Abstract:
Many existing reinforced concrete structure in
present world are inadequate for earthquakes. Recent
earthquakes which occurred during last decades have
indicates that major damage occurred was not directly due
to the poor performance of structure during earthquakes.it
is recognized that the most effective method of reducing
risk of damaging structure is sesmic retrofitting. In recent
year significant improvement of retrofitting techniques.
Thus study highlights the principals of assessing and
retrofitting of structure against seismic events.. Finite
Element Method used to investigate the performance of the
building during the earthquake and to check the behavior
of the structure after applying retrofitting techniques. The
methods such as steel and concrete jacketing and
application of fiber reinforced polymer (FRP) composites,
which are used to improve the load bearing capacity of
individual structural elements, are highlighted and
methods such as shear walls & shear cores, which can be
used to improve overall stability, are enlisted and the
factors that governs the decision for retrofitting of the
structures are discussed.
