Introduction:
• Earthquake is destructive natural disasters
• Nepal is earthquake prone area
• Traditional building stock in Bhaktapur city is of
Masonry structures (with mud and Timber floor)
• Seismic vulnerability (measures of seismic strength or
capacity of buildings)
Why seismic vulnerability assessment?
• Seismic vulnerability is needed for
– to understand the current condition of the structures
– To reduce the damage of buildings during earthquake
– To determine method of strengthening
– for the allocation of rescue forces and equipment to
vulnerable area
– Assessment is not done yet in selected area
Vulnerability assessment methods:
• Seismic vulnerability assessment methods as per their
requirement in content to their country
– Rapid Visual Screening of Seismically Hazardous Building
(FEMA 154)
– HAZUS (HAZARD US)
– Risk Assessment Tools for Diagnosis of Urban Area against
Seismic Disasters (RADIUS)
– Seismic Vulnerability Assessment according to EMS-98
Continue………
• In context of Nepal the above methods have some
deficiencies
– Difference in material and technique of building construction
– Traditional building topology
– There is not its own assessment method in Nepal
– Relation between these above methods are not workout
Literature Review:
• G.M. Calvi, R. Pinho, G. Magenes, J.J. Bommer, L.F. Restrepo-Vélez and
H. Crowley "DEVELOPMENT OF SEISMIC VULNERABILITY ASSESSMENT METHODOLOGIES OVER THE PAST 30 YEARS"
The seismic vulnerability of a structure can be described as its susceptibility to damage by ground shaking given level of damage to a given building type due to a scenario earthquake. The various methods for vulnerability assessment that have been proposed in the past for use in loss estimation can be divided into two main categories: empirical or analytical, both of which can be used in hybrid.

ASSESSMENT OF VULNERABILITY OF CRITICAL INFRASTRUCTURES DUE TO EARTHQUAKE IN SYLHET CITY AND MANAGEMENT
In this paper, results are presented on the assessment of seismic vulnerability of buildings in Zone III of Sylhet city, Bangladesh. This study was based on a methodology for earthquake vulnerability analysis using Rapid Visual Screening (RVS) and a structural scoring system (S value >2 indicating Seismic safety). The survey showed that most of the buildings studied in the city fell in the category of seismically moderate to high risk range (S value of 2 or less). Criteria for construction of seismically safe buildings have been proposed.
Objective:
• Prepare inventory of buildings stock of a specific
area of Bhaktapur city.
• Determine the topology of buildings.
• Determination of materials conditions (damage state).
• To assess seismic performance of building.
Continue………
• To determine the seismic vulnerability index of
buildings in research area.
• To find out the appropriate methods of vulnerability
assessment in context of Nepal.
• Preparation of base map in GIS with Vulnerability
of buildings
