| Description |
The upgradation of seismic design codes and advancement of engineering knowledge
revealed that existing buildings designed as per old versions are seismically deficient. In
order to estimate the additional demand in base shear due to the seismic upgradation of
seismic codes, this paper reviews the provisions of the three revisions of seismic codes viz.
IS: 1893-1966, 1984 and 2002 using seismic coefficient method. The design seismic base
shear depends on the type of building frame, location of the building in seismic zone, site
soil condition, importance factor and response reduction factors given in respective
revisions of IS:1893. Three building models were studied in order to bring out the
increased demand in base shears due to the seismic upgradation of IS: 1893. It is found
from the analysis, the base shear demand of the existing buildings designed as per old
versions of seismic codes (IS:1893-1966, IS:1893-1984) need to be increased to comply
with present version of the code, IS:1893-2002.
