SEISMIC VULNERABILITY ASSESSMENT OF BUILDINGS IN HYDERABAD CITY

India has a range of the world’s greatest earthquakes in the last century. Assuredly, quite one - half space within the country is considered at risk of damaging earthquakes. The northeastern region of the country as well as the entire Himalayan belt is liable to great earthquakes of magnitude over 8.0. the objective of this study is to determine the seismic vulnerability of R.C.C. structures of the Hyderabad City by R.V.S (Rapid Visual Screening) technique and also the Turkish method. Investigations of past and recent earthquake damage have depicted that the building structures are at risk of severe damage and/or collapse during moderate to sturdy ground motion. an earthquake with a moderate magnitude is capable of inflicting severe damage of designed buildings, bridges, industrial and port facilities additionally as giving rise to huge economic losses. The areas covered under the survey are Adarsh Nagar residentia l area, jubilee Hills and Tolichowki. The survey was primarily focused on earthquake problems like identifying building type, plot size and shape, clear distances from close structures, road width and basic data of the building: type of foundation, slab ty pe, year of construction, no. of storeys, no. of inhabitants etc. The detail analysis (or the level - 2 analysis) coated the determination of support space (length x width), column size and direction, lift core size, cantilever length of the building etc. Di gital images of every building from a minimum of two directions were taken. The developers’ names concerned with every building are recorded throughout the survey. The survey process was conducted between 17 - 01 - 14 to 12 - 10 - 15. A database was compiled in M S Access. It was found that almost all of the buildings are RCC structures. The Ground floors of soft storeyed buildings are mostly being used as parking lot. it had been additionally found that almost all of the buildings of the target areas were construc ted without the development of correct disaster resistant system against any potential earthquakes. The use of rapid Visual Screening (RVS) on the study area enables to divide screened buildings into two categories such as those that are expected to posses s acceptable seismic performance and those that may be seismically risky and should be further studied. For additional analysis of the buildings the assistance of methodology proposed by the Turkish method and STAAD software would be taken
