Abstract:
Earthquakes are the natural disaster occurring since
years but during the last two decades they are causing huge looses
whether it may economic or to life. This paper focuses to evaluate
the seismic performance of various building confirming to Indian
standard criteria for earthquake resistant design of structures and
ductile detailing of reinforced concrete structures subjected to
seismic Forces-code of practice, Bureau of Indian Standards, both
as per the revised codes in the year 2016. Due to ground shaking,
seismic loads are the governing load and thus it becomes
necessary to assess the conditional probability of structural
response. Use of HAZUS methodology is followed to construct
seismic fragility curves as it is well-organized and defined
approach. Spectral displacement plays the functional parameter to
derive the expected damage for fragility. This work represented
here is compiled by means of procedure for establishing the
fragility curves for three typical Reinforced Concrete (RC) frame
structures having variations resembling 3 storey intended for
short-period structures, 6 storey used for medium-period
structures and 12 storey representing long-period structures using
SAP2000 as a software tool for analyzing the structure.
Furthermore an attempt is made for focus on the variation of one
of the major structural configuration i.e. slab thickness which is
not certainly paid attention as compared to columns and beams.
Slabs adds additional stiffness to the structure which can
enlighten how it behaviour would be when subjected to ground
excitation. As a result, the fragility curves are plotted to study the
impact due to slab thickness in order they are carefully selected
while design.
