability assessment recognized as 40.9% buildings are vulnerable, 19.3% moderately vulnerable and 39.8% safe. The end result of the study will be advantageous to strengthen the awarness of city authorities, engineers, planers, architects and local dwellers.
