The Buildings, which appeared to be
strong enough, may crumble like houses of cards
during earthquake and deficiencies may be
exposed. Experience gain from the recent
earthquake of Bhuj, 2001 demonstrates that the
most of buildings collapsed were found deficient to
meet out the requirements of the present day
codes. In last decade, four devastating
earthquakes of world have been occurred in India,
and low to mild intensities earthquakes are
shaking our land frequently. It has raised the
questions about the adequacy of framed
structures to resist strong motions, since many
buildings suffered great damage or collapsed.
Under such circumstances, seismic qualification of
existing buildings has become extremely
important. Seismic qualification eventually leads
to retrofitting of the deficient structures
In the proposed investigation a
performance based evaluation and retrofit of an
existing hostel building in Babasaheb Naik College
of Engineering, Pusad. Built in 1987, the subject
hostel building is a four-story, rectangular
structure. A nonlinear static pushover analysis
using the displacement coefficient method, as
described in FEMA 356, is used to evaluate the
seismic performance of the existing building. A
seismic retrofit using energy dissipating device
based on pushover analysis is proposed for the
life-safety target performance of the existing
building.
